Snippet from the link:
For all of you who are looking to do a similar feat to what I did, the command is as follows:
rasdial <vpn_name> <vpn_username> <vpn_password>
To disconnect:
rasdial <vpn_name> /d
Thus, in usable terms, my line would look like this:
System.Diagnostics.Process.Start("rasdial.exe", "My_VPN My_Username My_Password");
To disconnect from the VPN, simply use this line:
System.Diagnostics.Process.Start("rasdial.exe", "My_VPN /d");

Can anyone tell me how shall I create a new control a button inside a textbox. The button will have a search(loop) picture I will use it as a lookup control in my application.
|
|
|
|
|
why put a button inside a text box? Surely a control designed to distinguish importance like a group box would serve a better purpose then trying to couple a text box that contains a button?
|
|
|
|
|
Hi,
use Button.Controls.Add() ;-

You have it backwards, he wants a button within a text box, not the other way around.

Take a look at the source code for v 1.1 in this[^] article. The FileChooserLibrary contains a control which enables the sort of functionality you are looking for. It is unfinished, but working, and should give you some ideas at the very least.

Hi
I would like to update the GUI once specific scenario occurs
I’ve application that have GUI and logic layers
At logic layers I have hierarchy classes witch means that class ‘A’ use class ‘B’ that use class ‘C’, etc
At Class ‘C’ I would like to notify GUI (such as update counter edit box) once a condition exist (for example
if ((m_num % 100) == 0))
UpdateGUI(m_num)
I know I can use the event mechanism
Create and register event at class A,B,C and register also the event at the GUI
Is there any other way to call event from very low class to very higher class hierarchy?
I hope I describe my question properly
Thanks

The only other way that springs to mind is to use P/Invoke to utilize the SendMessage/PostMessage API calls. That is a lot of work though, when the Event mechanism is there.

Dear All,
I have developed an application which does some manipulation with database and it also uploads and downloads files from web.
the application is basically in Winform Layout, it has Notify Icon which shows the status of uploading and downloading.
the problem is in logging of computer, if the application is running, the computer does not log off which i want it to log off. Y it doesent log off?
if i close the application and point to log off, computer can log off successfully.

Hi,
with which method do you close the form manualy? did the closing handler stop closing? 
kind regards
|
|
|
|
|
thx, sorry for late reply,
yes i have certain conditions in closing event, based on those condition i am closing my form.
a simple condition is a boolean value, if that bool value is true than i am closing my form.
i think this causes the form not to close when i log off my compuer
how can i solve this, Please?

Hi,
you're lucky, because I've got announcement for your post. 
Okay, I have a way:
You may use
Microsoft.Win32.SystemEvents.SessionEnding += new Microsoft.Win32.SessionEndingEventHandler(SystemEvents_SessionEnding);
and then
void SystemEvents_SessionEnding(object sender, Microsoft.Win32.SessionEndingEventArgs e)
{
switch (e.Reason)
{
case Microsoft.Win32.SessionEndReasons.Logoff:
break;
case Microsoft.Win32.SessionEndReasons.SystemShutdown:
break;
default:
break;
}
}
you may omit the switch block, because you don't need it. Everytime the handler is called, Windows logs you off, or shuts down.
IMPORTANT: On Form_Closing (or Form_Closed) you MUST remove handler from SessionEnding-Event:
Microsoft.Win32.SystemEvents.SessionEnding -= new Microsoft.Win32.SessionEndingEventHandler(SystemEvents_SessionEnding)
hope it helps
kind regards

i have tried following but still it didnt helped me
void SystemEvents_SessionEnding(object sender, Microsoft.Win32.SessionEndingEventArgs e)
{
exitProgram=true;
Envoirnemt.Exit();
}

Don't know if Envoirnemt.Exit(); works. Try this.Close(); instead, if it is a windows form application

I have done following
void MainFormLoad(object sender, EventArgs e)
{
SystemEvents.SessionEnding +=new SessionEndingEventHandler(SystemEvents_SessionEnding);
}
void SystemEvents_SessionEnding(object sender,Microsoft.Win32.SessionEndingEventArgs e)
{
StreamWriter sw=new StreamWriter(@"c:\log.txt",true);
sw.WriteLine(e.Reason.ToString());
sw.WriteLine("close");
sw.Close();
exitProgram=true;
Close();
}
looks like nothing happens when i log off or shut down the computer
i see nothing in my c drive and also my winform never closes.
Note: i have also notify icon in my WinForm. It always appears. Y it doesent closes?

Hi guys,
i have a litte problem with Microsofts PixelFormat. I have a Byte[] containing my R-G-B-Pixel values. The problem is, that PixelFormat.Format24bppRgb takes the pixel-values essentially in order B-G-R ... whats a little bit crappy. How could i get my array into a 24bpp-bitmap, with correct color-information? I need a very fast solution, because there are more than one images per second, with a size of more than 6000x2000 pixel, which must be issued.
Any possibility? Tried it with unsafe code and switching pixel per pixel-value, but it takes nearly 3 secs on an image with that size. Are there any tricks to get a correct colored image faster?
Regards
Andre

Are you absolutely sure about that?
I don't do a lot with graphics, but I have never had any problems with PixelFormat.Format24bppRgb. Is there any chance that your byte[] has become, for want of a better word, corrupted. Maybe it contains Alpha values, therefore slowly moving out of sync.
It is difficult to offer more as you do not explain exactly what it is that you are trying to do. For example where are you getting the byte[] from?

Im getting the byte[] from an Camera, and yes, its 100% in order R-G-B. For testing, i made a byte[] by hand in a test-project.
public byte[] makeImg()
{
int x = 0;
byte[] Img = new Byte[f_WIDTH * f_HEIGHT*3];
for (int i = 0; i < f_WIDTH * f_HEIGHT*3; i+=3, x++)
{
if (x == f_WIDTH)
{
x = 0;
}
if (x <= f_WIDTH/3)
{
Img[i] = Convert.ToByte(255);
Img[i + 1] = Convert.ToByte(0);
Img[i + 2] = Convert.ToByte(0);
}
if (x > f_WIDTH / 3 && x < (f_WIDTH / 3)*2)
{
Img[i] = Convert.ToByte(0);
Img[i + 1] = Convert.ToByte(255);
Img[i + 2] = Convert.ToByte(0);
}
if (x > (f_WIDTH / 3) * 2)
{
Img[i] = Convert.ToByte(0);
Img[i + 1] = Convert.ToByte(0);
Img[i + 2] = Convert.ToByte(255);
}
}
return Img;
}
When i print it on screen, or put it into a bmp-file, the colors in the resulting image are blue-green-red ... in that order.

Here is my code:
public partial class ByteArrayToImageForm : Form
{
private int f_WIDTH = 100;
private int f_HEIGHT = 100;
private byte[] testImageArray;
public ByteArrayToImageForm()
{
InitializeComponent();
this.testImageArray = this.MakeImage();
}
public byte[] MakeImage()
{
int x = 0;
byte[] Img = new Byte[f_WIDTH * f_HEIGHT * 3];
for (int i = 0; i < f_WIDTH * f_HEIGHT * 3; i += 3, x++)
{
if (x == f_WIDTH)
{
x = 0;
}
if (x <= f_WIDTH / 3)
{
Img[i] = 255;
Img[i + 1] = 0;
Img[i + 2] = 0;
}
if (x > f_WIDTH / 3 && x < (f_WIDTH / 3) * 2)
{
Img[i] = 0;
Img[i + 1] = 255;
Img[i + 2] = 0;
}
if (x > (f_WIDTH / 3) * 2)
{
Img[i] = 0;
Img[i + 1] = 0;
Img[i + 2] = 255;
}
}
return Img;
}
private void ByteArrayToImageForm_Paint(object sender, PaintEventArgs e)
{
int arrayIndex = 0;
int x = 0;
int y = 0;
Bitmap visibleBitmap = new Bitmap(this.f_WIDTH, this.f_HEIGHT, PixelFormat.Format24bppRgb);
while (arrayIndex < this.testImageArray.Length)
{
visibleBitmap.SetPixel(x, y,
Color.FromArgb(this.testImageArray[arrayIndex],
this.testImageArray[arrayIndex + 1],
this.testImageArray[arrayIndex + 2]));
x++;
if (x >= this.f_WIDTH)
{
x = 0;
y++;
}
arrayIndex += 3;
}
int drawX = (this.ClientRectangle.Width - visibleBitmap.Width) / 2;
int drawY = (this.ClientRectangle.Height - visibleBitmap.Height) / 2;
e.Graphics.DrawImage(visibleBitmap, drawX, drawY);
}
}
Try it out. **NOTE** I have dispensed with the Convert.ToByte parts from your code as they are not necessary, although it does not alter the output (I tried both ways).
So unless you were using Convert.ToByte because you were converting from int, for example, which might explain your problems, I am at a loss.
Sorry!

Hi everyone,
I try to create Cubes with Analysis Services in Visual Studio (C#) 2005, but my problem is...
... I created the datasource, datasourcesight, the cube and dimensions, but if I try to compile it and add it to SQL Servermanagement Studio it means, that it can't be added to the server cause the name might me wrong...
Sorry I am from germany and so I only have the german errorlog:
Fehler 1 Das Projekt konnte aufgrund der folgenden Konnektivitätsprobleme nicht auf dem Server 'test' bereitgestellt werden: Es kann keine Verbindung hergestellt werden. Stellen Sie sicher, dass der Server ausgeführt wird.. Überprüfen oder aktualisieren Sie den Namen des Zielservers, indem Sie mit der rechten Maustaste im Projektmappen-Explorer auf das Projekt klicken. Wählen Sie 'Projekteigenschaften' aus, klicken Sie auf die Registerkarte 'Bereitstellung', und geben Sie dann den Namen des Servers ein.
... my knowledge: it just means that the connection with the server failed, because I typed the wrong servername into the project 
greets,
Mschauder

Hi,
you've got the wrong forum. The front-end is Visual Studio, yes, but it's mainly used plug-in for that is: SQL Server Business Intelligence Development Studio. And so it's not C#.
Try to ask the question on database forum.
BTW: Is the name of your server really 'test' and not maybe 'localhost', check the project properties Deployment -> Target -> Server
