In my CDialog-derived class, I want to call a method after the dialog has been shown, with no input from the user. If I call my method from OnInitDialog, the dialog is not shown until my method returns.
I tried using PostMessage in OnInitDialog to start the method, but the message was not caught. SendMessage worked, but the dialog was not shown before the method call.
Is there a simple way to do this?

PostMessage() is the way to go. The fact that it did not work indicates the message map was not quite right.
#define PM_CHANGE_FLAT (WM_APP + 0x123)<br />
<br />
static const UINT UDM_BLOW_NOSE = ::RegisterWindowMessage(_T("UDM_BLOW_NOSE"));<br />
<br />
<br />
BEGIN_MESSAGE_MAP(CMyDlg, CDialog)<br />
ON_MESSAGE(PM_CHANGE_FLAT, ChangeFlat)<br />
ON_REGISTERED_MESSAGE(UDM_BLOW_NOSE, BlowNose)<br />
END_MESSAGE_MAP()<br />
<br />
<br />
BOOL CMyDlg::OnInitDialog() <br />
{<br />
<br />
PostMessage(UDM_BLOW_NOSE);<br />
PostMessage(PM_CHANGE_FLAT);<br />
<br />
return 0;<br />
}<br />
<br />
<br />
LRESULT CMyDlg::BlowNose( WPARAM, LPARAM )<br />
{<br />
return 0;<br />
}<br />
<br />
<br />
LRESULT CMyDlg::ChangeFlat( WPARAM, LPARAM )<br />
{<br />
return 0;<br />
}

Thanks for your quick reply
Where did CUpdateThread come from?
I would like to have my message responding method within the CDialog-derived class that is posting the message.

Hi, i need to know how to make my app check wether its connected to the internet. I need this cause my app needs to check for updates and i don't want the dial up dialog (for dial-up connections) appearing every 5 minutes. How can i stop it from popping up, so that it only checks for updates when it really is already connected to the internet?
Thanks
Kuniva

calling the InternetGetConnectedState function should not popup a dialup box.

Hi,
Im writing a program in C++, using the windows.h header file to develop an application. Im capturing images from a camera and then saving them in a default folder.
I want to allow the user to be able to browse through their file directories and choose which folder they want the images to be saved to. But, I cant find a simple solution. I would have thought there would have been a defualt control that allowed you to do this. But all the ones I have seen require you to set imagelists and things for the bitmaps to use for the folders.
I would GREATLY appreciate any help with this problem. Ive looked around on msdn, and on this site too. What is the easiest way to do it? Apart from simply asking the user to paste the folder path into a text box.
Cheers for any help

Look up SHBrowseForFolder() in MSDN Library

ShBrowseForFolder is what you are looking for, search around codeproject for samples, and/or how-to.

try this code:
BOOL BrowseForDir(char *cpPathName, HWND hParent)
{
BOOL bRetval = FALSE;
BROWSEINFO sBI;
memset(&sBI,0,sizeof(BROWSEINFO));
sBI.hwndOwner = hParent;
sBI.pidlRoot = NULL;
sBI.pszDisplayName = cpPathName;
sBI.lpszTitle = "Select the folder To Save To:";
sBI.ulFlags = BIF_RETURNONLYFSDIRS;
sBI.lpfn = NULL;
LPITEMIDLIST pidl = SHBrowseForFolder(&sBI);
if (pidl)
{
SHGetPathFromIDList(pidl,cpPathName);
bRetval = TRUE;
}
return bRetval;
}

I have found that some ADO methods (Update, Delete)
doesn't work with tables having high number of fields.
Is this problem real ??
How can I manage big tables with ADO ?
Tanks a lot !

Huh!?
Can't be...
What error do you get? Or what doesn't work exactly?

The 80004005 error is generated and the string in the exception is: "Query too complex"
This assertion is generated when I try to update an
existing record or to remove it.
Instead, when I try to add a new record and when I fill
it, or when I browse the big table, none exception is
generated !!!
I really don't know how to solve this problem !!!

Hm... don't know what i9t can be...
Are you sure that your SQL query is correct?

Rickard is right. You usually get this error when your SQL statement is wrong but you say that this doesn't happen when you add a new record, so there could be some other reasons. For instance:
1. Make table names and column names shorter.
2. Reduce the number of columns in the table.

Hi,
I have two (or more) sets of icons that I want to use together to form a combination of icons. My icons have transparency, so I want to be able to draw one on top of the other, so that the one on the bottom shows through the transparent areas of the top.
Btw, I want to be able to draw this on any dialog.
Thanks in advance.

See DrawIcon or DrawIconEx in the doc.

Hy everybody!
a little question...
I'm creating a invisible window (with create function), but when I do it my current app window loses his focus...
How can I create the window in the way that my current window don't loses his focus?

One solution is to simply focus the parent window right after calling creating the child window.

For example I have a dialog based project with tab control.
And there is some amount of dialog resources.
When I change tabs I need to include (embed) and switch those dialogs inside the main dialog.
I dig into ICQ dlls and found that they are using the same trick in dialog with tabs.
