Is it possible to set IF case using the images present in the datagridviewimagecolumn?
Example:
If current row image = "Red.png"... show error msg
If current row image = "Green.png"... Insert to database
i am new to VB.NET and am creating an application for twitter, my problem is that i have a datagrid on my form. On my code i have created a dataTable to store the user messages in one column and the usernames in the other column. My problem is that i cannot add a third column to the dataTable to store the user images, how do i do this? my sample code is as below :

I have a question about a Select Case, and how to go about writting it.In my pages, I call to a SQL Database, that returns values from a column. The columns present two types of data, numeric and varchar
e.g 2N or .10 (they present nickles) I would like my onscreen to display images, instead of that value (once they have been found). Where 2N = imageNickle + imageNickle, as well as .10 = imageNickle + imageNickle (or display 2 of the images in place, rather) I would like to just focus on the (varchar) at this point. Is their an easier way to write a select statement than say:

Environment: Visual Basic 2005, Windows XPI have the below data grid, I am using. I am trying to show tooltips, when I hover over the "Status" column. Red => MissingGreen => AvailableThe "Status" column is of type: DataGridViewImageColumn. The Images are inserted from "My.resources" I have tried to accomplish it using the below code, but it is not working and believe there might be a better way.

I have a gridview where ALL cells have a value that is an image from the filesystem, but I need to access these files for a certain function and so I've been trying to create a method that disposes of all these images thereby freeing them up on the filesystem (was received permission denied errors). The following loop worked for the first row of images but I can't work out how to do it for all rows:
or Each c As DataGridViewImageColumn In dGV.Columns
c.Image.Dispose()
Next

I would like to make my 'Image File Path' column in my datatable set to a 'DataGridViewImageColumn'. I would then like each of the rows in this column to display a image. The image value would be populated from the 'image file path' contained in that cell of the datatable. At the moment i cannot get this to work no matter how many times i try it. At best it just shows the same image in every row and in the wrong column. As the table is populated 'dynamically' when a search is performed this is proving very hard. Below is an image showing the table and what results i am currently getting:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
dt.Clear()

I have a DataGridViewImageColumn with an image in it I would like to make the only area to perform a function of mine when I click it. I can click the row and get it to work but can't seem to only make just the imagecloumn the clickable region.
So as an example I have
Private Sub dgrdStatus_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgrdStatus.CellClick
MessageBox.Show("You chose " & dgrdStatus.Rows(e.RowIndex).Cells("columnCustomerName").Value)
Works for the whole row, my issue is I only want to be able to click the imagecolumn to do this. Guessing I am missing the right item similar to dgrdStatus_CellClick but can't quite pinpoint the fix.

I want my TextBox to make the text i enter as Sentence Case(ProperCase).. but i dont want to write any code in an event like Lost Focus or KeyPress
Just by default when ever a user enter or types in a textbox the first letter of every word should automatically converted into UpperCase
When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?

If the result is 86 and it's mod by 43 the answer is 2 Case 2 is not firing. it just goes to the end of the procedure.
It looks like impossible but...
Try
Select Case command
Case 1
smth()
Case 2
[code]....
Firstly Case 2 runs. Throws exception. And right after this debugger shows that next processed statement is Case Else. Only after Case Else throws own exception Catch block start working. I've never seen this trick. Why can this happened?I'm sure the block is entered once (not like this:first enter hit Case 2 and second hit Case Else).
Update:-To Matt Wilko. Thank you for answering. I've switch to Strict On in Options of VS2010 but nothing has changed. Command is variable, not function. Watch tool shows that on each step Command is the same ( Command = 2).
Fixed. Yeeaaaahhh. I simplefy code to

and change project to Console app. This works as I mention. The fix was in Release mode. I was debugging in Release mode. When I switch to Debug mode everything goes as it should.
I need to add Functions for the Case 10 and Case 13 in this code. The code in each select case needs to be moved to the two functions which then returns the code once its called from the Sub Main section. But I am having a really hard time figuring out what exactly gets moved to each function.[code]I'm not sure what exactly to put into the individual Functions and how to change up the Sub Main section.
View 4 RepliesThe idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 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...

I 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?
