2 ways:
1. Place the string in a MemoryStream, then Load the stream, the RichTextBox should detect it is RTF.
2. Place the string in the clipboard, set its format to RTF, then paste that object to the RichTextBox.
I wouldnt normally suggest a way like #2, but as the 1st method will overwrite all the current content (and that may not be desirable), I do mention it.

If I understood you correctly, you can set the Rtf property of a RichTextBox to this string and then you can get lines count through Lines.Length.

I am having problems with saving listview items into a text file..
Here is my code:
<br />
<br />
StringBuilder sb = new StringBuilder();<br />
<br />
for each (ListViewItem lvi in lstbox.Items)<br />
{<br />
sb.Append(lvi.Text);<br />
sb.Append(Environment.NewLine);<br />
}<br />
<br />
System.IO.StreamWriter sw = new System.IO.StreamWriter(saveSearch.FileName);<br />
for (int i = 0; i < lstbox.Items.Count -1 ; i++)<br />
sw.WriteLine(sb.ToString());<br />
sw.Close();<br />
<br />
But this is only showing the first column header..
I have five colums headers..
How to save all???

That shouldn't even compile, "for each" should be one word "foreach".
Why are you doing "Items.Count - 1" in the for loop?
Why are you closing it after the first pass, if you have a good reason for that, why even use a for loop?

More to the point, why is there even a for loop there. he's already got a for each loop to go through all the list view items and build up the string. he should just be writing out the string at this point. no second loop needed from what I can tell.

I mention the loop of next line of my post, but so many head scratchers in there as to why its been done. You never know... people do weird things sometimes and think its justified. Chalk this one up to inexperience/lack of general understanding of coding on his part.

oh yeah, I must have read it too quickly.

for each (ListViewItem lvi in lstbox.Items)
{
sb.Append(lvi.Text);
loop through the lvi.SubItems collection here, and add the text of each sub item to your string builder.
sb.Append(Environment.NewLine);
}

you have to get all other columns from lstbox by using lstbox.SubItems[index]then write them into file
|
|
|
|
|
The code I written there was converted from C++/CLI to C#..
So bear with me..
I can write all those for loops, that is not a problem..
Just give me an idea how to get all column data in the string builder..

Hello,
You definitely have to show more information (code) that someone can help you!
All the best,

The problem might be below mentioned point:
* If image file is corrupted.
* Bitmap.FromFile method on a file stream that is not finished writing to a file.
* The image file does not have a valid image format or GDI+ does not support the pixel format of the file.
* The program does not have permissions to access the image file.
* The BackgroundImage propery is set directly from the Bitmap.FromFile method.

1)file is'nt corrupted
2)No IO operations on File
3)Program has permissions on file

The image file does not have a valid image format or GDI+ does not support the pixel format of the file.
can u please explain me more about it?

Can catch the Error in Try Catch Block so can find the exact error message.
Please verify once again your image file might be file is not correct format.
explaon me also what you have done before loading the file

thanks for replying
it loads while viewing from external program.I am downloading this file from Ftpserver,saving it on my System's drive and then accessing it.
I have given enough time for file to download. Unless the whole file is downloaded i dont proceed for Loading the image.

Can post here code ?
I think you have defined buffere size little bit maximum.

Dont dispose of the image (img1). This is a known issue.
|
|
|
|
|
Disposing or not disposing of the image object (img1) doesnt help.
While using
Bitmap img1 = new Bitmap(path, false);
its throwing Invalid Parameter Used Exception.
|
|
|
|
|
Image img =image.FromFile(path);
img.GetThumbnailImage(150, 150, new Image.GetThumbnailImageAbort(Nothing), IntPtr.Zero);
Nothing will be a function which will return a bool like .
private bool Nothing()
{
return true;
}
|
|
|
|
|
m am working with C#.net 1.1 desktop application.
As soon as Image img1 = Image.FromFile(iSelected); executes it throws an memoryexception
