Re: Application Crashes at mfc42!CMapStringToString::GetAssocAt+14

This sounds like a kind of race condition to me. Are you accessing this map from two separate threads ? If yes, make sure that you protect the map against concurrent access (with a critical section for instance). The problem might appear because two threads access the map at the same time, so the map is in an invalid state for one of the thread.

Hi Cédric Moonen,

Thank you for the response.

This Map is completely used by one thread but still I want to implement your suggestion and test it.

If you notice the MFC42.dll calls, there is something strange. I'm not understanding why CMapStringToString class's GetAssocAt() is called. It is supposed to call CMapStringToPtr class method.

thanks,
Mallik

How to change the clsid of an ocx?

HI All,

I have one ocx control developed in vc++/mfc and later the same code has been modified to use in automation server..now the problem is we need to keep separate clsid for the ocx control for server to avoid any conflict but its not changing the clsid even after changed in odl file..

Please show the right way to do this.

Thanks..

How do you know that (I'm assuming you've succesfully built the component with the new CLSID)?

Cannot you find the new CLSID in the registry?
Have you changed the interface name? Cannot you use the Oleview tool?

insert records using parameters .

How do i insert a recordset where i take parameters from the user.

User enters his values in editboxes and when he hits "insert" button a query is fired

insert into table1 values (editboxvalue1, editboxvalue2 , editboxvalue3 , editboxvalue4 );

For this i can take values from editbox with the GetWindowText() method and store it in some variable .

but how should the query look like ,and should i use Connection::Execute() or Command::Execute() for this.

I have been using Connection::Execute( ) to Insert ,Update and Delete a recordset.

For queries with parameters which is a better choice ???

And how to form a insert query to insert values from user,into DB ???

Command::Execute, after appending a suitable number of parameters[^].

ToolBar Bitmaps?

Software200719-May-09 4:38

19-May-09 4:38

Hi,

How can I load/insert an existing bitmap to the existing main application Toolbar? I do see where I can draw/Edit a new bitmap, but I have a bitmap that I downloaded from somewhere and I need to load that instead? How is this done usually?

Thanks

One way is to simply copy it over the existing toolbar.bmp file. If it's already sized correctly, you're good to go.

Thanks, I think I did that...I noticed the bitmap I am trying to copy has a different bit depth, like way off than the rest of the bitmaps for the toolbar...Would this be a reason to make it fail?

Fail as in none of the buttons work, or just looks funny?

No, as in my copy method is not doing the trick. I opened the toolbar in Resource Editor and tried to copy over the bitmap, but no success. Am I doing wrong?

It isn't working...In Explorer, I browse to where the bmp(s) are, I have Toolbar.bmp and MyBitMap.bmp, I tried opening toolbar.bmp and copying Mybitmap over it, also, just tried drag and drop without opening...I must be missing something, becasue i wouldn't think it would copy the bmp file over another file (the Toolbar.bmp has the image of the tollbar bitmaps, but not editable obviously)...What do you think am doing wrong?

Thanks

Can't you just delete toolbar.bmp and rename MyBitMap.bmp to toolbar.bmp?

The bitmap must be redrawn or converted to 3.x format. You might check to see if Paint (mspaint.exe) will do this for you.
