Add image to ImageList and set File Name as Tag property

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :Windows Application

I'd like to create a thumbnail viewer to view all .jpg files within a folder.

So i create thumbnails and add them to a ImageList.

          Image img1 = Image.FromFile(fi.FullName);
          img1.Tag = fi.Name;
          imageList.Images.Add(getThumbnaiImage(imageList.ImageSize.Width, img1));

then add them to my ListView.

      for (int j = 0; j < imageList.Images.Count; j++)
        this.listView1.Items.Add("Image\n" + j);
        this.listView1.Items[j].ImageIndex = j;

Instead of the 'description' "Image\n" + j, i'd like to use the Tag property which should contain the file name.
doesn't work.

Error: System.NullReferenceException was unhandled.

How can i show the thumbnails in the ListView with the real file names ?

Image file does not want to overwrite.


 I am having an issue with saving an image file to a temp file on the server after it is cropped.  I upload the image on one page and then modify it on another with the option to rotate or crop.  I have the crop feature set as a fixed size and am using JavaScript to accomplish this.  I am getting an error when I try to save the file as the original file name to overwrite it with the modified image file.  I know this has got to be something simple that I am overlooking, but I have been looking at it for a while and can't seem to spot the problem.  I currently have the image saved as "studentid_temp.jpg" in the temp folder.  I want to overwrite this file with the new cropped version of the photo.  Below is the code that i'm using, which gives me the error: A generic error occurred in GDI+.

When I change the file ending to something different (like studentid_temp1.jpg) the new cropped image saves without a problem because it does not have to overwrite the original. 

I have set the permissions on the folder to allow read/write functionality.

Any ideas to easily accomplish this overwrite?  I thought overwrite was kind of the default when a file came across with the same name, or is it because I still have the image open from the display (how would I fix that, if that's

Insert image into Infopath form and save to SharePoint as PDF file


I have an InfoPath web-enabled form in MOSS 2007, that is integrated with a K2 blackpoint process for an approval workflow.

Once the form (a Purchase Order request form) has been approved in the K2 workflow process, I switch the form view to a "print-friendly" view for the requestor to view from the browser.  However, now I need to go one step further with this scenario:

1) I need to somehow insert/embed an image with the scanned-in signature of the approver (likely stored in a SP doc library) at the signature line section of my form.  Also, what are the security requirements for storing such images, but not granting all users access to these (e.g. only services accounts that need to access this for embedding into the form, etc.)?

2) Then I need to convert this final "print-friendly" view of the form (with the signature image) to a PDF document so that I can store it in SharePoint (and email it to the requestor using K2's email event capabilities).

Can anyone help me with a solution to both of these requirement, or point me to some resources for this (even 3rd party components are open-game).

How to delete an image file assigned to a PictureBox xontrol ?

In a Windows form application, some image files are assigned to PictureBox controls. I am trying to delete those image files. The first approach [1] with "Image.FromFile" gives an error message of "Another process is using this image file", although "Image.Dispose()" is executed. The second approach [2] using "Image.FromStream" results (X) images for PictureBoxes and Buttons, if "fs.Close()" is inclided. Without "fs.Close()", it gives the same error message of "Another process is using...". How can I display images properly and delete those images files ? Thanks [1] pictureBoxSelected.Image = Image.FromFile(@actualImage); . . . pictureBoxSelected.Image.Dispose(); pictureBoxSelected.Image = Image.FromFile(@tempImage);                                                if (System.IO.File.Exists(actualImage) == true) {     System.IO.File.Delete(actualImage); } [2] FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read); pictureBox.Image = System.Drawing.Image.FromStream(fs); fs.Close();

ImageList and a system image list handle

How can I have an ImageList use an image list handle of a systems image list, such as one that can be returned from SHGetFileInfo ? My image list is associated with a ListView control and this could be easily done in Win32 through the LVM_SETIMAGELIST message with an image list handle but I see no easy way of doing this with the .Net System.Windows.Forms.ImageList component.

property setting in report server (2008) config file is not working as expected.



I have set the <WorkingSetMinimum> property to 2.4GB in my reportserver 2008 config file.

By defintion, <WorkingSetMinimum> setting means,

  1. Lower limit of service memory consumption; memory will not be released if the consumption is below this amount, though the service will not reserve the designated amount of memory when it starts.
  2. If service uses more than the designated amout of memory, it will release back the memory only till this declared value and not beyond that, which means it should keep 2.4GB as designated.

See this link for definition: http://books.google.com/books?id=mzY_Xo_9J-gC&pg=PA589&lpg=PA589&dq=What+is+%3Cworkingsetminimum%3E+in+report+server+configuration+file&source=bl&ots=r_xhRp8erj&sig=E_o0-Dh2SXOgMNrW3sptt5oZrYI&hl=en&ei=f5mjTNeNM5O8ccmErJMI&sa=X&oi=book_result&ct=result&resnum=4&ved=0CCAQ6AEwAw#
