1. I created an SDI application with Document/View support.
2. I added a COleDropTarget to the main view
COleDropTarget m_DropTarget;
3. I added this in OnCreate handler of the main view
m_DropTarget.Register(this);
It should have worked. Unfotunately, DropTarget.Register(this) returns FALSE. WHY???  Please help!!!

Is it possible to flatten multiple memory bitmaps into one device context? I just spent the whole day writing a class for layer management, where you can create as many layers as you like, then address them by name and draw to them, and when your all ready, call one function and it bitblt's all the layers into the dc of your window. The only problem is after I wrote all the code, I realized that the memory bitmaps have a black background, and when you bitblt one bitmap onto another, it just replaces what was there before. is it possible, or did I just waste my whole afternoon?

Sounds like a good candidate for TransparentBlt()

My directory always get much temporary files after compiling. I always need to pick source files (like *.cpp, *.h etc) one by one when I want to copy them to another folder or backup them. It's so pain 
Fortunately, I found a program today, it's very useful to me, maybe it's useful to you too. It can copy or clean specfied type of files and integrate with Explorer, very easy to use.
It's name is Clean Now！(http://www.liuxz.com/cleannow/index.htm) I have installed it in my computer and feel good  Usually, I develop with VC6 and C++Builder 6. So I create my own "File Group" like following:
VC 6 Source Files: dsw;dsp;cpp;c;h;hpp;def;clw;lib;opt;rc;ncb;
CBC 6 Source Files: h;hpp;cpp;c;lib;dfm;res;bpr;bpg;
Now, it's very easy to copy my source files to another folder or backup them without garbage: (1) Right click at my source folder (2)Move mouse to "Copy"->"VC 6 Source Files" (3) Select a destinition folder. After a few seconds, all source file and only source files will be copied to destinition folder. I don't need to pick them manually anymore!
If I don't want to copy them out, I just select "Clean"->"VC 6 Source Files", and HOLD SHIFT while clicking. All files EXCEPT source files will be deleted. My source folder become clear
You can try it out if you have interest

Here is another one. It also shows how to create a disk cleanup handler with source code.

hai,
In my module, i've 2 multiline edit box, 2 control buttons for send and receive,1 check box.
Here, in 1 editbox i've to give characters and by clicking send control button, store that value in a temporary variable.
By clicking receive control button, i've to display the stored value in the second edit box. Since it is a multiline edit box, all the values in the first edit box are displayed in the second edit box.
So if the check box is checked, then i should receive the values stored in the temporary variable line by line only.
Can anyone help to do it?

Yes, but what specific piece are you having trouble with? I'm assuming you've tried this on your own but are not quite getting it all to come together.
Do you have OnClick() handlers for the two buttons? Do you have a temporary variable? Are you using GetWindowText() and SetWindowText() properly? Are you getting the state of the checkbox with GetCheck()?

How can I convert a pointer to a string to a pointer to a constant string?

LPCSTR MyConstStr = (LPCSTR) MyPointerString;

No conversion is nessasary
LPSTR pSomeStr;
LPCTSTR pConstSomeStr = pSomeStr;

I have coded an expanding(growing)Array Class. After certain number of entries (Approximately 7 enters), I am unable to delete the Class. I get Debug Assertion Failed (_BLOCK_TYPE_IS_VALID).
I hope someone can help me...

Maybe if you post some source code...
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

I have an icon in the system tray for my app to keep it running without showing in the taskbar. However, for whatever reason, my explorer (explorer.exe) crashes every once in a while, then refreshes. When it does this, the icon for my app is gone from the system tray, but others like SQL Server and various other apps I have running refresh themselves. Does anyone know how they do this, or better yet, how I can?

See this MSDN page on the taskbar[^] and search for "TaskbarCreated". That section tells you what do to (basically you just handle a registered message and re-add your tray icon).

Hi there,
I'm having trouble upgrading my VC++ 6.0 to a .NET compiler (manually of course). I recently installed the free Visual C++ .NET 2003 toolkit from the Microsoft Web-site (they don't provide tech support for the toolkit). It's a command-line C++.NET compiler. I'm trying to integrate it into the VC++ 6.0. How do I do this?
Thanks

Specify the directory in the the options, directory page under Executables. Make sure the path to the new compiler is above the path to the old one.
Note that the VC++6 debugger does not support the debug information generated by the new compiler, so you won't be able to use the integrated debugger to debug programs compiled with the new compiler.

Hi, all,
I built a C++ dll which contains functions accessing database using OLEDB. I try to load the dll functions from Access VBA. I can successfully execute non-db functions in the dll. I can also successfully execute open/close connections to db functions. But I have troubles to open a recordset with a sql statement after open the connection to db. Everytime it gives several error messages saying "The instruction at xxxx referenced memory at xxxx. The memory could not be read". Does anyone has any idea what may cause this? Or does anyone has a successful example?
Thanks!

Hello,
I just finished a project of mine. Since I like the result, I would like to build the functionality into Visual Studio 6.0.
I searched the internet (codeproject, codeguru, msdn and google), but I found no relevant information.
If somebody might know an article, sdk or an other resource where I could find the information needed to build a com add-in, please link me to that information.
Thanks in advance.

I want to create my own function like the Win32 API's, where you can use things like this: WS_VISBLE | WS_BORDER.
What opperator do I use to check for each style? and what variable type should I use? I'm guessing LONG or WORD
Winuser.h makes everything this way: #define SOMETHING 0x10000000L.
So if I want 14 Flags, what should I make each one?
while I'm asking about opperators, here is some code that always executes no matter what style (it seems)
LONG Style = 0;
if((Style = GetWindowLong(hwnd,GWL_STYLE)) != 0){
if(!(Style & BS_TEXT)) {
SetWindowLong(hwnd,GWL_STYLE,Style & ~BS_BITMAP); if((Style = GetWindowLong(hwnd,GWL_STYLE)) != 0) SetWindowLong(hwnd,GWL_STYLE,Style | BS_TEXT); }
}
