I hear you. I can make small timers, kill them and do 'settimer' repeatedly, but then being a lazy programmer - was thinking of skipping them and just have a one-shot timer

Counting isn't an option for you, is it?

You can store datetime when application starts. Set some timer interval and read cureent time each time when receive WM_TIMER message. If the difference between application starting time and current time matches your requirement, take desired action.

I have a dialog based application.In this I have a button which takes the value in a textbox and adds it to a combobox.I have to enter values in three textboxes.All these values have to be written into a file.
I have writen the code as follows:
GetDlgItemText(IDC_EDIT1,str1);<br />
GetDlgItemText(IDC_EDIT1,str2);<br />
GetDlgItemText(IDC_EDIT1,str3);<br />
fstream f;<br />
f.open("myfile.txt",ios::in|ios::out);<br />
f.write(str1,str1.length());
When i open the file to view the contents,its not written properly.Also I want to append the details each time I enter values in the textboxes.

How str1, str2, str3 are declared.
What values were assigned to such variables?
What is written inside the file, insted?

All of str1,str2 and str3 are CString variables.the str3 im using is the name of a camera.appending is not done properly.file contents are not written properly...

How can we help you if you are so reluctant to provide meaningful info?

You wrote only the first string. What isnt properly?
Read the docs to fstream. This is really beginners stuff.

try this
change the fopen as
f.open(myfile.txt",ios::in|ios::out|ios::app);

You better write "MSXML2.DOMDocument.2.0"
is MSXML4.dll correctly installed?

I want to create a List Control with ComboBox and Progress Bar in CListCtrl subitem.
Thanks in Advance.

Well, you have two completely different questions there.
If you look in the Button section of articles, you'll find a bunch of pretty buttons with a drop down arrow just like combo boxes. Then you can monitor for the "I've been clicked!" message, and show a List Control if you so wish.
As for showing a progress bar in a List Ctrl, there's an article under the List Control section called "List Control Extended for Progress Control". I can't think how searching could find you a better option.
It's all on here [*] if you look for it!
Iain.
[*] OK, not *all*, but lots...
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

In windows vista, whenever windows security requires your permission to do something, it pops up a dialog box asking whether to allow/cancel, and everything on the screen behind the dialog box becomes dark. It is like the rest of the screen has a black tinted glass over it and only that dialog is bright and shiny in the middle. How do I replicate this behavior with a popup in visual c++ with MFC ?? If you could recommend some API or link me to an article you know of on the topic it would be great. I am using VS2008 if that matters.

When ever a UAC dialog is displayed in vista, it takes screeshot of the current desktop, then creates another desktop with that image in the background. That means, they apply the effect to the image they captured from the original desktop.
