C# really isn't suited for this. Packet mangling is a low-level operation and requires optimal performance. A managed environment really isn't suited for this.
There are many tunneling programs - including secure ones like ssh - which already do the job and do it well. ssh, for example, is written by experienced cryptographers and developers and is supported by the community and several companies.

I'm trying to disply a picturebox on top of an existing picturebox and the second one is showing up underneath the first and isn't visible. Is their a simple solution to remedy this , I really hope so because I don't want to rewrite a bunch of code. The picturebox that is underneath has a bitmap of a poker table and the picturebox on top is a bitmap of the cards that are going to lay on the table. If anyone can help I would really appreciate it. Thanks.

See if these two methods help you:
BringToFront()
SendToBack()

I tried these but it doesn't work. I tried to SendToBack the image that was supposed to be on the bottom and SendToFront on the image that was supposed to be on top but the SendToFront image was still underneath. Thanks any way though.

Well you have to make a class and inherit pictureBox.
then inside the class
protected override CreateParams CreateParams
{
get
{
CreateParams cp=base.CreateParams;
cp.ExStyle|=0x00000020;
return cp;
}
Protected override void OnPaintBackground(PaintEventArgs e)
{
}

This is a pretty bad way of trying to comp an image. While not either extend PictureBox or even just some other control and override OnPaint. Paint the pictures in the order you want them to appear. So, you'd paint the bottom image first, then paint the top image second. Overriding OnPaint will pass you a PaintEventArgs, from which you can use the Graphics property to call DrawImage or DrawImageUnscaled. It's really quite easy.

When the mouse is moved over PrintPreviewControl, how to change the cursor when it is on the document that is displayed in the control. It should remain at default state outside the document.

if i change it, the cursor will change as soon as mouse enters in the PrintPreviewControl, thats not solving my problem, i want it to change only on the document that is displayed inside the control. meaning, there exist some vacant area inside the control that is not been occupied by the displayed document, in that area cursor should have default value. It should change on the area occupied by the document.
regards

THe PrintPreview Control doesn't expose this kind of functionality. You'd have to extend the control and add this functionality yourself. Calculating the screen coordinates of the page 'image' is going to be the hard part. Since the underlying control does all the painting, your going to have a ruff time doing this. You could at least use the OnEnter and OnLeave events of the control to know when the mouse is actually in the control. From there, you'd have to figure out the coordinates relative to the page image rectangle(s).
No, I haven't done it before, and don't know exactly how. I have no source code or sample to give you...

More over can we decide the layout of the document to be displayed, meaning can we decide like A4 or Letter size layout for the document?
|
|

|

Yes. See the PageSettings property, which sets the default page size, though you can change it if desired while printing each page. It's all documented in the .NET Framework SDK.

I think I did't get your answer, there is no such property in the property list of PrintPreviewControl.
Please elaborate more, also guide me about the first question

The PageSettings doesn't belong to PrintPreview... It belongs to the PrintDocument that the PrintPreview control is using as a source.
A simple search in the documentation would have told you this. All you had to do is type 'PageSettings' into the Index...

How to sence click even on the document when two pages are displayed in PrintPreviewControl.
How to identify which page is clicked?
|
|
|
|

The PrintPreviewControl doesn't expose this functionality. You'd have to extend the PrintPreviewControl class and write the functionality in yourself. Getting the screen coordinates of the page 'images' will be the ruff part (Good Luck!). Once you have that, it's not too hard to figure out if the mouse cursor is inside those rectangles to determine which page is clicked.
A better bet would be to look into a 3rd party PrintPreviewControl.

Hi All
I have a problem where i am reading in a csv file but within the file each field within a line has double quotes surrounding the data, and occassionally the data will have commas in it eg: "01","test","this,is the,problem","test"
What i want to do is remove the commas within the quotes, and leave everything else.
If any one has an idear please help.
regards Odyssey

Actually, the real problem is how you're parsing the file. Instead of simply using String.Split to split using commas, enumerate the characters in the line and keep track of when you come across a double quote. Increment a counter or set a boolean. When you run into another quote, decrement your counter or reset a boolean. When the counter is 0 or your boolean is false, then you can parse a comma-dilimited field. The typical CSV (there really isn't a standard) uses double quotes to signify that a delimited field may contain the actual delimiters. Simply removing the delimiters within those quotes would be corrupting the data.

You can either use regular expression or odbc connection using microsoft text driver to parse csv files.

<br />
string s = "\"01\",\"test\",\"this,is the,problem\",\"test\"";<br />
string[] values = Regex.Split(s, @"(?<=\x22)\s*,\s*(?=\x22)");<br />
foreach (string val in values)<br />
Console.WriteLine(val);
OUTPUT:
"01"
"test"
"this,is the,problem"
"test"
Note that this solution requires every field to be delimited with double-quotes. If some fields are not (as often the case with CSV numeric data) the Split above will not work. However, such data is still certainly within the capabilities of a RE parse … instead of the RE Split, you would capture the desired data in the Groups collection using Match … the RE would describe the values you want; and not the space between them (as in the split above).
Also note that I used zero-width look-ahead and look behind assertions to keep the double quotes on the values. If you did not want them as part of the value, the Split RE would look as follows: @"\x22\s*,\s*\x22". You would then have to remove a double quote at the beginning of the first value and one at the end of the last.

Hi
I tryed to use the RTF codes in RtfBox, doesnt work 
How can i bold a text in a RTFBox without the "SELECT Method"(Select the text, and the Selection Font and Color ) ?
only \b doesnt work, appers a square
Thanks.
|
|
|
|
|
First off, you're getting the square because you're trying to set RTF codes using the Text property, which has no knowledge of RTF codes. (And you're not using the @ symbol in front of your string, so C# thinks "\b" is an escape character. Either make it a string literal or escape the backslash "\\b".)
If you want direct access to the RTF codes in a RichTextBox, you should use the Rtf or SelectedRtf properties.
However, I don't think that's what you're looking for, as it will make it quite a bit more difficult than using SelectionFont, SelectionColor, etc. The Rtf and SelectedRtf properties will give you the entire Rtf formatting string for the contents of the control or selection, respectively. There are intended more for pasting RTF from other sources. You can't use them to simply turn bold or color on or off.
