.NET Forum / Visual Studio.NET / Setup / November 2004Help
Hello, I get this error when I try to bring an application written in VB 4 into VS 6?? Could not find Data Access Library. Cannot Create reference. Visual Basic tried to create a reference to the Microsoft DAO Object Library through the Data control, but failed. Verify that all system registry keys are valid and, if they are not, run Visual Basic setup again. ---------------------------------------------------------------------------- ---- Send feedback to MSDN.Look here for MSDN Online resources. Thanks Russ Hi Russ, Thank you for your post. Based on my experience, the error message is very likely to occur if the file "DAO350.dll" and "DAO360.dll" are not registered properly. Please use the command "regsvr32" to register the file to see whether this helps. Should you have any concerns, please feel free to post here.

Hello Wendy, My system could not find the files to register them. I think I need VB6 SP 3? Could not find it on Microsofts site? Thanks Russ > Hi Russ, > [quoted text clipped - 12 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "as is" with no warranties and confers no rights. Hi Russ, Thank you for your response. As far as I know, by default, the file "DAO350.dll" or "dao360.dll" should be in the folder "C:\Program Files\Common Files\Microsoft Shared\DAO". You may navigate to this path to check whether they exist. From your description, I understand that you would like to install Visual Studio 6 Service Pack 3. I suggest that you install the latest Service Pack 6 for Visual Studio 6.0. You may download it from the following link. Service Pack 6 http://msdn.microsoft.com/vstudio/downloads/updates/sp/vs6/sp6/default.aspx Should you have any questions, please feel free to let me know.

Wendy, The files are there but will not register??? Below is the Path Statment: PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\PROGRA~1\COM MON~ 1\SONICS~1\;C:\Program Files\Microsoft Visual Studio\Common\Tools\WinNT;C:\Progr am Files\Microsoft Visual Studio\Common\MSDev98\Bin;C:\Program Files\Microsoft V isual Studio\Common\Tools;C:\Program Files\Microsoft Visual Studio\VC98\bin Thanks Russ > Hi Russ, > [quoted text clipped - 9 lines] > > Service Pack 6 http://msdn.microsoft.com/vstudio/downloads/updates/sp/vs6/sp6/default.aspx > Should you have any questions, please feel free to let me know. > [quoted text clipped - 4 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "as is" with no warranties and confers no rights. Hi Russ, Thank you for your update. However, I do not quite understand your meaning. I doubt whether you mean you can find "DAO350.dll" and "dao360.dll" under the path: C:\WINDOWS\system32; C:\WINDOWS; C:\WINDOWS\System32\Wbem; C:\PROGRA~1\COMMON~1\SONICS~1\; C:\Program Files\Microsoft Visual Studio\Common\Tools\WinNT; C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin; C:\Program Files\Microsoft Visual Studio\Common\Tools; C:\Program Files\Microsoft Visual Studio\VC98\bin I also installed Service Pack 6 for Visual Studio 6 on my test machine. I am not able to find so many files. Currently, I would like to provide some steps to register the file. I hope it will be helpful. 1. Click "Start" => Click "Run" => Type "cmd" in the open blank. 2. In the command Prompt, please type the command: (For example) regsvr32 "C:\Program Files\Microsoft Visual Studio\Common\Tools" Note 1: Please do type the command instead of copying and pasting it, since the quotation marks are mangled by the email formatting. They are now invalid for commands. Note 2: Please don't omit the quotation marks in this command. Note 3: Please don't forget the blank after the number 2 3. You should see the dialog box showing "DllRegisterServer in C:\Program Files\Microsoft Visual Studio\Common\Tools" I hope this is helpful. Thank you!

Wendy, I got the two dao files registered but it still is not happy wants DAO 2.5 Object Library???? See Below: Visual Basic Reference The project file 'item1' contains invalid 'item2' key value. Valid range is 0 to 'item3' The key value specified in the .VBP file was out of range. This error has the following cause and solution: a.. The .VBP file contains a key value that is not in the specified range. The file may be corrupt. Install a backup copy of the specified file or modify the file using a text editor to correct the error. Warning Modifying a Visual Basic file in an editor other than Visual Basic may corrupt the file. This is only recommended for advanced users. -------------------------------------------------------------------------------- Send feedback to MSDN. Look here for MSDN Online resources.

Hi Russell, I think you may try to create a new vb6 project and then copy and paste the code from vb4 project to vb6 project to see if that works for you. If this still did not work for you I think there may be something wrong with your machine environment. You may try to add reference to the Microsoft DAO 2.5/3.5 Compatibiliry Library, which is an tlb file. You may try to use the regtlib.exe to register the Dao2535.tlb which is located in the path below. C:\Program Files\Common Files\Microsoft Shared\DAO\Dao2535.tlb http://groups.google.com/groups?hl=zh-CN&lr=&c2coff=1&selm=004401c31db3%2411 094ec0%24a001280a%40phx.gbl Hope this helps. Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Peter I think it is that I only have the exe file and not the original vbp file that has been my problem. It is a 217k file that was left by a DOD worker that I was hoping to save for the Navy. I wish there was a way to get this done.

Hi, Do you mean you have a project.exe file which is built in vb4.0 and now you want to run it under vb6.0? To further troubleshooting the problem, I think you may try to usethe regmon and filemon tool to monitor the file and registrykey access status when we run the project.exe to see if there is any notfound or access denied information. You may get the two tools under the link below. http://www.sysinternals.com/ntw2k/source/filemon.shtml http://www.sysinternals.com/ntw2k/source/regmon.shtml Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Peter, I would like to convert the VB4.0 to VB6.0 It is about a 217k exe file thar access a mdb database... Thanks Russ > Hi, > [quoted text clipped - 19 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Hi Russell, I have some confusion with your scenario. Now I have to confirm you with some information. 1. Do you have the VB4.0 Project file or you just have the compiled EXE file? 2. If you just have the exe file, I think we can not open it with VB6.0 ide and then recompiled it into exe file. 3. Now your problem is that when you run the compiled exe file, you get the error that some dll can not be found, am I right? 4. If so, I think you may to use the regmon and filemon tool to see if there is any registry or file permission missing as I suggest you in the last reply? If I have any misunderstanding, please feel free to post here. Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Peter, You are right! I just have the exe file and it opens a dao data base in Access 2.0 as the place to store the records. I was hoping to save the source after a decompile and recompile as a VB 6 Application. It ran in Win 98 Access 97 machines but time has moved on and it needs work. Do I also need to convert it to Access ADO file type? Thanks Russ > Hi Russell, > [quoted text clipped - 26 lines] > This posting is provided "AS IS" with no warranties, and confers no > rights. Hi Russell, Once we have compiled a VB application into binary mode(EXE file), we can not convert it back into VB source file(.frm, .vbp and so on) We can only convert it into assembly language which is more related with low level and computer related. That is different from the advaced language such as VB. That is why every software will care its source code, because with source code every one can change and compile a new build for sale. Because it is almost impossible to redeisgn a software based on it binary format(exe format). I think you may have to contact the original software development engineer or company to see if they have any available source code for the software.

Peter, I have tried to contact the original programer no luck. I need to register DAO 2.5 in VB 6 how is that done? Thanks Russ > Hi Russell, > [quoted text clipped - 18 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Peter, It says: and I answer Yes The project file QATS.vbw contains invalid key 'Module1', continue loading project? Yes The project file QATS.vbw contains invalid key 'frmAbout', continue loading project? Yes The project file QATS.vbw contains invalid key 'frmMain', continue loading project? Yes The project file QATS.vbw contains invalid key 'frmSecurity', continue loading project? Yes The project file QATS.vbw contains invalid key 'frmSelect', continue loading project? Yes The project file QATS.vbw contains invalid key 'frmMonitor', continue loading project? Yes The project file QATS.vbw contains invalid key 'Monitor', continue loading project? Yes The project file QATS.vbw contains invalid key 'frmFiles', continue loading project? Yes It then tells me this project was developed in a previous version of VB, If the code in this project declares variables of data access objects, such as Database or Dynaset, the project must now reference to the Microsoft DAO 2.5 Object Library. Choose Add to add this library reference now. I then choose Add and it says Could not find Data Access Library. Cannot Create reference????? How do I add this Data Access Library so it can be found? > Hi Russell, > [quoted text clipped - 18 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Hi Russell, As I said in my former post, VB6 support DAO2.5 by using the Dao2535.tlb You may try to add reference to the Microsoft DAO 2.5/3.5 Compatibiliry Library, which is an tlb file. You may try to use the regtlib.exe to register the Dao2535.tlb which is located in the path below. C:\Program Files\Common Files\Microsoft Shared\DAO\Dao2535.tlb Also it is strange that the project.exe file will popup the message as you said. Are you sure that exe file is the compiled VB4 executive file? Can you send me the file for me to have a reproduce test?

Peter, Did you get the zip file ok?? Thanks Russ > Hi Russell, > [quoted text clipped - 8 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Hi Russel, I am sorry for delay responding. The project can not run on my machine, and I get a different error. Run-time error '336': Object server not correctly registered Without source code it is hard to guess what had happened. Which is different from what you provide before. How do you deploy you vb4 project to vb6? As I said before without source code we can not just deploy a vb4 exe to the vb6 ide and compile. In vb, if we need to deploy an application we need a setup project. for simple project, maybe we can do it by just copy the exe file, but for complex one we do need the setup project, because just copy will not work without some additional operation by setup project. So far the only approach is to call your software develop vendor, or you had to run the project on the original machine which will work. Thanks for you understanding!

Peter, Do you know Kevin he was helping me aalso in a different news group? see below: Some Win2000 Pro machines do this to me also, runs on WinXPro. Kevin, DAO 25 and it happens when I try to Load the project.A series of key associations problems happen first then the error. Thanks Russ > Hi Russ, > [quoted text clipped - 9 lines] > "This posting is provided "AS IS" with no warranties, and confers no > rights." > Hi Russel, > [quoted text clipped - 30 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Hi Russell, Yes, I know that Kevin had ever given some suggestion to you. And that is why he redirect you to this thread. As I said before, how do you deploy the project onto another machine? Do you have the deployment setup program? Do you mean some windows 2000 and windows xp machine will OK to run the program? Then what is the different between the two machines(some windows 2000 will work. and some will not)? Are you using the same setup project to deploy the program? Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Peter, I just copy the files to a folder named Qats. At work it runs from a Win 2000 server. Right now I have two machine's at home running Win XP it runs on one but not the other? One has VB 4 and the broken one runs VS 6??? I suspect the problem lies in the drivers for access but not sure at this time? This is why I need to update the source to VS 6 to end the madness..... If I pull the TFS MDB file into access 2000 I have to run a module to convert the MDB file to access 20 in order for the VB 4 Qats program to use the MDB file.... in the other newsgroup Matt said there was a decompiler for VB4 but the site is down??? Sorry this is so much of a deal. Thanks Russ > Hi Russell, > [quoted text clipped - 17 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Hi Thank you for you input. From vb4-vb5-vb6, some controls has been changed and introduced new feature. Since we have no the source code it is hard to guess what control has caused the problem. Also we have official vb decompiler to do the decompilek, so far I think you have to run the application on windows 2000 or as I said it is important to contact your software development team for the original source code so that we can try to recompile it in vb6, or if your software development do not want to provide source code, you may try to ask them for a version for vb6. Thanks. Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Peter, I have taken on this project for my office. The person who wrote the software is gone?? If there is an official VB decompiler as you state how do I get this call Mr. Gates? Do you have a contact at Microsoft, that I can call on this problem, so that I can get this resolved? You have been a great help but I am a one man team on this now. So I guess I may have to recommend to the Navy to just drop this application? Thanks Russ > Hi > [quoted text clipped - 19 lines] > Get Secure! - www.microsoft.com/security > This posting is provided "AS IS" with no warranties, and confers no rights. Hi Russell, Since the vb4 is a very old product, it may have some incompatibillity with the current newly control/library/OS. And we have no source code, it is hard to convert it into the vb6 version. Also I think you may try to contact MSPSS, but I am afraid that may not give your further suggestion. Anyway you may have a try and you can reach MSPSS via the link below. http://support.microsoft.com So far I think the alternative approach is to run the application on the original machine or you can build a virual machine image to run the application. Hope this helps. Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Hi Russ, I also reviewed the whole issue thread. First of all, I don't think there is any official VB decomplier. Second, since you have no source code and we can't contact the original programmer now, we are lack of enough information to fix this problem on a newer OS and VB 6.0. As Peter suggested, the best way should be build a VPC Win9X image and run your application on that. In this way, you can still work on a newer OS and run this appplication. You can also contact Microsoft PSS (Product Support Service) by contacting us at 1-(800)936-5800 or by choosing one of the options listed at http://support.microsoft.com/default.aspx?scid=sz;en-us;top.
