Hello there,
Use CRichEditCtrl::SetSelectionCharFormat(CHARFORMAT2& cf ).
It allows you to change the selected text and selected background color.

Hi !!
I need to plot channels on a chart but these channels can be chosen using a pop-up menu (by clicking on the chart). The problem is that when I do this, everything is frozen and I really need to continue the acquisition and the plotting of the points.
The plotting of the points must be done in the main Thread cause I'm using the document/View architecture and I need to exchange informations between these classes.
Does anyone know how to do this ??
Thanks!

I want to beef up the appearance of my SDI appln by first poping up a welcoming window upon startup. In that window I'd have bitmaps and text. The window would show for, say, 10 secs before the main appln window. Could anyone direct me on how to create such a welcome window? Thx,
Ralf.

This is commonly known as a splash screen. You should have no problem finding an implementation (maybe even here on CP, haven't checked) on the net.
|
|
|
|
|
You can use your own Visual C++ IDE to do this:
"Project->Add to project->Components and controls", then choose "Visual C++ Components" and "splash screen".
This will do almost all the work...
hope this helps.
NOTE:
Even I know that I prefer to use some implementations that are easily found here in CP.

MSDN has a sample called SuperPAd that does this

How to show a PNG image in my dialog ? ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif) thanks

Take a look at CxImage. It's a great image processing library with support for TONS of different image formats.

Good Luck!

You may happily use GDI+ if you need, it's the Platform SDK and no third-party stuff (at least for me - a virtue).

Use libpng[^] and be more portable.

AOA!
last night as i was trying to do one of my Assignments i tried to open a form using my Class inherted from CFormView!
the problem is that i was able to show the form as i want but as i close this window using the CWnd::DestroyWindow() i get an Assert Failure!
the Code i am using to initialize the window is as follows:
//defined in MyClass.h;
CMyClass Form;
CMyMainView::OnInitialUpdate()
{
CView::OnInitialUpdate();
CRect Rect;
GetClientRect(Rect);
Form.Create(NULL,"NewForm",WS_VISIBLE|WS_BORDER|WS_CHILD,Rect,this,1234,NULL);
}
And to Destroy the Window
CMyMainView::OnFileNew()
{
Form.DestroyWindow();
}
i cant understand y i get the assert failure when i click the new button on the toolbar!
the Assert Failure Message i get is as follows:
Debug Assertion Failed!
Program:E:\Chummi.exe
File:dbgheap.c
Line:1101
Expression:_CrtIsValideHeapPointer(pUserData)
//bla bla bla

Here's my issue:
(note: this is x-posted in OS/Admin)
I'm calling an instance of IE from an NT service. If the
currently logged-on user is using a proxy server in their
profile, this setting is never seen by the instance of
the browser tht I just spawned. Starting the browser as
the correct user doesnt help either.
So, my question is: Does anyone know of a way to make
Internet Explorer read the correct user profile when I'm
spawning it? Or is everyone that uses a proxy setting
screwed if they run my software?
Thanks...

showing the screen....
Hello,
I'm creating an MFC application that does a heavy process consisting of file I/O and database handling. It's an SDI application.
The application has a modeless dialog box that informs the user about what is currently being done by it.
It works fine.
My problem is that if I minimize it while it's processing, or if I click on anohter window to do other stuff while my program processes, and then I try to show it again (clicking on it on the task bar), it won't appear until the processing is finished. But this is not what I want for two reasons:
1. it's a heavy and long processing, so the user need to be able to SEE what the program is doing, to feel that's working and not 'frozen'.
2. it's a long processing, so the user will most like do other stuff in his PC meanwhile.
So what I need is that when the user clicks on it the form appears.
How can do this?

You need to do your task in another thread. This is a large issue, but I bet that there is a lot of CP articles on threading.

Could i simply use AfxBeginThread?
Thanks

search for 'worker thread' here on cp.
Your program can show no reaction, because you never give windows a chance to process any messages.
My opinions may have changed, but not the fact that I am right.

Is there any way to solve this apart from Threads?

my pgm was using GetPixel() function, but i realize not all device support the function and that we can use GetDeviceCap() to check its RC_BITBLT capability. so though i'm not exactly sure how to use the function, i tried the following..
int test = dc->GetDeviceCaps(RASTERCAPS);
(1)It returns me a negative value(-4349)...what does this mean? What shld the function return me if my device has RC_BITBLT capability anyway?
(2)If my device doesnt have the capability, what can i do to have the capability? And what determines whether a device has the capability?
thks

|
|
|

I think it is merely:
bool bPelSupport=dc->GetDeviceCaps(RASTERCAPS)!=RC_NONE;
If your display doesn't support raster operations, then I guess
there are no pixels?  Render to an offscreen bitmap and test that
or directly test against the model from which the display is drawn.
(if it is yours)
|
|
|
|
|
bool bPelSupport=dc->GetDeviceCaps(RASTERCAPS)!=RC_NONE;
gives me compilation error...should there be a bracket somewhere?
anyway my dc is defined as below,in my CView class...so shouldnt it have pixels?..
CDC *dc=this->GetDC();
Anyway how do i render to an offscreen bitmap?
thks

You render to an offscreen bitmap by creating a memory device context for the bmp, or MemDC. You can then blt (BitBlt) to the memDC before blitting to the screen (or other DC).
Something like:
CDC MemDC;
// Get the current DC and create a compatible memDC
MemDC.CreateCompatibleDC(pDC);
// Can now Blt to the MemDC...
// Do stuff - draw, render, etc...
// Don't forget to clean up..
MemDC.SelectObject();
|
|
|
|
|
Guess it'll have to read up on that. But do you know how do i test after i've BitBlt it to offscreen bitmap?
thks
|
|
|
|
|
But if the display device doesn't support blit operations
(RASTERCAPS was RC_NONE) then he won't be able to draw
to the offscreen image and blit as the last step. He will
have to draw to both DCs instead, using the
offscreen image merely for examination.
