Hi Guys,
Can anyone guide me to check whether particular application is been installed on my machine or not thorugh coding (may be Windows API or MFC).
Thanks in advance.

Try getting the installed applications list through the registry.
Check HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

This registry key holds some information ( Start->Run fetches commands from here )
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
This registry key also holds information on installed applications ("Open with" dialog fetches application names from here).
HKEY_CLASSES_ROOT\Applications

Short of searching the entire disk(s), there's no sure-fire way of finding such information. You could look in places like HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths, but those are only as good as the applications themselves. An application is not required to update those registry keys.

Hallo,
Does anyone here know an easy way to change the text of the header of a listCtrl. Till now, I delete all columns and insert them with the new text again. But I think, there should be an easier way
Thanks, Gerhard

Use SetColumn.
An Eg:
LVCOLUMN lvCol = { 0 };
lvCol.mask = LVCF_TEXT;
lvCol.pszText = _T( "Nibu babu thomas" );
SetColumn( 0, &lvCol );

Thank's for the example - my text is stored in a CString. And with this it doesn't work (conversion to string doesn't help).
But it works with a code like this:
<br />
char othertext[100];<br />
sprintf(othertext, "%s", text);<br />
lvc.pszText = othertext;<br />
Am I crazy to do so????

Yes!!
What about...
lvc.pszText = text;
Either way text is a string right?
Well if you have want to have strings that contain number then it's quite ok...
sprintf( othertext, "Column number: %d", 1 );
lvc.pszText = othertext;

Maybe my part of code was too short so I send the whole loop
<br />
LVCOLUMN lvc;<br />
CString titel;<br />
int i = 3;<br />
if (kstkaranz->wdfirst())<br />
do<br />
{<br />
i++;<br />
titel = kstkaranz->wdgetkstnr() + "\n";<br />
titel = titel + gettitel(0, kstkaranz->wdgetdatenart(), kstkaranz->wdgetvon(), kstkaranz->wdgetbis());<br />
listCtrl.GetColumn(i, &lvc);<br />
char strbetrag[100];<br />
<br />
sprintf(strbetrag, "%s", titel);<br />
lvc.pszText = strbetrag;<br />
listCtrl.SetColumn(i, &lvc);<br />
}<br />
while(kstkaranz->wdnext());<br />
where kstkaranz->wdgetkstnr = something like "6984" (number of a cost center) and the result of gettitle is something like " PLAN VALUES 2007-01-01 - 2007-02-28'. The whole result in titel is a CString (with numbers, of course, but handled as CString).
Btw, it works fine and as there should be no difference, whatever the CString titel contains, I see no danger. But your posting made me consider ....??
Btw2: if I try "lvc.pszText = titel;" I get an error-message like (I try to translate): Binary operator: no operator defined who accepts a right-sided operator of type 'class CString'

Your code is fine. But your code snippet made me say that.
There is no point in sprintfING another string into another string. Since we already have a string it should be fine.
You can assign a CString object into lvc.pszText, do this...
lvc.pszText = titlel.GetBuffer(0);<br />
titlel.ReleaseBuffer();

Hey, this seems to become a fine weekend. I'm just having breakfase (it's 8:00 here), want to read some newspapers in the internet - and the first when I look on my monitor is your message. Of course I tried suddenly and it works!
Btw - with ' 'why I'm wrong ' I wanted to say 'why I made something wrong in my code'. My english
So, many thanks and have a nice weekend too

The reason is you could have used "title" directly instead of trasferring it into another string. Does such a copy satisfy any purpose.
None AFAIK. It will be a performance hit. It's redundant that's why I said you are wrong.

I tried your code but now all my columns say "Nibu babu thomas"
Just kidding

Of course you don't, no one does. It never happens. It's a dumb question... skip it."

No problem, if I can say "nibu babu thomas - PLAN Values" and son on
But indead, his answer helped me very much. I don't know, why he said I'm wrong
No problem, it works

ensger wrote: I don't know, why he said I'm wrong
I said that from your code snippet.
Look at the following example...
char title1[100];
sprintf( title, "%s", aString );
What's the point in doing this!!!. Since aString is already a string why not directly assign that string in a proper way and also on the long run this could be a performance hit.

Hello, brother/friends in this codeproject.com forum.
first, My Name is Pardi Banjarnahor, I come from Indonesia.
as an information, my background aducation is in electronics.
the matter is I have a plan to make a program (software) that make possible for chatting (a client server application). May be it is like a SIMPLE yahoo messenger.
May questions are:
1. what kind of compiler (software) that is better, off course easy (simple) to make that sofware ( a client-server application).
2. it's possible to create/program it using MFC in Visual C++ 6.0?
3. I'm still a beginner in C++ programming, but I'm longing to be a good programmer in C++. If any one of you have information or advise (suggestion), It'll be very useful for me. if it's possible for you, you can e-mail me through Pardi.Marbun@gmail.com
Thanks for your attention and help.
Best Regards,
Thanks and GBU
