RichTextBox And Displaying Jpeg Images
Sep 4, 2009
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 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 need to send up to to selected images (such as an apple) to pictureboxe's on a results page. at the moment I'm using global variables to attempt to display the images like this:
Me.pbItem1.Image = New Bitmap("images\" & gstItem1 & ".jpg")
Me.pbItem2.Image = New Bitmap("images\" & gstItem2 & ".jpg")
I get a directorynotfoundexception 'Could not find a part of the path '\images\apple.jpg' error. I'm new to VB and think this must have something to do with the default path or something.

I would like to parse through and display and picture and description for each 'item' in an XML file. I can't figure out the image part, and I've only been able to concatenate the 'description' to display it:
[Code]...
I'm at the right elements in the tree; I can display the first picture, and I've been able to access all of the 'description' elements. But I need to have each 'item' element display together.

I've written some code to get an image file from a OpenFileDialog, and then offset the X position of the image by -50, and then display that offset image in a panel. But for some reason, it is displaying the image twice inside that panel. Could someone please tell me how to get it to only display the offset image in the panel? I'm sure it's something simple, but I'm wracking my brain with this one.
If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
Dim Bitmap As New Bitmap(OpenFileDialog1.FileName)
Dim Graphic As Graphics = Graphics.FromImage(Bitmap)

I'm trying to make a way for them to export orders to a .rtf file. In order to preserve formatting (bold, underline, etc.), I'm creating a RichTextBox (through code) and formatting the text appropriately. To save the output, I'm simply using the RichTextBox.SaveFile method. Now, to list all of the products that were sold in the order, I'm deriving the information from a ListView. The ListView contains the product name, product price, and quantity sold of that product. I cannot find a way to list the output in a table-like structure, so I tried making a DataGridView and pasting it onto the RichTextBox. Unfortunately, this didn't work at all, so I was wondering if anyone had any ideas as to what I can do. I can't simply use Tabs to space out the information because it doesn't get formatted nicely.

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.

The new issue is that the knife item gets added to the listbox, but when I click on it...the picture isn't displayed in the picture box, and the description isn't displayed in the rich text box. I have the image path and name correct. I have no idea why the description isn't going in the text box.
Code:
Public Class FormInventory
Private Sub FormInventory_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am using VB2008 Express. In my program I have a loop that is updating variables. As these variables are updated, the updated information must be displayed in the RichTextBox. Everything works fine and I can display my first line of data, but then the next time the second line of data overwrites the first line. I would like each update to be on a new line, so I need to force a new line in my code. Here is the code for part of the loop so far.[code]

I 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
Im Almost certain im going about this the wrong way but I cant seem to figure out any other way...
PS.I have attached an image to demonstrate what Im trying to do...

I'm experimenting with the RichTextBox control. My goal is to replace certain user input with an image object. For example, when the user used ":-)" in the RichTextBox it will be replaced with a simple image (like ).
I use the TextChanged event on the RichTextBox to replace any found textual smiley with an image. The code below works, but only works on the first found ":-)". When the user used ":-)" twice the first image is being removed from the RichTextBox. No matter howmuch times ":-)" is found, there will only be one image in the RichTextBox (for the last found ":-)").
Private Sub RichTextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RichTextBox1.TextChanged
Dim LastIndex As Integer
[Code]....
I also don't know if the whole clipboard thing (clearing it, storing the image, restoring the original data) is the best way to do it, but I will look at that later.

I am loading a KJV.rtf file at program startup into RichTextBoxDisplay. When I want to select, lets say, Matthew Chapter 1, I want the program to take me to Matthew Chapter 1. I know I could just load a seperate file into the rtbDisplay, but do you know how many chapters and books are in the Bible..
