Hi
I just installed STLPort on my system, and I find it superior to Dinkumware's implementation of STL. However, I am now building a library that will be used by a lot of users, and not all of them have STLPort on their system. Is there a way that I can build my library and still make it usable on all systems?
Thanks!

Any STL implimentation is going to be in the form of code that you include. So it's already in your program, the compiler puts it there.

Hi
I wanna capture the desktop and save it to a jpg file, I know how to save it to a bmp file uncompressed but that file is to large 3 megs!!.
So I try to modify the code for capturing to an bmp
and I can not view the jpgs I create
what is wrong?
where am I wrong
here is the code:
[code]

Dad, how strange it is that the pig can speak.
*thoughtful pause* It must have lost its "oink".

anyone any ideas why a slider that increased values as it moved left to right now decreases as the slider is moved from bottom to top? I just changed it from horizontal to vertical through the properties box under msdv6.......shouldnt it increase as the slider is moved up?
cant find an option to rotate/flip it.

If it works anything like a spin button control, the arrows will act reversed until you set the range over which the control is suppost to work after that they should be the correct way up.
Try using the SetRange() function. Also try swapping over the min/max values
If you vote me down, my score will only get lower

Hi I'm kinda new so i'm sorry if i'm ask this in the wrong forum.
I would like to know if it's possible to get the processID of a process that has terminated another process.
Is it possible to get this ID in the process that is (going to be) terminated and/or is it possible to get the ID from a third process that is running at that time.
I searched on Google already, i searched on the MSDN @ MS online, and ofcourse on The Code Project, but I couldn't find anything useful 
Although i must say, i find it a hard subject to make a good search on.
Tnx

Sorry, how did you expect this code to save a jpg ?
The best and easiest way is to use GDI+.

In answer to your email, my articles on GDI+ are not the only ones here that will show you have to save a jpg with GDI+.

I am planning to use Named Events to provide a scripting interface to my application.
The scripting DLL would fire these Events, say Check box 1 checked etc.
My question is how many Named Events can an application deal with without any problems.
i.e. 1 ~10; 10 ~100; 100 ~ 500 etc.
I thought that Events would provide a nice clean interface; rather than using memory mapped files/mutux protected etc.
Any comments?

You can make hundreds, but you have to ask yourself, would you want to?
You can only wait on, I think, 32 at a time with WaitForMultipleObjects, so having so many events might not be a good solution to your design problem.
It might be better to have a few in several classes, like 'data ready' and 'abort' and a few others. Then find some scheme to generate a queue that you can put command or data items into to be read by your 'processor' when a particular event is set.
If you want to proivde a scripting interface to your application, can't you just embed visual basic for applications, make an OLE Automation Interface, or implement local RPC calls for example?

How to develop a program to receive file from mobile phone to pocket pc 2003?

Hi,
I want to have multiline items in my CTreeCtrl. Therefore I use Custom Draw and the drawing works perfect!
but I have 2 issues:
First I have to know how I can draw the ExpandBox (the box with + and -) left of the Treeitems. Is there any API-function or do I have to create an icon and draw it by myself?
The next issue is related to the position of the rootlines. How can I get the coordinates of the rootlines?
Has somebody of you done this yet? Or do you know some good links?
|
|
|
|
|
I did something similiar to what you need in this article which handles the printing of a tree control. It shouldn't be too hard to modify it to do what you need. I handled the special +/- | icons by using GDI to draw them (not too good but ok for printer). I have been thinking of changing these to icons in an image list and handling the drawing of them the same way as the item icons.
Anyway, here is the link Tree control print[^]
If you vote me down, my score will only get lower

I went through the example code for text to speech conversion. I actually need to pass the text to that program by selectin text from Internet Explorer and then passing it to the VC++ application by some custom built button or right click option.
I'll be greatful if anyone helps me out.

Hello!
I need to change the background of a tab control. I can change the background of the tab windows, but I don't know how to change the background of the surrounding frame, keeping the lines that give the frame-like look.
Does anyone know how to do that?
Thanks in advance.

I'm new C++ learner.
Now I have to convert DIALOG style of the source code into MDI.
Could any expert tell me how to do?
thanks a lot.
|
|
|
|
|
It's a very long task.... what I would do is to use AppWizard to create the MDI application skeleton. Then copy the relevant code from the dialog based application to the new generated one.

If by "snapshot" you mean capture its bitmap to the clipboard, you might want to try this:/ravi
