Have Gone through the Timer Tutotorial . That was excelent . Great.
Lot of Thanks to Nemanja Trifunovic . And Cheers to CODE PROJECT !!!
I have gone through the Documnet ,and decided to go for Queue Timers.
Since Win 2000 is ok for me .
What do u think about reply from toxcct?
if the windows Latency of 55 Ms (as toxcct Says) then
is it possible that widows will attend to any of the timer messages?
Lets see .. i will try Out. And let u all Know.

you cannot be 1ms precise just because Windows scheduler is already up to about 55ms. and windows is not a real-time OS, so, timer interrupts don't have priority uppon the kernel.

You can use the ClearCommError function (even though the name does not suggest it.)

Yes, the name of the function was not really what I was expecting.
Thank you

I have a CEdit control on a dialog box and I'm creating a dynamic rectangle on the CEdit but it doesn't scroll vertically when I put the rectangle on the bottom of the CEdit?!! I've set the multiline+ vertical scroll parameters
Please help me! my code has come below:
CRect rc, statusRect;
GetDlgItem(IDC_GRAPH_EDIT)->GetWindowRect(rc);
CWnd* pWnd = GetDlgItem(IDC_GRAPH_EDIT);
ScreenToClient(rc);
statusRect.top = rc.bottom - 40;
statusRect.bottom = statusRect.top + 20;
statusRect.left = rc.Width()/2 - 40;
statusRect.right = statusRect.left + 80;
m_dynamic = new CButton;
m_dynamic->Create("Dynamic",WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON|BS_OWNERDRAW|BS_MULTILINE,statusRect,pWnd,2000);
m_dynamic->SetFont(fontGeorgia);
m_dynamic->SetColor(BLUE, LBLUE);
m_dynamic->ShowWindow(SW_SHOW);
I've tried the following codes but it didn't help:
((CEdit *)(GetDlgItem(IDC_GRAPH_EDIT)))->SetSel(GetWindowTextLength(),-1);
or
((CEdit *)(GetDlgItem(IDC_GRAPH_EDIT)))->PostMessage(WM_VSCROLL, SB_BOTTOM);
UpdateData(TRUE);
or
((CEdit *)(GetDlgItem(IDC_GRAPH_EDIT)))->LineScroll(2);
Any idea or suggestion will be appreciated.
thanks

CEdit represents a simple text editor, even if you subclassed the control I dought you could do it. The edit-control client area does not actualy scroll, that's an illusion. When you scroll the text it just changes the position of the upper left courner character, where drawing is to start. The edit-control would have to think that your custom-control is part of the text.
If you need to insert an object into an edit type control then you should be using CRichEditCtrl, and even then it may need to be an OLE control.

Well.....actually I'm going to draw a graph (some colored rectangles that are connected by some colored arrows) on a dialog. Since the display sould be always like a single vertical line of boxes with a scrolling feature, I though CEdit might be a good choice.
Now.. I'm waiting for your suggestion for such an implementation 
Thanks a lot

If you have not already visited controls section of CP, then give it a shot. There are two graph controls at CP that I know of (one is it ATL/COM section). The other two choice would be to: look into how to use a view (CScrollView) in a dialog box or write your own code to handle the scrolling.

I encountered a problem today. I have a dialog containing a rich edit control which I use to highlight certain parts of a text. The control is set to readonly in the dialog editor. I also use SetOptions() to set it as readonly in OnInitDialog. This works pretty much ok.
When I select a text snippet, I am able to drag the text and drop it into any other window accepting text. But when I do, the selected text is deleted from the read-only rich edit control.
Any ideas?

Hi,
I want to display a simple dialog that displays "Please Wait..." while a task is performed then goes away by itself when the task is complete.
What's the simplest way to do this?
Thanks,
Ali

|
|
|
|
when the task ends, just send a WM_CLOSE to the window displaying the "please wait..."

In VC++ 6, there's an add-in to insert a progress dialog box. (not sure about vc++7) Once inserted, you could strip out the progress controls/code, and use the default static control for your "Please wait..." message.

Hi
You can use CStatic Class to show "please wait..." message.
if u wanted to know when task ended u can use Threads API functions or MFC threads functions as AfxBeginThread(threadfun,hwnd,threadpriority) ,
then create thread and Use WaitForSingleObject(....) API function to determine when your task ended
.
if u need more help contact me on faroq_tam2004@yahoo.com.
If this dos'nt help u im sorry.
Bye.

hi CPians, toxcct again.
another wish i had for my prog was to have the possibility to switch all the text between French & English.
I so used the default string table (french) to insert the french strings, and created an US english for the translated strings. all the strings refering to the same thing in both tables had the same IDs (#define names).
Questions :
1. Am i right to set the same IDs (#define names) in the string in both tables, or do they only need to have the same value (int) ?
2. how can i switch from one language to the other and vice versa ?
3. Is there a better/simplest way to do this far away from what i am doing now ?

Can't say whether it's the best way of doing it, but I use resource-only dlls.

You should also search for "satellite dlls" at MSDN, I think there's an example project.

In our app we have support for 3 languages (quite a drag and a lot of overhead)
We give the same names in the string tables for all three languages. (make 1, copy it and change the text)
When we change the language setting of windows our app switches too.
Good luck.

ok but, how to change the language while the application is running ?
i have a combobox with 2 entries ("Français" & "English"), and i would like (when a selection change is detected) to alter all the strings from one table to the other associated with the selected language.

In that case I would think ahead.
Load your captions dynamically with an xml document. This way you can add languages very easy in the future.
You should then still find a solution on what to do when your app changes etc. So maybe not a good track either.
I'm not sure it's so easy to what you want, maybe you can trigger the table-change, but I wouldn't know how  , sorry.
good luck.

Hi .
u can create 2 Dll files with your resources and
then use API function to load your resources as u wanted.
On different Dll files u can use the same ID for the string.
that is mean only change the dll file for specific language.
for Example create Eng.dll file for English Version and
Frn.dll for France Version.
this make your program more esaer to development.

What I did to solve this problem was put all the strings in a *.ini file (you could also use a *.xml file as suggested by V). By using this method, other people can add as many translations as they want, without you having to recompile your app or any extraneous dlls.
