Error: failed to load message box prompt string (AfxMessageBox, Loadstring)

I use VC++ 4.0 and I have two .RC file for the same resource.h file. Actually, one is for the french resources and the other for the english ones.

Yes, I admit it, maybe I modified in a text editor either the .RC or resource.h files! But as a result, I get an assertion failure in line 177 of appui.cpp telling me the specified string resource has not been found. The call is made by AfxMessageBox to pop up a dialog box displaying the message identified by a string resource. In fact, all resources not called by AfxMessageBox work fine.

My app used to worked just fine before I started playing with my resource files, so I'm convinced it's not the code which is wrong.

I believe that if I redefine all resources from scratch will do the job, but since there are quite a bunch of them, what can I do to restore my resources files in an uncorrupted state?

Thanks!

Why don't you tell us what id string resource was not found?

If it is a standard resource, you can may be able to get it from prompts.rc and/or afxres.rc

But cannot help much without the ID number.

The message identified by the MACRO in your LoadString() function call is probably not in the resource file you are using.
You should get the number from the resource.h file and verify that it in the .rc file that you are compiling and linking to your program.

It's a string resource I created myself and when I open my rc file and resource.h files, I can see the resource number and identifier. While debugging, I tried to replace the string identifier with another one I had created before: the same error message appears. And guess what, this resource string is found when displayed as a description of a button in the toolbar. So it seems like it's not a particular string resource which is not found but rather any string resource called by AfxMessageBox and LoadString. By the way I use the T_ macro:

AfxMessageBox (T_(mystring.LoadString(IDS_MY_STRING),...

As I said before, this line of code used to work and only my resource files have been updated.
