How to change font in CRichEditCtrl, please help me
thanks
|
|
|
|

I've never used CRichEditCtrl, but have you tried SetFont (inherited from CWnd)?

Hi All !
One problem pursues me for a few years already:
all my Win32 apps, written in VC++ (5.0-6.0),
crash on the second run under debugger.
Toolbar code in comctl32.dll causes access violation.
In more details:
1)The crap arises only when the app
is run 2 times successively from the VC++ IDE.
When running my app standalone, all's ok.
2)The program crashes when a mouse is moved
over the toolbar. WM_MOUSEMOVE is finally
dispatched to DefWindowProc() in comctl32.dll,
and there fails.
The mouse coordinates seem to be correct.
3)If toolbar is hidden, it's allright.
4)This bug seems to be not accidental
concatenation of circumstances:
this happened on different Windows versions,
under both VC5 and VC6, after many reinstallations
of the VC++ and OS etc,
and, finally, with all my Win32 GUI apps -
independently of tyhe architecture of the app,
and of the way I use tollbars
(containing ReBar, different styles, etc.)
5) The bug arises and disappears from time to time,
during the course of program development.
It seems that it depends somehow
on the size of the .exe or something like that.
Anyone ever faced this problem ?
Any help or hint would be appreciated !
Thanks in advance !

Solution is not into diferent systems or VC++. Try to find bug into your project. I had never this or similar problem and it is imposible to tell you something else.

I'm trying to create a dialog window, that becomes opaque when a mouse hovers over it and when
the mouse leaves the window, it should become transparent again.
My problem here is that when a mouse is over a control in the dialog window, it doesn't work the
way I want - the dialog does not recognize that the mouse is hovering over it.
What should I do?
And my second question is: Do you have any how to do the same UI as in Real Player One. I mean:
when a mouse is moved over the display window three zoom buttons appear. I actually would like
to do it a little bit more different: when I move the mouse over the upper-left corner of the
client area of a window the buttons should appear.
I'm doing Win32 programming in my spare time for a few months now and I'm nothing but a beginner
yet. Sorry if my questions are too stupid.
Regards,
Z.

check out the SetCapture() and ReleaseCapture() stuff
the second point i would solve by putting a static control on the dialog box and make it invisible but use it to capture the mouse and do your button / control thing there
"... and so i said to him ... if it don't dance (or code) and you can't eat it either f**k it or throw it away"

You should check for the mouse hover in the controls also. Derive a class fromm your controls and override the mouse events you need to.

Define a rectangle with in your view in the upper-left corner of the client area and use that rectangle to test if the mouse is over it and act accordingly. Off the top of my head I can't remember the mouse event, on mouse move? Use the point you get to see if that point is in your rectangle and if so, draw your controls.

Hi,
I simply want to be able to draw a verticle line (1 pixel wide) of a desired length (ex. 134 pixels tall) from the bottom of my screen up. Specifing color would also be nice
Thanks,

You want to do this with DirectDraw? Sorry, but that still isn't simple!
|
|
|
|

Get the DC from the surface (GetDC) and the use plain GDI functions as usual.

|

Sorry, but I'm new to this. How do you "use the plain GDI functions as usual"? Is there a DrawLine() Function?
Thanks,

I'm still learning MFC and started a test project that I am using to learn how to enable/disable menu items and toolbar buttons. I did not know whether or not to name the toolbar buttons on the CDialogBar toolbar with the same IDs as the menu items.
After changing some of the toolbar buttons to the same IDs, I got everything to work except one button which the resource editor would not allow me to change because it said I had a duplicate ID. The only difference with this one is that it is for a menu called "IDR_STOPMENU" that gets inserted once the user selects an action and gets removed after the "ID_STOPMENU" menuitem is selected from within this menu.
So, figuring that maybe the order of the buttons on the toolbar were not the same as the menuitems, I started to play around with the order and finally was able to change one other button but then I decided to manually change the command ID used in the OnStopMenu() and ON_UPDATE_COMMAND_UI() functions as well as in the resource editor because I thought ID_MENUSTOP looked stupid when used as an ID on both the menu and button. This screwed everything up so I put everything back and now if I put a breakpoint in either of these two functions they are not called at all. How do I get back? Did I do something that screwed up classwizard or what?

To further show off my ignorance about STL, how does STL handle errors?
I'd try to error check a vector.reserve call (by other means than calling and comparing against capacity afterwards).
I'd expected it to make use of it's own exception class, but my debugger says I'm mistaken. (Yes, I live with the VC++ 6 STL implem)

Show as some code please!

class Foo {
std::vector<Bar> vec1;
std::vector<TCHAR> vec2;
void Reserve(int sz1, int sz2) {
vec1.reserve(sz1);
vec2.reserve(sz2);
if (everythingIsOK ) {
...
}
}
}
When one of the reserve calls fail, it's "silent" (i.e. it keeps the old size). I could compare sz1==capacity(), but that doesn't look like STL to me - I thought STL would consistently use exceptions situations like this.

This is due to a documented bug with Microsofts implementation of ::operator new.
You have to provide your own implementation of the global operator new function (or provide an allocator to the vector that does the right thing) that throws an exception of type std::bad_alloc when the memory request can't be met.

I want to populate an edit control with a paragraph. The only way to populate a multiline edit I found is to have
\r\n at the end of each line, so obviously it doesnt look like a paragraph. Do I have to use a CRichEdit, or will my poor CEdit do the task?
Thanks,
ns

You get automatic text wrapping in en edit control when the ES_AUTOHSCROLL style is not set. this way, you can save your precious \r\n's for the paragraph breaks.
Other than that, you would need to use the RickEdit.

What's up coders... I am interested in changing the size of the shelltraywnd so that I can have a window similar to the task bar but my own which sits at the top of the screen. Then when any other window is maximized it will think that the bottom of my new task bar or window is the top of the screen and won't go past it.
So in reality I wanna change the height that all windows maximize to on the screen. Right now the go to the top of the screen but I would like to be able to change this so that they only maximize to 200 pixels below the screen and then I can fit an application in there so it sorta simulates what the task bar is doing if it were at the top of the screen.
If anyone could help me or give me some hints as to what this would involve that would be awesome.
Peace

i , all guys here.
I confront a handicap in my VC study , and expect your help.
Now , I am writting a class inheriting CWnd . and I want my class have the function to respond the UI message such as mousedown or keydown etc.
Have some master-hands can solve this problem . If you have some sample classes that can show to me ,please email to me :polosheng@yeah.net. thanks.
Another , I have made a sample class . it can pass the complier,but when linked ,the exe file didn't respond the lbuttondown message.And here is the code. Conld you give me some suggestions?
