Thanks guys... i manage to write the program in JAVA since i did socket programming in JAVA before.... i will try to work on this first.. once its could be done as i wanted, then i will do it with C++ since i wanted the program to be in C++ 
Thanks a lot with your ideas and suggestions... It was all about socket to connect to IRC... never know it will be easy as this.... Really helped me..

hi all,
i have a value like this in my application..
CString strTemp = "hello world";
now, i want the word "world" to be disabled(grayed out..) like wat appear in a static text box..
is it possible?
Thanks,
Rakesh.

CString class holds just a string (array of characters). It doesn't have any color information associated with it.
|
|
|
|
|
How are you displaying the string ? As already mentioned by somebody else, CString is just a class containing data and doesn't have any relation with how it will displayed.
|
|
|
|
|
What you want is a different color for a word.
You can only disable/enable windows and not words.
Also as Rejeesh said, you cannot do that with a CString alone.
You could use a control similar to a rich edit control and show one word with a different color.

|
|
|
If you are using the string in pDC->TextOut (...) you can do it as well by changing the font color, but you can't do it only depending on words, you will need different strings, so you print one, change the color and then print the next.
this[^] or this[^]may be useful for you as well.
Regards.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpfull answers is nice, but saying thanks can be even nicer.

Sorry, but that isn't possible.
Kindly buy and read a beginner level book on Windows programming.

One way to store colour information in a CString is to use HTML tags and then dump the string into a HTML enabled control.
-or-
Use RTF codes and dump into a Rich Edit Control.

Another way to store color information in a CString:
CString strBackground = "Blue";

Good point.
Another method:
CString strBackground = "Blue";
|
|
|
|
|
CString strBackground = "█";

Im using following code to reduce the dialog width.it show assertion error
void CToolTab::ReduceWidth()
{
this->SetWindowPos(&CWnd::wndBottom,0,80,100,800,SWP_NOSIZE);
}
assertion error in bolded line
BOOL CWnd::SetWindowPos(const CWnd* pWndInsertAfter, int x, int y, int cx,
int cy, UINT nFlags)
{
ASSERT(::IsWindow(m_hWnd) || (m_pCtrlSite != NULL));
Here m_hWnd shows 0x0000.
Im reducing the width after pressing button in the same dialog.

From which function are you calling ReduceWidth()?
|
|
|
|
|
I believe you're calling SetWindowPos in a place where the window has not been created yet.
Is it in the WM_SIZE handler?
Add a condition before you call SetWindowPos.
if (::IsWindow(this->m_hWnd))
this->SetWindowPos(&CWnd::wndBottom,0,80,100,800,SWP_NOSIZE);

actually im using WPF C# dll in vc++ code.
In that dll i have button ,so the button handler calls collapse() delgate fucntion.
in VC++ im coding like
Tabcontrol::ToolBar::Collapse += gcnew Tabcontrol::ToolBar::Navigation(OnCollapse);
void OnCollapse()
{
CToolTab tab;
tab.ReduceWidth();
}
void CToolTab::ReduceWidth()
{
if (::IsWindow(this->m_hWnd))
this->SetWindowPos(&CWnd::wndBottom,0,80,100,800,SWP_NOSIZE);
}
But my cursor get out form the IsWindow linw.Because m_hWnd shows 0x0000.
Then how can i use this SetWindowPos?
In OnInitDialog im using SetWidnowPos as follow
SetWindowPos(&CWnd::wndBottom,0,80,300,800,SWP_SHOWWINDOW);

'tab' variable in OnCollapse() is local to OnCollapse(). The 'tab' variable will get destroyed after OnCollapse() call.
|
|
|
|
|
By declaring CToolTab globally,its not working.

Please help with this code.Am trying to design a Matrix class with the following operation Addition, Multiplication, Subtraction and division.The code compile , But my result is incorrect
.please if someone can to solve this incorrect result.
This is my code Below.
#include <iostream>
using namespace std;
//member function of matrix class
class matrix{
public:
matrix();
matrix(int m,int n);
int getRow();
int getCol();
double& operator()(int, int);

matrix operator / (matrix&);

Hey Richard, this is just a repost. Please avoid doing it.
Someone already answered your question. Your code is a bit messy and it looks like you haven't a clear idea about matrix multiplication and division.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Did you even read the replies you got from your previous question ? Your post was wrong on so many points, now you can add "Reposting is bad" to the list.

"The code compile , But my result is incorrect"
When this happens, the Toy Problem debugging pattern is appropriate: Run your code on the simplest problem possible, so you can look at values in the debugger and figure out what you're doing wrong.
In your application, try working with 2x2 matrices. Step through your code and see where it's doing something wrong.

Hi,
I am loading a 32 bit bitmap (24 bit + alpha channel) into a CImageList and then attempting to draw it without much success. The 'transparent' bits are drawn in black. If I specify black as the mask when I add the bitmap it works OK but this means I cant have any black pixels in the bitmap.
Does anyone know what is needed to make this work. For info, I am dioing the following...
Loading the bitmap...
HBITMAP hBM = (HBITMAP)::LoadImage(AfxGetInstanceHandle(), s,
IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
if(hBM)
{
BITMAP bmp;
::GetObject(hBM, sizeof(bmp), &bmp);
UINT flags;
switch(bmp.bmBitsPixel)
{
case 4:
flags = ILC_COLOR4;
break;
case 8:
flags = ILC_COLOR8;
break;
case 16:
flags = ILC_COLOR16;
break;
case 24:
flags = ILC_COLOR24;
break;
case 32:
flags = ILC_COLOR32;
break;
}
m_imageList.DeleteImageList();
m_nImageWidth = bmp.bmWidth / m_nStates / m_nStyles;
m_nImageHeight = bmp.bmHeight;
m_imageList.Create(m_nImageWidth, m_nImageHeight, flags | ILC_MASK, m_nStates * m_nStyles, 0);
CBitmap bm;
m_bImageLoaded = true;
bm.Attach(hBM);
m_imageList.Add(&bm, RGB(255,0,255));
And drawing...
if(m_bImageLoaded)
{
m_imageList.Draw(pDC, nImage, loc, ILD_NORMAL);
}
Thanks
Tony

If you want black pixels in your transparent bitmap, you could change the alpha channels to any of the other 16 million colors and specify that as the mask color.
|
|
|
|
|
It's been a while and I've to scrounge up the code, but I believe you have to use a flag of ILC_COLOR32 and 32-bit bitmap must be a DIB section.
|
|
|
|
|
32 bit bitmap in imagelist is only supported in common control 6 and above. so please enure you are using common control versio 6 or later.
