Hi Guys
I heard my teacher talk about that it was possible to acces C++ code and import it into C# using .Net... Is there maybe someone how has done this before and can provide me with som samples. I'm thinking about accesing a C++ -library containing FFT (Fast Fourier) for my signal processing project, which is being programmed in C#... is this possible? seems difficult to find any good FFT implementation in pure C#...
Thanks a lot

I need to stretch a character width horizontally in rich text box - Visual c# - framework 2.0.
Thanks in Advance

Do you mean that you have some random text and that you have to adjust the fontsize to make the text fit the width of a rich textbox?

Yes .... I want to increase the font width alone.
|
|
|
|
|
Uhm. Not sure if that's possible. Setting width alone would end up in unreadable characters.
You would have to set the full font size for it to give any meaning I believe.
You can solve that through a recursive method or other form of loop where you use Graphics MeasureString method with a userdefined font and the width of your textbox. For each iteration, if width of the size returned by MeasureString is still larger then your textboxs width, reduce fontsize by 0.5 for instance.

There is a way to achive the same in Framework 3.0 ....
Some stretch property is available for fonts...
Is there any equivalent method or property available in framework 2.0?

Hello,
If I have a string: xxxxxxImg3.xxx, where x can be anything, and number changes.
How can I specify it using Regex expression?
Thanks.
|
|
|
|
|
Which part of the string do you want to get?
This will filter the Img{digit} part:
Img\d+\.

I want to get the Img# part, and I wanted to group the number part, so later I can get a handle on it. I tried to use: (?<imagenumber>[1-9]*), but that did not work.
Thank you.
|
|
|
|
|
Img(?<number>\d*)\. 
(* allows 0 to infinite digits, + requires at least one digit)

I am trying to get a splash screen to fade out using
Splash.Opacity = .50 But the error list tells me that "An object reference is required for the nonstatic field, method, or property 'System.Windows.Forms.Form.Opacity.get'" At the top of my program i have written
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Text;
using System.Threading;
using System.Windows.Forms;
and my references are: System, System.Data, System.Deployment, System.Drawing, System.Windows.Forms, and System.Xml.
What reference am i missing or how else should i assign the opacity?
Thanks in advance.

Not that kind of reference.
You need a reference to an instance of an object.
Apparently you are calling it from a static method, perhaps from Main.
try something like:
<br />
Form myForm = new MyForm ( ... ) ;<br />
<br />
myForm.Opacity = .50 ;<br />

Ok. I tried what you said, and it says it isn't a problem anymore, but it doesn't fade at all. I first declared "Splash SplashScreen = new Splash();" then under Form1 i put
InitializeComponent();
Form Splash = new Splash () ;
int SpOpac = 0;
Splash.ShowDialog();
while (SpOpac < 100)
{
Thread.Sleep(100);
SpOpac = SpOpac + 1;
Splash.Opacity = SpOpac;
}
Splash.Close();
I must still be doing something wrong. But what?
Thanks for the help.

The UI thread is too busy (stuck in your while loop) to redraw your splash screen. Instead of using a while loop to change the opacity, add a Timer component to your splash form. You can do this in the Visual Studio Forms designer. Set its Interval property to an appropriate time, maybe 100 (milliseconds). Then setup the timer.Tick event handler. EAch time timer.Tick fires, increase the opacity by a little bit until it gets to 1.
p.s. Opacity is a double, not an int. 0 is completely transparent, 1 is fully opaque. So halfway transparent would be 0.5.
p.p.s. optionally, you can try adding a Splash.Update() call right after setting it's opacity. It probably isn't the best way to do it though.

Doesn't Opacity have to decrease? And try putting it in the Load handler rather than the constructor?
|

You may want to consider using AnimateWindow()[^] for a smooth fade in/out effect without having to resort to a loop.

any ideas where i shoud start from or where i can find usefull information..
thanx

Perhaps if you post a screenshot of what you're trying to imitate, we'd be more open to helping you. I've never heard of Microsoft Student, so I don't know what you're trying to accomplish.
