i'm really a beginner here, so hopefully somebody can help me. i'm currently doing a dialog application. i need to add a "box" to show a vector( a graphic image of binary '1' or '0' that looks like square wave) inside it. The vector can taken from a file( that consist just '1' or '0') and i need to draw the vector(square wave where '1' is showing high and '0' is showing low amplitude). For starter, may i know how to create the "box"? Which function do you recommend me to use? Later the i also need to be able to zoom in/out to view the vector in the "box".
Thanks.

Can you be more specific about box?

Your description is not really clear... It looks like you need to draw a chart with a square wave into it. Am I right ?
If yes, you can take a look at my article here[^], maybe you can use it for your purpose ? It also support zooming.
If this is not the case, then you'll probably need to create your own custom control that contains the functionalities your are looking for.

actually i need to do a dialog based application for a IC tester(hardware). In this application, it will send some vector(series of '1' and '0' ) to the IC tester(harware) and then after the testing it will return back a result vector(series of '1' and '0' ) to the computer. Therefore, in the dialog, it will hv a button to start the testing. Once the button is pressed, the testing will begin and later in the dialog, it should display the input vector and also the output vector( which looks like a square wave to represent 1 or 0). The data for the vector can be taken from a file saved in text format.
The problem now is that how do i display the vector in my dialog box? Should i create and list box or picture to display the graph in the dialog? Also, are there anybody who knows how to draw a square wave by getting the data from a file( the file contains a series of 1 and 0, and if 1, the wave amplitude is high and if 0 it will show low).
Thanks in advance.

I can't make any more controlls... no more buttons, listboxes.. no even static text..
If I take something away, "delete one of the objects", Then I can 1 more on... But then it's maxed out again and won't make any more. My program is a big dialog with about 400 objects on it... Is there something mabey that has a max setting.
I need to put on about 12 more objects into my dialog... Anyone got any ideas?

The resource editor does have a limit and you hit it. To add more controls you can always add them dynamically at run time using the Create functions.
|
|
|
|
|
Ok.. thanks.. to bad I can't just up the limit... Oh well..
I think I'll just go through all my static text objects and code them in.. That should free up bunches...
Thanks for the info...

|
|
Can you explain why you use of 400 objects,please?
|
|
|
|

IIRC a dialog resource has a limit of 255 controls. If you need more, you can create them in your WM_INITDIALOG handler.

I'am trying to use VC to operate Ms Excel, but I can't set the back color of cells, what can I do for it?

Here's a code segment written in VB
With Selection.Interior
.ColorIndex = 3 ' this is red ...
.Pattern = xlSolid
End With
I think it it easy to know how to do it in VC from that.
By the way, there is a way to know how to get some work accomplished in your codes: just open Excel, and record a macro doing just the same thing, then you can check the code in Excel's Macro editor. I got that piece of code in this way.

Good idear! I have solved my problem! Thank u!
And do it in VC just need to add some codes follow:
Interior bkColor;
bkColor.AttachDispatch(range.GetInterior().pdispVal)
bkColor.SetColor(COleVariant((long)0x000000)); //black
Also Give Thank to a friend named ◎Alpha◎ who helped me, God will bless him and his family!

Im using the SetTimer() function to try and achieve a 100Hz query via RS-232... My problem that I have run into, is that we i check the time that the timer is occuring at, using std::GetLocalTime(), and comparing it to the last time it was called, it appears that it running at 20Hz, or every 50 milliseconds as oppose to 10 ms. Any ideas on why this is happening, and how to fix it?

For that kind of resolution you'll probably want to use a multimedia timer.
Timer events coming through windows messages are pretty innacurate and resolution is not so good
(as you've seen).
Check out timeGetDevCaps(), timeBeginPeriod(), timeSetEvent(), etc.

Hello
I am trying to use wide character constants in my program in a switch statement basically as follows:
TCHAR chChar = L'ä';
switch( chChar )
{
case L'ä': break;
case L'ö': break;
}
UNICODE and _UNICODE are both defined.
The compiler gives me warning C4066: "characters beyond first in wide-character constant ignored". This leads to error C2196: "case value '195' already used".
Is there any way around this?
Thanks.

If you cast L'ä' and L'ö' to short , what do you get? If the values are different, then use casting for the workaround. If not, it would seem that there's an issue with the compiler.

I can't reproduce that (warning level 3).
Are you sure _UNICODE is defined before #include <tchar.h> ??

Don't use any characters outside of the ASCII range in your source code. Use the \x escape with the Unicode code points for the characters - L'\xe4' for ä, L'\xf6' for ö, and so on.

Well, in the software i'm developing, we need to display images on a folder. I'm using the FindFirstFile function and specifying a directory. This is working fine.
The problem arises when there's a filename that contains extended characters, such as "U+FB98: Arabic Letter Gueh Initial Form", which is this one: ﮘ. Now, the FindFirstFile function returns it, but the FindFileData.cFileName returns a filename with some question marks(I suppose these are wildcards) instead of the symbols.
This would not be a problem if the loading CBitmap would work... but it doesnt. I suppose it's in fact because of these symbols being replaced with question marks.
Is there any way around this? How can I effectively get the filename I need? Is this a problem with gdiplus CBitmap loading operation or with the filename being given with question marks?
Thanks in advance!

Are you using the Unicode version of FindFirstFile..?

Well, I tried to. I have to prefix this "\\?\" to the path right? In C the prefix would be written as "\\\\?\\". This produces the exact same results.
<br />
strPattern = "\\\\?\\" + m_folder;<br />
<br />
if (strPattern.Right(1) != TEXT("\\") )<br />
strPattern += "\\";<br />
strPattern += "*.*";<br />
hFind = ::FindFirstFile(strPattern, &FindFileData);
Any ideas?

No. You do not have to add the prefix. Just go to your project settings and change your project to using UNICODE.
And you have to change all string constants in your program to wide char strings, i.e., "*.*" should be replaced with L"*.*" , unless you are using the TEXT macro like:
