Hi all,
i have to Append the String Values in CListBox just Like ClistCtrl Does.
I mean i am appending the String values inside the ClistBox with some Gaps but they are not Alligned Properly.
I have to Display just like CListControl.
Code:
-----
CListBox.AddString("one"+ "-----------------" +"1"); //Equal Space Padding automatically depending on Chars in List.
CListBox.AddString("Twently"+ "-------------" +"2");
The Padding of Small and Big charters in CListBox must just appear as CListCtrl.
Give a solution for this.
Thanks,
Uday.

I am not sure I understand your question but I suspect that your CListBox is using a proportional font so individual characters are only as wide as they need to be. You probably want to use a fixed width font, such as Courier, where each character is the same width in pixels.
Just say 'NO' to evaluated arguments for diadic functions! Ash

You might take a look at SetTabStops[^] in MSDN.
Using that, you can still use proportional fonts.
Hope that helps.

Hello
I am loading an image file using gdiplus Bitmap class, and changing the transparency using ColorMatrix, and draw the image in device context, its showing fine in transparency. now i want to save this file in disk (with transparency). is there anyway to do that?
i am doing like this.
Bitmap gbmp = Bitmap::FromFile("C:\\anyimage.bmp");
ImageAttributes imgAttr;
ColorMatrix tcm =
{
1.0f, 0.0f, 0.0f, 0, 0,
0.0f, 1.0f, 0.0f, 0, 0,
0.0f, 0.0f, 1.0f, 0, 0,
0.0f, 0.0f, 0.0f, 0.6f, 0.0f,
0.0f, 0.0f, 0.0f, 0.0f, 1.0f
};
imgAttr.SetColorMatrix(&cm, Gdiplus::ColorMatrixFlagsDefault,Gdiplus::ColorAdjustTypeBitmap);
Graphics g(dc.GetSafeHdc());
g.DrawImage(gbmp, Gdiplus::Rect(0, 0, gbmp.GetWidth(), gbmp.GetHeight()), 0, 0, gbmp.GetWidth(), gbmp.GetHeight(),UnitPixel, &imgAttr);
after this, i need to save this image in disk.
Thanks
A. Gopinath.

Hi,
See Gdiplus::Image::Save() sample here[^].

Hi,
I used InternetGetConnectedState() of afxinet.h class to get the availability of internet in my application. But this clas is giving exception. If I comment this function, application is runing fine.
Is there any way to check the internet availability?
|
|
|
|
|
Could you provide more details about the exception ? Did you use your debugger to check the state of the different variables ?
|
|
|
|
|
Hi,
InternetGetConnectedState() isn't a class, it is a function inside wininet.dll and it works fine for me. Are you using it correctly? Did you read the relevant page in the MSDN documentation?
|
|
|
|
|
Before abandoning the function, you should carefully examine the exception to understand what's happening (and, as already suggested, you may post the exception message here for getting better help).

Hi All,
As u can deduce from the title, I'm using visual Studio 6.0 and i want use the Microsoft Platform SDK for some kind of project.
The main idea is that i'm new to the SDK, i download the Microsoft Platform SDK Server 2003 R2 (which is the compatible one for VS6).
I download some code from this site and when i tried to compile it, it said thjat some files were missing, such DShow.h, so i added the includes files by tools->options->directories->includes files.
now when i compile my project i've got those errors : 
--------------------Configuration: LiveVideo - Win32 Debug--------------------
Compiling...
CaptureVideo.cpp
c:\documents and settings\fst-admin\bureau\prj 3 vc 6.0\source code\capturevideo.h(115) : error C2143: syntax error : missing ';' before '*'

Error executing cl.exe.
I'm not sure if what i did was right or a big mistake, or the Microsoft Platform SDK still not recognised into my VS6.0.
So plz, some help will be appreciated.

DShow.h is in DirectShow library, and I think DirectShow is not a part of Windows SDK - 2003. Check for such a file in your SDK installed directory. I think you need to install DirectX 9.0 SDK, of which Directshow is a part, and add its include & lib paths to VS 6.0. DirectShow now comes with vista SDK and later.

Hi,
Yes indeed,, in fact i installed Direct X developper + SDK 2003 and SDK 2008. But when i use VS 6.0 it doesnt work but with VS 2005 it does. i think that the SDK 2003 doesnt includes all necessary files or the project i tried to compile is based on headers of not 2003. Any way, Thank you for your reply that was a nice hand help.

hello guys... I need to use some private function in the dll so that they might do some work for other functions that are called by original application.but im getting this error that states "illegal call of non-static member function". Here is what I am trying to do
MyDll.h
-----------
namespace MyDll
{
class MyOwnDll
{
private:
void msg();
public:
static _declspec(dllexport) double func(double a, double b);
};
}
MyDll.cpp
------------
namespace MyDll
{
void MyOwnDll::msg()
{ cout<<"The result is: ";}
void MyOwnDll::func(double a, double b)
{
msg();
cout<< a+b;
}
}
How can I do this? thnx

The message is clear: you cannot call an ordinary (i.e. not static) class method that way. Declare it as static.

This has nothing to do with a DLL or functions within a DLL. A beginners book on C++ would help you immensely though.

You already got your answer but I'll give you a quick explanation why you have this problem.
Declaring a class method as static means that the method is not called in the context of a specific class, meaning that it is very similar as a global function (it is not associated with a specific class instance). The difference between a static and a non-static method is that for a non-static method, an implicit paramater is passed to the method when it is called: the this parameter, which identifies which class instance is associated with the call (so, when you do something like that: myClass.myFunc(), the address of myClass is passed implicitely to the function). For a static method, this is not the case, since it is not associated with a specific class instance. So, within a static method, there's no accessible class instance which can be passed as the implicit this parameter passed to the non-static method. That's the reason why you can't call a non-static method from a static method (unless you call it on a class instance like this: myClass.myFunc()).

Neat, sir.

I think your explanation confuses class with an object of class, and will perhaps confuse the OP. The this parameter is a pointer to an object and does not directly identify which class is associated with the call.

You're right, I forgot an "instance" somewhere. I fixed it.

When process exit, will the memory that's left undeleted be returned to OS? My application is a C++ application.
|
|
|
|
|
Yes.
And JFYI, OS always reclaims memory after the process (application) exits. If your process runs for some time and doesn't care to release unwanted memory then it won't be reclaimed by the OS and the memory "leaks".

This part of your reply is confusing, does it mean that if I allocate memory in my program but fail to release it properly during application exit / if the application has crashed / terminated from the task manager, will this allocated memory (allocated during program execution) will not be returned to the OS and result in memory leak?
Thanx in advance
