I see your query is answered.

In addition, DO NOT use SMS language anywhere on this site. Next, this is the C++ forum and you should only ask C/C++/MFC queries here.

hii,
I am getting "Error Creating bitmap!" in EVC++ 4.0 on Window CE 5.0. I don't where this error came from. I am using
CreateCompatibleBitmap and BitBlt for drawing the screen. I have checked all Error codes , but no luck.

Description of Error :
It’s the SNAP window with the “error creating bitmap” message.

“Snap” is in the blue portion

“Error Creating Bitmap” in gray portion

Thanks and regards,

May be you can check if the device/emulator has enough memory to hold newly created bitmap.

You can also use the GetLastError() API to know the exact reason for failure.

Try making HBRUSH bgcolor; a global variable.
Also set the brush in DC which is received in WPARAM of WM_CTLCOLORDLG message.

Use GetCursorInfo to get the cursor information [^] and using the CURSORINFO struct you can get the cursor state, tells you whether cursor is hidden or shown [^]. Smile | :)

But if you are looking for the window to get active then try with GetWindowInfo [^], which will give whether the specified window is active or not.

In MFC using a MS Access Database will NOT allow more Tahn 255 Chars even with setting RFX_Text to 1024 length

I cannot get the MS Access Database to accept over 1000 chars into a column using the RFX_Text that is set to 1024 length (See Previous Post CMyDB.cpp RXF listing).

Does anyone know how to do this in MFC?

This may be a restriction posed by Access, i.e., the maximum length of a text field in Access is 255. If you want to store longer strings to a database field, you may need to look for something else, such as SQL Server. For smaller applications, you may use SQLite.

Unless the maximum was increased in Access 2007, the limit for Text fields is 255. With a memo field, you can store up to 65535 characters.

Yess, David,   it is still 255. My field is set to Memo rather than text. but still it is NOT accepted by the Access DB; though eactly 918 chars was there before the Update() was called.

long nMaxLength = 1024;
     RFX_Text(pFX, _T("[Instructions]"), m_Instructions,nMaxLength);// 918 chars loaded

Less than 255 loaded into DB!!!

I have no idea why this is happening.

David A question nfor you personally: Was you ever able to setup the Edit() and Delete() functions in your program you sent me?   Let me know if/when you have this.

Thanks.

Copying files from an archive

Code-o-mat14-Dec-09 12:02

Hello folks!

A theoretical question in 2 parts:
1. is it possible to copy files to which i have only an ID list (so no "text representation" of the path like "c:\folder\file" and i can't get one either)? I mean something like SHFileOperation[^] but with IDL's, not paths.
2. If it is possible, would this work on files inside an archive. I mean, -let's say- i have the ID list to a file that is compressed inside a ZIP archive (you can get this by asking for an enumerator from the shell interface object that represents the ZIP archive and then enumerating the files, however, trying to convert this ID list into a path seems to fail). Could i copy this file using the method mentioned in question 1 to some other location and "trust" the shell to perform the required uncompression and such "invisibly"?

Or a different aproach: is it possible to get a valid path to a file compressed into an archive that the shell can process, i mean something like "c:\folder\compressed_archive.zip\file_inside_archive.ext"? As i said in part 2, one seems to be able to get the ID list to "file_inside_archive.ext", but SHGetPathFromIDList[^] won't take it.

Thanks in advance for any suggestions or ideas.

Thanks for the reply!

Sadly, as i said in my post, SHGetPathFromIDList fails on IDLs of zipped files. The documentation says SHGetPathFromIDList works only on file-system objects, i guess a file compressed into an archive is no longer considered part of the filesystem, it's rather something like a virtual item.

Since i am able to look into a compressed archive and copy-paste or drag-drop items out of it in explorer my guess is that getting the shell to do the dirty work of uncompressing the files to some location should be possible. Maybe faking a drag-drop could work...i will do some research into this once i get some free time to do so.

So in case anyone ever reads this and is curious about the result, i did the experimenting and as it seems the drag-drop "emulation" works, i used GetUIObjectOf[^] method to get an IDataObject for the "virtual" file inside the archive, i used the same method to get an IDropTarget for the folder i wanted to copy the file into and then i called DragEnter, DragOver (this is probably not needed) and Drop of IDropTarget, specifying the IDataObject i got and DROPEFFECT_COPY. This seems to do the job, the shell moves the file from the archive into the target folder. Thumbs Up | :thumbsup:

problem with using MUTEX events

Alan Kurlansky14-Dec-09 10:43

14-Dec-09 10:43

In my VS c++ console app i have the main thread processing input obtained by other secondary threads. The secondary threads use WaitForSingleObject to wait on either tcp input or wait to get the mutex back. These mutexes are used to control access to global buffers. Each secondary thread writes to a specific global buffer and when complete gives up the mutex. The main thread uses WaitForMultipleObjects to determine which buffer to read from, then, when done, turns the mutex back over to the secondary thread.

Problem is if the apps start up when there's a lot of data(messages) backed up I initially get a lot of reported empty buffers in the beginning and later when I get buffers they (the corresponding mutex) seem to be ignored by the main thread. This is what my log file shows. It may be that even my log file sequencing is questionable at this point.
Starting the processes like this would not be the norm but still it should all work even under these conditions.
Is it possible I have some kind of synchronization problem between the main and secondary threads? More details provided upon request.
Thanks

More information is needed in order to help you.
A common error when we use WaitForMultipleObject is the bWaitAll is not set correctly or an invalid handled is passed to the function.

Check this, if none of the above answers correspond to your issue.
