am working with Web Browser control and with emails ".eml" ,simply am just navigating the WeBBrowser to the email object in my computer and is displaying my email body
but if the email has attachment picture(NOT AN EMBEDDED PICTURE) then the Browser automatically display that image to the center of the browser for example the last line of the html code is <CENTER><IMG SRC="CID:{A4BE96B0-6195-4D93- 45E-97D4B1CA3539}/nature2.jpg"></CENTER> but actually the email dose not has this picture as embedded but is only an attachment ,and the browser is displaying it.
is there any way which i can easily disable that functionality or i should modified the code and replace that string with nothing. ?

View 3 RepliesI was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
View 2 RepliesI am making futile attempts to get the DataGridView control in a Windows Form to disply several rows of images. The images are all contained on the local disk. The names of the image files (all .JPG or .GIF files) are taken from an XML file. The XML is not the issue, since some of of the images actually appear.
The control has three DataGridViewImageColumn objects. Each column is set up to display a file called Blank.gif which is a transparent GIF containing a single pixel. Later, during the form's Load event, I replace each cell's Value property with the image that the XML file says should be in the column. The XML file contains the name of the file, and I use the System.Drawing.Image.FromFile() method to create the image object from the file name.
The behavior I am experiencing is that that only the very last row of images is properly displayed. The rows above it display the Blank.gif file as if they had never been assigned their intended images. If I change the code so that it will only iterate through three images (one row), all the images show up in the grid. If I then change the code so that six images are processed, only the second row of images is diplayed, and the first row shows only the Blank.gif file's image content. If I change the code to process nine images, the first six show up as blank, and the last three in the final row are properly displayed.
I have lost a considerable amount of my little remaining hair trying to fix this problem to no avail.
The code is as follows:
Imports System.Text
Imports System.Windows.Forms
Imports System.Xml

I'm currently attempting a project where I need to display a series of images from a database, in thumbnail form, then fullscreen when they are selected. Next/Back arrows will be used to navigate through different pages of images. These images will be across a number of categories each one with a different table in the database. It is very important that the user can change the images in the database.
Rather than have a number of different pages and each image designated to a picturebox, I was wondering how I could make it so the program just displays the next 6-8 images from the database in the same picture boxes, giving a message when the it reaches EOF, This way the number and order of the pictures can be changed just by changing the database.
I have a listbox displaying information about different workstations detected on a local network. Each line in the listbox is a different device. I would like, if possible, to display images on the end of each line (A green dot for one rule, a red dot for another, etc).
I have the images of the 'dots' as very small gif files.
i manage to display the table but my imgcol that contain image only display a box of x.. in my database column for the image, i put this.

I'm having a problem with displaying JPEG images in a RichTextBox. When I insert a JPEG image into a RTB it automatically gets converted to a wmetafile8 and displays correctly - however, if i insert a JPEG image into file via another method (currently using the web) it get saved as a jpegblip (as you would expect) but the RTB will not display it. Opening the rtf document in Word displays the image correctly.I have tried this with png and gif files also but none of the images will display unless they are wmetafiles. Is this a limitation with the RichTextBox or is there another reason?

I'm sure it's something simple, but I'm wracking my brain with this one.

I am using Visual Basic 2008 for a Windows Form application. I have a PictureBox on the form that I need to display a series of 12 JPG files, one every four seconds. For the life of me, I cannot seem to figure out how to get the Timer control and its Click event to work.
In pseudo code, I need something as simple as the following:
1. show JPG #1 in picture box
2. 4 second delay
3. show JPG #2 in picture box
4. 4 second delay
etc.
I have a Timer on the Form set with Interval = 4000. I have a PictureBox. I have all the images in the Project. I am embarrassed to say that I have spent 4-5 hours searching the Web for sample code or something helpful, but am still stuck.
All the elements are there. It's just a matter of understanding how to pause the image displayed in the picturebox for 4 seconds before moving onto the next image in the series.
I need to display images when I press a key on the keyboard. I have a form with a textbox and a label on it. When I type a letter in the textbox it appears on the label. I got that part to work. But now I want to display a image in the label when I press a key on the keyboard. I have found some images on the internet that I want to display when I press a key on the keyboard. For example when I type the letter A in the textbox instead of A appearing I want an image of an apple to appear, or if I type the letter B a banana would appear, or if I type the letter D a dog would appear. I have been searching on how to this I came across the keyboard event such as the keypress event. Can I use a keypress event of the textbox to do this. Can I assign a certain image to a certain key on the keyboard, and have that image display whenever I press that key.

View 2 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

View 5 RepliesI am starting to develop a card game client for a CCG a friend of mine and I are creating.
I have 2 forms Client.vb and Hand.vb linked with a module.vb
In essence when the app starts up I see the client. I can then click the "Hand" button and the Hand Window is shown as well.
What my goal is is to have it so that when i hover over the card (picturebox) in my hand form that it displays a larger image of that card in the preview box (Another picture box) In Client.vb
I have everything working except when i actually mouse over the image in the hand form it creates an error:
Error:A first chance exception of type 'System.NullReferenceException' occurred in CCG 2.0.exe
The code in the mouse hover event:
Code:
F1.PictureBox2.Image = F2.PictureBox1.Image

I'm working on a site that I've inherited that's built with ASP.Net, which I'm only slightly familiar with. One of the pages allows for a link to a document (word or pdf) that, when clicked on, prompts the user to save or open the file, but does not reveal the true path of the file. This way it prevents users from pasting a url to a file - the link is to an aspx file that checks for a valid session, and then retrieves the file.
Anyway, because there's a lot of legacy code, I need to do this with a bunch of static htm files as well, however these files need to be displayed rather than prompting the user to save them, which is what happens now. I tried changing the content type to application/text, application/html, text/html, etc. and that didn't work, then tried adding a response header of content-disposition inline. When I do that, build, and try linking to the file, I get a couple of runtime exceptions:
[FormatException: Input string was not in a correct format.]
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDecimal(String Value, NumberFormatInfo NumberFormat) +206
Microsoft.VisualBasic.CompilerServices.Conversions.ToLong(String Value) +110
