For those new to message boards please try to follow a few simple rules when posting your question.- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- If you are posting source code with your question, place it inside <pre></pre> tags, or click the "Ignore HTML tags in this message" check box.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.

1, The best way is sniffer, download the WinPcap http://www.winpcap.org/[^], and look at the samples.
2. Hoot the network api, such as send sendto etc. download M$ detours , look into the sample which hooks the network api.

| Unhandled exception when exiting application??? | | llp00na | 2hrs 51mins ago |
|

I have created an MFC application, dialog based. The application contains 4 child dialogs. and everything was fine.
Now I tried to create a 5th dialog box. The program compiled and ran fine but when i try to close the main dialog window I receive:
Unhandled exception at 0x7c22c81a (mfc71d.dll)
The Call Stack refers to the InitDialog?

Hi ,
Wanted to know if all the handlers for the child windows are correctly returning the value.
Is the 5th dialog box having some extra code , or is it not returning the value which it is supposed to .

In the old days, there was a very nice function called DlgDirList (and DlgDirListComboBox) which filled a listbox / combobox with the files in a directory.
But there is no equivalent for a Tree Control, sorry.
You need to combine two bits of knowledge:
1/ FindFirstFile / FindNextFile to loop through all the files in a directory that match (eg) "*.txt".
FindFirstFile has a decent bit of code sample in its documentation that will be better than anything I can quickly type.
2/ And CTreeCtrl::InsertItem to put those items in the tree.
Lastly, download my article: http://www.codeproject.com/KB/system/Drive_Detect.aspx[^], and look in the code. It has code to construct an imagelist with the pictures for the different drives in it. This stage is optional, but little pretty pictures never hurt!
Good luck,

Use FindFirstFile/FindNextFile api's to get the content of the folder. You can check using WIN32_FIND_DATA if the specific object is a file or a folder.

You know, CodeProject has a whole section of articles on tree-controls[^], including this one[^].
Do try and show some initiative. You managed to find this site - searching it and finding that article would have been the ideal next step...

| How to replace/change the container menu item and menu item behaviour from an activex control | | Member 4361455 | 4hrs 55mins ago |
|
|
Hi All,
I have inserted a "Adobe Acrobat Reader activex control" into my "mfc activex control" project, so that I can use it instead of adobe's default activex to view pdf files in internet explorer.
Now, when the Acrobat activex loads in internet explorer, the file menu gets modified. Typically, the "Print" option is modified in such a way that it calls the acrobat reader's print dialog box.
I want to have my activex control override the default File menu behaviour of Internet Explorer just like the acrobat reader control does. Why I would want to do this is to be able to discard the original (Internet Explorer's) Print message and call the inserted acrobat reader's Print function (or any other similar function present in the control).
After much attempts at trying to find relevant documentation, I could not find anything that would be of much use  . Can anyone please point me out to either some similar document/link where such an example has been elaborated.
Many thanks in advance...

| A dialog with button controls does not have focus OnKeyDown | | AglaiaMasaki | 5hrs 15mins ago |
|
|
|
|

If you read the documentation of CDialog::OnInitDialog[^], you find this:
Return Value
Specifies whether the application has set the input focus to one of the controls in the dialog box. If OnInitDialog returns nonzero, Windows sets the input focus to the first control in the dialog box. The application can return 0 only if it has explicitly set the input focus to one of the controls in the dialog box.
So return FALSE from OnInitDialog. Does that help?

I tried and the button control seemed losing its 'focus', but when I pressed spacebar, the button was still clicked.
(The problem is that my action(pressing the key) didn't call the OnKeyDown function because of the buttons.
Once I removed the buttons for test, the program worked well. Yet I have to add buttons.)
Anyway, thanks for your answer. If you have any ideas, please let me know.
May the sky bring you a full measure of health and prosperity.

I'm not sure but you could try catching the key press in the PreTranslateMessage[^] method of the CDialog...
