I don't exacly get your point. Do you have all child dialogs visible at the same time, or is it DoModal() for each child dialog?
If you are using DoModal() for each child, then get the data from each of them:
CChild c;
if (c.DoModal() == IDOK)
{
int a = c.m_Variable; //Do this for all variables you need.
...
}
this is this.

What you need to do is string-processing, not some filing technique.
I hope it works.
this is this.

Why? What problem(s) are you having?

hello...
supposed you have two bitmap images in your form, say bitmap1 and bitmap2... how can you get the difference(image subtraction) of the two images...
thank u in advanced....
|
|
|
|
|
First, you need to get the dimensions of the bitmaps, then allocate an appropriate array (wid*hei*bpp/8 bytes). Use the GetBitmapBits function to populate the array. Do the same with the second array. Subtract them byte by byte. Use the SetBitmapBits to fill the CBitmap.

I want to have a reset button on my dialog box which restore the control values to their original values.Any clue which function shud I call in the reset button function??
|
|
|
|
|
I usually keep the default values in a config file..then read in from the file and update to the control values. Not sure if this is the best method.

I'd store the default values in an XML file that you'd load at the beginning
and then you'll have to reset each component one by one. The best automated thing you can do is to group all the edit box to have their resource id consequtive so the you'll be able to do in case you want to reset them:
for(int i = iFirstResId; i <= iLastResId; i++)
SetDlgItemText(i, "");

Or use the UpdateData function sending in the right parameter (I can never remember if it's TRUE or FALSE). As long as you haven't called it yet to update the variables, calling it with the right parameter will put whatever the variables' value are back in the controls

If you've designed it properly, my suggestion would be to simply click the Cancel button and then open the dialog up again. All of the initial (default) values will be present at that point and you will not have had to resort to some "reset" button.

How do i maintain the focus in a edit box? For example i was typing half-way in the edit box, however an event occur and the focus got changed. How do i set the focus to remain in the edit box.
This is wat i tried to do when the event occurs
<br />
if(m_alarmOn==false)<br />
{ <br />
m_alarmOn= true;<br />
<br />
CWnd* prev = this->SetFocus();<br />
prev->SetFocus();<br />
<br />
CreateThread(0,NULL,CSecurityDlg::playSound,this,0,0);<br />
}<br />
<br />
The above code reside in a OnBtnClick function. So when alarm is on, the button will be auto click....and the alarm sound goes off....
But in the process of these, i might be typing in a editbox. So i will lose the focus...How do i get it to stay?

Tks. I resolved it using pic control and defining a WM_action message instead. Thought this would be neater.

How do i include a header files directory of another library to my project's include file path.
|
|
|
|
|
Open the project settings.
Go to the C++ tab.
Use the combobox to go to the Preprocessor entry.
Under 'additional include folder' enter a relative or absolute path.
I prefer to use relative paths from the DSW file, since I might end up with a different drive letter or arrange items into different levels. Less work if things are relocated relatively to each other than a hard coded path to some specific drive in some specific rooted folder hierarchy.

Suppose im using an open source library borZoi-1.0.2.I copy its folder to my project and the header files r in

Hi all,
While i use
CreateProcess(
LPCWSTR pszImageName,
LPCWSTR pszCmdLine,
LPSECURITY_ATTRIBUTES psaProcess,
LPSECURITY_ATTRIBUTES psaThread,
BOOL fInheritHandles,
DWORD fdwCreate,
LPVOID pvEnvironment,
LPWSTR pszCurDir,
LPSTARTUPINFOW psiStartInfo,
LPPROCESS_INFORMATION pProcInfo
);
I want to pass a structure as second parameter(pszCmdLine) in this function. But somehow child process can't correctly get the structure! Should i do anything like "cast" or.. before i pass it? thanks for any advice!
