We all use some sort of printf or CString::Format in the code, we are not careful sometimes. So how to handle this problem or check out the bugs in the exist project?
I've had some bugs due to wrong usage of sscanf and fscanf. VC6 didn't report stack corruption errors but VC8 does! Here is a blog post on these bugs, hope this helps!

I like printf, sprintf and other functions but at we times use these in a wrong way resulting in bugs. Reading the docs carefully, again carefully, "on the format specifiers to be used for different types" will help a lot in solving and finding these bugs!
Just now found one bug with the usage of the TRACE macro. One of the trace messages contained a '%' sign resulting in application disappearance. AtlTrace treats the first argument given as a format specifier IMO hence the bug. Replaced TRACE with TRACE0 macro and now it's fine.

Being careful.

|

use GetModuleFileName;
code like:
TCHAR szPathBuf[MAX_PATH] = {0};
GetModuleFileName(NULL, szPathBuf, MAX_PATH);
then the buffer 'szPathBuf' contains the full path including the exe file name.
you can printf the buffer to see it.
you may need _tsplitpath too.
include the needed header files. and add the needed libs!

Hello,
Here is the issue.
I have a win32 dialog on which there are some controls and I have call back method defined for handling the messages. One of the control is a button. Once the button is clicked and released, WM_COMMAND is received by the call back method. But as i need to handle button click and button release messages seperately i used Subclassing. I defined one more call back method for this button and now i am able to receive button down and button up messages.
There is a shortcut assigned to this button. On pressing the shortcut key, WM_COMMAND is received by the window call back but not the control call back. On releasing no message is sent to any of the call backs. Is there a way to enable the framework to send appropriate message to the control call back...
Please let me know if you need more details.
Thanks in advance,
Hari krishna.

you mean Lbuttondown and LbuttonUp ?? Its better to handle the BM_CLICK message. It will be fired in all cases.

Thanks Naveen for your reply. I need any sort of message to the control call back on pressing the shortcut key and also on the release of the same. Right now it goes to the dialog call back as WM_COMMAND once the shortcut key is pressed.

Did you try handling BM_CLICK message in the button's call back function..?

Hi Experts,
I have a CListCtrl with LVS_EX_CHECKBOXES style but if I check/uncheck the item from list how can get the index of it?
I also used LVN_ITEMCHANGED and NM_CLICK but could not get the selected item index.

Have you had a look at the dozens of CodeProject Articles about using CListCtrl?

I have never used MSXML, so bear with me. I have a small C++ app that receives a message via another app. The message received is XML format but is contained in a string and not passed as an XML doc. Stuck with this, nothing I can do about this part.
So, I need to implement MSXML, I am hoping this is the right path, to load the string into an XML doc and parse through it. Does anyone have or know of a simple example of how to do this? The xml string I receive only has 2 elements, so this does not have to be a very involved example with lots of bells and whistles. Just looking for the basics.
BTW, I am using MSXML 6.0.
Thanks a lot in advance for the help.

MSXML implements an XML DOM and maybe also a SAX parser. You can go study how those things work at web sites like TOP XML and www.w3schools.com
I also believe you will find sample code using MSXML at w3schools. Now those samples might be in something like Javascript but that doesn't matter because the COM interfaces are the same when you use them from C++. Of course if you don't have experience using COM interfaces from C++ then you will also need to learn about that.

When the cursor stays on an icon(i.e. an icon of a folder or an application), how can i get the message that there is a folder under the cursor? Just like the tooltip, when the cursor stays on an icon, it appears. I want to accomplish the same function.
