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.

View 9 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 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.

A webserver periodically sends JPG images from a webcam via HTTP post. How do I open and display the images on a VB form from an another computer?
View 2 RepliesI 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:

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'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?
View 3 RepliesI'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)

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.

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...

My program is working and doing everything it is supposed to do outside of two things. My program is supposed to take the items that are under 5 items and show up in a listbox saying they are low stock by clicking file and then display low stock items. The other problem I have is that I am supposed to show everything in the inventory that has a retail price given to it in the other list box that is blank on my mainform. The attempt I have made on the low stock inventory makes the program go into debugging mode.[code]

The application also displays how many prime numbers there are between user's number and zero, and the total sum of all these prime numbers.

Recently I have browsed the web for ways to display a list of files and folders in a list box. I have successfully been able to display files in drive C and get a nurerical value telling how many files were found. However my efforts have been hampered by three distinct problems. I have some experience using batch files and when using them you can state things like "%WINDER%" to go directly to windows folder. I am wondering if there's anything like that used for navigating. And if so could an example be made of it just for clarity?
My second problem is I cant seem to be able to display files and folders. I have been limited to one or the other. That and I cant figure out how to navigate into them to display there contents. The next problem I have is simply having a user interface so you could type a file path or file extention and have the program navigate to it. Is it is possible to click a file path in a list box and chose to delete it. My second last Q how do I display all files and folders including hidden files? And How can I count all files and folders with there contents to dissplay in a listbox.
Create an application for maintaining payroll for a business. When your program begins, read in an input file containing delimited employee records (a sample is provided in the assignment); each record contains the employee name, the current salary and the number of years employed. Display only the names of the employees in sorted order, and when the user selects a particular employee, display the salary and number of years employed for that employee, allowing the user to edit the record. Provide methods of adding and removing employee records as well, and update the input file with all changes before the program close
I want to put the salary and years into separate text boxes. Heres my code so far, I realize its certainly not the most efficient way, but its functional.

I have a listbox that is connected to a text file and this file is created when the program opens for the first time and then users can add data to the file as they wish. However what I am having a problem with is that how can I link the selected item in the listview to a textbox.
I.e.
Listview has 3 columns: Name, Surname and Location
Then when the line is selected i want the 3 individual variables to display in 3 seperate text boxes that has been set up.

View 3 RepliesIve been trying to add images in SUBitems in a listbox. After some plundering i figured out they've somewhy removed that property in vb.net 2010. Ive tried several results ive found on google, url... but that didnt seem to work in vb.net2010 (or am i just not good at copypasting?). Anyway i need a brither mind than mine to work out some other solution. Im not required to use listbox, but hopefully something similar. Ive taken a look at DataGridView, but i really dont want to process that little information i got, into a database.
