.NET Forum / Languages / C++ Libraries / May 2004Problem with resources of Dll
I have a SDI program which contain one dll. There are some resources in my program like string table, toolbar,icon etc. I insert one extra resource DialogBox(IDD_DIALOG1) and one menubar(IDR_MENU1). I load and set IDR_MENU1 in CMainFrame::OnCreate() and display IDD_DIALOG1 in any event in my program. I add a dll to project.I copy all these resources in my dll. Then i load this dll and set resource handle of this dll. When i run program on win2k, it run successfully and load the resources of dll when i load this dll. But under win98, it doesn't load the resources(menu and dialog) of dll while toolbar and string resource of dll are loaded in win98.There is no problem for win2k at all. My code for loading the dll is HINSTANCE dllhandle = NULL; dllhandle = LoadLibraryEx("mydll",NULL,LOAD_LIBRARY_AS_DATAFILE); if(dllhandle) AfxSetResourceHandle(dllhandle); for menu HMENU menu; ::SetMenu(m_hWnd,NULL); menu=LoadMenu(langDLL,(LPCSTR)IDR_MENU1); ::SetMenu(m_hWnd,dllhandle); In CMainFrame::OnCreate() first i load menu from exe resource. It loads. But for any dll, it doesn't load menu and dialog. Above problem is only for win98.My project is in statically link library.This is not UNICODE program. Is there other method to load resource of any dll for win98? Please reply. Waiting Hi Manoj I assume the 2nd param to ::SetMenu() was actually meant to be "menu" and that what you typed in your msg was just a typing error What error code do you get back from LoadMenu() When running this in the debugger, do any interesting msgs show up in the debug output window when the menu tries to load You might also find it useful to run the free "FileMon" utility from www.sysinternals.com (with which I am unaffiliated). This will let you monitor _all_ file activity [you can filter it down to just your application to make it manageable] and you should be able to see what file it's trying to read from while doing your ::SetMenu() call It's been a while since I used Windows98, but I vaguely recall there was some minor difference in the order of searching for resources. Don't spend too much time on this possibility, because my memory here is uncertain One other thought: try changing your resource IDs (add 370 to all of them or something like that) to see if there is some odd collision with the resource numbering Hope something here is of some help Larr sORRY, i mistakenly write it.it's ::SetMenu(m_hWnd,menu); LoadMenu does n't give any error. I used GetLastError() and FormatMessage(). for win98, it says "Operation completed successfully". But LoadMenu returns NULL. LoadMenu(langDLL,(LPCSTR)IDR_MENU1); using langDLL i load strings of dll(LoadString) and toolbar. It loads them. But for menu, it returns 0. Dialog box of dll doesn't load.and DoModal returns -1.

Please reply. > Waiting I know that on Windows 98 has problems with Resource IDs that are above 0x7FFF. Example (see return values section): http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/bas e/loadlibrary.asp The link you give http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/bas does not find on MSDN. Please give other link. And me how to solve this problem for win98 Thanks > The link you give http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/bas > does not find on MSDN. > Please give other link. The link is all there but was broken. I'm sure you can figure it out. If you can't just go to msdn.microsoft.com and search for "LoadLibrary". > And me how to solve this problem for win98 Are you the OP? What is your problem or question precisely? The best solution is to not use Windows 98. The .Net framework was never intended run on 98. Microsoft was going to stop supporting 98 earlier this year but didn't because of public out cry. In fact they prevent you from installing Visual Studio .Net products on 98. I repeat, The .Net framework was never intended run on 98. I already told you my problem. I repeat it again. I made a pure unicode Application in VC7(dotnet) on win2k (not on win98, I know it very well as you said) . I gave MSLU support to my application. So it can run on win98,WinMe. Suppose my Application name is MyApp and i use two Dlls with MyApp.My OS default language is English(US).I use one dll for Chinese Language and other for Japanese Language.I use these two Dlls because when i run MyApp, i select resources of these Dlls.So user can see Resources of my application in English,Chinese and Japanese.When i choose Japanese Language,i select all resources of Japanese Language so user see all resources in Japanese not in English. Now my Question is When i run my application on win98,WinMe(I run its .exe with above two Dlls). It runs on Win98 successfully. When i select Japanese Language then i see Japanese Resources(Toolbar,StatusBar and String Resources).But Menu and Dialog box of Japanese Language are not displayed.I test MyApp on Win98(OS Language English) and Win98(OS Language Japanese).In both cases, menu and dialog boxes are not displayed.Remember if Win98 OS language is English, then i see japanese strings as ?????. If Win98 OS language is Japanese then i see actual japanese strings. Note that menu and dialog of any dll are not displayed under Win98. If i add one extra Dll(for English Language) to MyApp. Then under Win98, its menu and dialog are alse not displayed. I use LoadMenu() and SetMenu(). Please note Menu and dialog of MyApp are displayed. But of Dlls are not displayed. As you said, use LoadLibrary(), I say,it doesn't work for Unicode(under Win98) because i have tried it. I used LoadLibraryEx(). I hope you understood my problem now. and please don't use bad language. What's OP?

This sounds like a new problem or else you isolated your problem further. > I hope you understood my problem now. What I understand is that you're trying to get predictive Unicode support out of Windows 98. Good luck on that one. The previous issue I responded to was errors resulting from using LoadMenu. I sent you a link that states that Windows 98 has problems loading resources who's numeric identifier is > 0x7FFF. Example: Windows Me/98/95: If you are using LoadLibrary to load a module that contains a resource whose numeric identifier is greater than 0x7FFF, LoadLibrary fails. If you are attempting to load a 16-bit DLL directly from 32-bit code, LoadLibrary fails. If you are attempting to load a DLL whose subsystem version is greater than 4.0, LoadLibrary fails. If your DllMain function tries to call the Unicode version of a function, LoadLibrary fails. > and please don't use bad language. What bad language are you talking about? > What's OP? "Original Poster". I asked if you were the original poster because you changed your display name in the article tree. You should avoid this in the future as it is confusing. ... Thanks You are absolutely right for LoadLibrary(). It fails between win32 and win16. But i use LoadLibraryEx(), it doesn't fail. For unicode we use LoadLibraryExW(). It loads the any dll. In dll, i use its resources like DialogBox, Toolbar,MenuBar,Statusbar and string table resources. When i load any dll then its toolbar,statusbar and string table resources are loaded in my exe successfully. But its menu and dialog box are not loaded. So my problem is with menu and dialog box. I want to know why they are not loaded? Now talk about numeric identifier is > 0x7FFF. I made an UTF-8 program. It successfully run on all windows. and it's resources numeric values are same as my this UNICODE program(i.e. >0x7FFF). But in UTF-8, i used AfxLoadLibrary() because project was in shared dll. MSLU says use static linking, so in UNICODE program,i can't use AfxLoadLibrary() because this function is for dynamic linking. I hope a reply from your side.
