HDC hdc = ::GetWindowDC(NULL); int l = image.DrawString(hdc, x, y, "ch",c, "Arial");<br />
::ReleaseDC(NULL,hdc);
what exactly the line GetWindowDC(NULL) does. and what happens when we place the hdc in the Drawstring(hdc,..).

Analyzing the source of CxImage library (ximawnd.cpp), it seems the HDC value is used to format and draw the text on a temporary in-memory bitmap, and then the image is copied from this bitmap to CxImage object.
It does not look much optimized for speed, and maybe you will have time to investigate some other approaches, like creating your own HBITMAP object, drawing on it, and then saving it to a file, for example using CImage class from ATL/MFC?

Is the keyword 'void' a datatype?
|
|
|
|
|
Pointers can also be declared as void. They can't be dereferenced without explicit casting. This is because the compiler can't determine the size of the object the pointer points to. For example,
int x;
float f;
void *p = &x; // p points to x
*(int*)p = 2;
p = &r; // p points to r
*(float*)p = 1.1;
Answer your question?

Its more of an anti-datatype. When used by itself (e.g. as a return value for a function) it means there is nothing coming back. When used as a pointer (void*) it means it is pointing to an address in memory, but you either don't know what datatype it is, or don't care what type it is (that is, that you are just concerned with the bytes that start at that address, and not the actual datatype that is there).

Read the lines in the list control, one by one.
For each line, split it into it's parts (name, city, country)
Compare the name from the list with the given name. If it matches, compare the city (from the list) with the given city. If it matches, display the country (from the list).
What's the problem?

|
|
|

you can give an example how can i do this !?
PLEASE !
Thank you !

Sorry, I don't have the time right now.
But there *is* (for sure) a lot of examples how to:
1. Find out the number of used rows in a list control.
2. Get the text from a specific line in a list control.
That's a good way to start.
When you got that logic working, continue with splitting a text line into it's components (in your case, name, city and country).
When that's done, go on with the comparison.
And you are done.
A hint: Study the methods of the CListCtrl class.

For sure, I won't try to answer his questions again. He won't give up until someone else presents him a complete, running sample. He won't ever be a coder with that attitude.

And after reading all your posts I need a good strong stiff drink. Geez, have patience!

You've only waited 16 minutes.  Why are you so impatient? Do you think asking the same question in a 4-5 hour window will actually get you any useful help? Any chance you had is surely gone by now.

Yet another useless subject line. By now I would have expected you to have read the forum rules to discover why you are not getting a response that you can use. Perhaps you should stop whining too.

Can't you wait any longer than 57 minutes?

Hi all,
I'm struggling with a strange problem. The thing is I wrote a application that installs / creates a DSN. I'm using a dll called Interop.ODBCTool.2.0.dll. And this dll has a function called CreateDSN() which accepts the following parameters:
- DSNname
- ODBCDriver
- Server Name
- Database Name
- Username
- Password
- Silent Option (bool)
- ODBC ATT (parameter can be NULL)
So the problem is that, I can create a DSN on a machine that has a established MySQL installation (that has other datasources, databases and so on.) But when I install a fresh copy of MySQL on a machine and nothing has been done concerning DSN, Databases and so on, the function (which is bool) returns false. It doesn't want to create a DSN. (But ... Like on my machine it works fine) . So the thing is do you have any idea that the problem could be.
(The MySQL Drivers is installed)
Thanx alot.
