I wasnt hoping for magic I was hoping there was a line of code which you could add it to page rather then just one control at a time.

Sure - I don't think so.

Hi all,
I have a windows service application that needs to make request to a remote web service (https:// ...) for uploading files. the contact mechanism between them is a SSL based channel.
I assigned my windows service to run under a specified user account and installed the client certificate with that user account as well.
And I am getting this exception as title, however, strange enough, I do not get this exception all the time, i got this exception sporadically. Does it prove that I did configure certificate properly? if so, what other reasons would cause this exception???
Any suggestion would be appriciated!!

I now have a problem with a piece of code which worked before!
My code to get an image object from a directory is:
System.Drawing.Image fullSizeImg = System.Drawing.Image.FromFile(imgFullPath);
Then I resize it as follows:
System.Drawing.Image thumbNailImg = fullSizeImg.GetThumbnailImage(newWidth, newHeight, new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback), IntPtr.Zero);
In the debugger, fullSizeImg and thumbNailImg are {System.Drawing.Bitmap} so they must be ok. However, when I use the following code to save the image:
thumbNailImg.Save(fullPath);
I get the error message:
CS0103: The name 'thumbNailImg' does not exist in the current context
However, if I try and save the fullSizeImg (before resizing) this works fine, so I'm totally confused and desperate for help!

Forgive me if i'm incorrect in saying this but don't you need to create a NEW instance of the thumbNailImg first?

I'm a newbie to all this (so please bear with me  ) - I found the vb version of this code on the web and attempted to rewrite as C#. I thought I was creating a new instance in this line:
System.Drawing.Image thumbNailImg = fullSizeImg.GetThumbnailImage(newWidth, newHeight, new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback), IntPtr.Zero);
If not, please tell me how.
Many thanks

Yes and I'm sure it was working yesterday although I have extended my code a bit
|
|
|
|

I am using populating a ListBox with the files I want to resize and when the user clicks a button, the method goProcessImages is called and I traverse through each one resizing it (well I'm trying to!).

Because of you are creating the variable inside try block, it is showing the error.
should be like this
System.Drawing.Image thumbNailImg;
try
{
thumbNailImg = fullSizeImg.GetThumbnailImage(newWidth, newHeight, new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback), IntPtr.Zero);
}

Thanks - tried that but get message:
CS0165: Use of unassigned local variable 'thumbNailImg'
on line:
thumbNailImg.Save(fullPath);
Thanks

I dont think so,
Because GetThumbnailImage returns an Image object and thumbNailImg is also an Image object.
Am I right?

Show your full code.
Member 3402886 wrote: fullSizeImg.GetThumbnailImage
Resizing image using GetThumbnailImage is inefficient and it returns only the thumbnail image attached to each image. So you will get pretty poorly resized image.
Create a Bitmap with the new size and width, load your image into a Graphics instance, use DrawImage() to draw image into the required size. Save the bitmap. You will get image resized without loosing quality.

Convert.ToInt32(DecimalValue)
or
lblValue.Text = decimalValue.ToString("#,#0");
or
txtValueBox.Text = decimalValue.ToString("#,#0");
