Hello,
I have a 2 CRichEditCtrl boxes on a CMDIChildWnd for which I want to set the Caret position.
I am handling KeyUp and KeyDown messages to track if a left or right arrow is pressed.If a right arrow is pressed in the first box and the cursor is on the last character then I move to next box.all this is working fine.
But the cursor goes at the end of the string for the next window.I want to place the cursor to the first character of the next window .I can place the cursor by SetCaretPos() but when a charater is typed the character gets typed at the end of the string.That is the cursor position has changed but the behaviour has not changed.
What should be done ? I want to change the cursor position alongwith the behaviour.
Regards
Pritha

Did you try using SetCursorPos()

You should let the control take care of the caret.
I believe you need to use CRichEditCtrl::SetSel(0,0) to move the
caret/insertion point where you want it.

Using LoadLibrary() or CoCreateInstance() depending on what you have and how do you want to do this.

Please someone tell me how to use properties file in my program.
i.e. how can the values related to each key can be called in the program. And by which functions.
Thanks.

May be this question has been asked earlier. What is the format of your properties file? Since you talk about the key in your query, is the file in XML Format?

The format is somthing similar as below..
file_name=file
max_no_of_files=10
level=max
I would also like to ask, is there any particular format for putting down the properties files for use in C++?
|

I think you need to extract the string using some delimiter. If you have the strings or the key-value pair on separate lines you can read the full line and then extract the key and the value based on "=" delimiter.
A proper way of writing down the entries, would be a XML file. You can find that lot of applications do use the XML file in the config format.
If you have lesser number of entries and you are allowed to read/write from registry you can also go for this easier option, but this depends on the privileges you have as a developer.

That looks like old .INI file format - you can use the
WritePrivateProfileString()/GetPrivateProfileString()
functions to work with INI files.
Using XML is a more modern and flexible approach.

That's up to you and your program. It matters not that you call it a properties file, an initialization file, or an options file. What's in it is only relevant to your application.
Now, what exactly are you wanting to do with this file (i.e., what purpose does it serve)?

Ok. I was given
ULONG dwToken;
Gdiplus::GdiplusStartupInput input;
Gdiplus::GdiplusStartupOutput output;
Gdiplus::Status status = Gdiplus::GdiplusStartup(&dwToken, &input, &output);
if(status == Gdiplus::Ok)
{
Gdiplus::Bitmap srcBitmap(L"betty.PNG", FALSE);
Gdiplus::Graphics wndGraphics(staticwindow);
wndGraphics.DrawImage(&srcBitmap, 0, 0);
//Gdiplus::GdiplusShutdown(dwToken);
}
to draw pictures on a static control. I used ResEdit to create my window and I placed a Picture Control on the box. Turns out it seems to be a static control with a specific style to do this.
Now I am creating a dialog box and trying to draw the image again. I used Visual Studio's editor (no choice atm) to create my child window with the picture control called IDC_STATIC.
For some reason the above code no longer works. I step through it with no errors. So what could be wrong? well I looked into the .rc file and it is using some strange class for my picture control and not the static control like resedit's was.
Bwa?
If I use resedit's picture control it works. If I do not, I get no picture.
Any ideas?

Seems I am being silly today.
That code can't be run in WM_INITDIALOG.
What's the first message I *could* run it in?

May be wait for the first WM_PAINT message and do your stuff there?

I had problems in using the WM_INITDIALOG as well, and I solved it using a "bypass". I just used a bool bFirst setting it to TRUE in WM_INITDIALOG. Then in WM_PAINT took a look into, when true do some staff and putting it to false.

As with most drawing, you should be doing it whenever the control receives a
WM_PAINT message

Code is at end of post. I have a picture box control with type Bitmap on my control as position 0,0. I basically want a window where it just displays an image.
However with the current code below, I am unable to get the image to not "be covered up". If I take another window and cover up MY window and then move away, I can then see the image as I desire.
However this is not desired behavior. I have a function commented out called RepaintWindow. It's one of my custom functions. It gets the client rect of the window and calls invalidaterect for that section. A shortcut.
When that is not commented out, I get to see my image (again when moving another window onto MY window) for a brief second then it gets covered by up by gray again.
I am missing a small detail here and by god if I can't see what that is! Thanks for the help.

Do you want to show image on the static control?do you have problem in this section? and also you can use of CImage class for load images.

What in the world could cause me to be unable to draw to a blood PICTURE CONTROL?
|
|
|
|

Since you are drawing in the dialog windows WM_PAINT handler, when the child window (picture control) gets its WM_ERASEBKGND and WM_PAINT message later causes it to erase the image drawn.
you can do,
1. Why don't you set the Bitmap for the picture control at the time of resource editing or dynamically SetBitmap() and allow the picture control to draw in its way.
2. you may subclass the picture control and draw on its paint handler.
3. you actually don't need a picture control if you are drawing the image, remove the picture control and draw the image on the WM_PAINT handler of the dialog as you are doing now, only difference is you don't want to acquire the DC of Picture control but use the dialogs DC and draw where you want in the dialog (where the picture control is supposed to place)
4. Try set the Transparent style to the picture control in the resource editor
|
|
|
|
|
What does the transparent property do?
I can't do it by resource editing. Whenever I draw on a picture control I never see anything. 
I will try SetBitmap tomorrow.
Is there a tutorial on doing the subclassing on the picture control?
|

There's not really a "picture control" - it's just a static control
with the SS_BITMAP style. If you're ok with the way the static control
draws its bitmap then you should just be using the static control that way
instead of doing the drawing yourself.
If you need to draw yourself, then you should be doing so in the control's
WM_PAINT handler. The symptoms seem to indicate you're drawing a bitmap
"underneath" (in the z-order) another control - that means you've got the
wrong HWND 
Also make sure you handle WM_PAINT properly (for any window). If the invalid
region of the window being painted isn't marked valid after painting, then you get
recurring calls to WM_PAINT - bad for performance! Use BeginPaint() and EndPaint()
in your WM_PAINT handlers (and the DC it provides) and the invalid region updating
will be taken care of by the system.
