I am using VS2008. I have a table in which the jpg images are stored. I can retrieve the images from the table and display it in datagridview. But many images are of different sizes. So the cell height of the datagridview changes according to the image size. Is it possible to give a fixed cell size for the image column and also shrink the image to that cell height.

View 4 RepliesFor c = 0 To grd.Columns.Count - 1
grd.Columns(c).Resizable = DataGridViewTriState.True
Next c
That allows all the columns in my DataGridView to be resizable EXCEPT the last column. Why?I DO get the little resizable-mouse-pointer... but you can only make the column SMALLER, never WIDER.(Same problem if I try to set all the columns to Resizable, using the VB.net IDE)Shouldn't I be able to resize ANY column I want, bigger or smaller?
I want to pre-load a number of images from the web, so that I can display them in a form, and scroll through them without delay. It can be a large number, but i only need to pre-load perhaps 20, and then remove/add in advance, as I scroll through. The images will typically be .GIF or .PNG, of quite small size, <50kb. The link for any single image will look something like this: [URL]..and I will keep a list of all the links I need to access.
What "type" shall I use to store these images? And how do I make web requests to put the data into this type? I guess it will be more convenient to keep this as in-code list of some memorystream type (?) instead of saving them to disk and having to deal with file names and stuff..? Also, what type of control shall I use to display such images? Do I use a PictureBox?And if a memorystream is indeed the best choice, how do I make this show in the picturebox?
If I have an array of urls which link to images, how can I list them as thumbnails in my application?

I am developing a visual basic 2008 express edtion program of an organisation that should get images from the system and display on image/picture box. further the program should save the displayed image in access database so that it can be retrieved together when you want to search the information about that particular employee.
View 7 RepliesI have an application i am working on which gets data and places it into a dataview.
One of the columns contains a url that shows an image of the item being listed, my question is is it possible to have a floating imagebox so that the image is displayed when i mouseover the url? this would be a bit like a preview the images are not large (64x100 say)
My initial thoughts on this would be to use a tooltip but can i use images from a url with a tooltip? if so how, if not how can it be done?
When you put an image in a picturebox, and have the sizing format for the picturebox set to zoom, how would you get the width and height of the image?
View 3 RepliesPretending I have a class that inherits off Control, how would I handle the parent form's Resize and Move events within the control? I have a painting glitch that happens when the form is resized or moved. Right now in the form I just have:
vb.net Private Sub frmMain_ResizeMove(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles Me.Resize, Me.Move Me.Refresh()End Sub
But this can't be the proper way to do it, considering Refresh() invalidates all children (will be slow and flashing if the form has lots of controls). I want to basically do the above code inside the control.
Edit:This is the glitch after a resize of the parent form:
And this is what the button is supposed to look like:

View 14 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 have a datagridview bound to an Access datatable. It is nothing more than a one column list of chemicals. To allow the user to more easily navigate the list, if they press a letter it will jump to the first chemical alphabetically of that letter. If they keep tapping that same letter it will move down that list one by one. This all works fine. The problem is if you hold down the letter it will progress down the list but it doesn't show that progression. I want it to function much like if you hold down the down arrow key in a datable you'll see each successive cell be selected as it goes down the column.

View 6 RepliesMy program parses chat room text. In the room there are smileys that get displayed. What I'm trying to do is parse out the image URL, download the image and put the smiley in the correct spot between the text of the message.I can do the parsing and downloading of the image into the datagridview but this only works of the column is set as an image column. Obviously due to the nature of the program I need to be able to put both text and images into the same cell. How can I do this?
View 4 RepliesI'm just wondering if it's possible to display a string in a integer column in a DataGridView? The reason I'm asking is that I have a column wich displays the place for each runner (it's a sports application). And if the runner is disqualified, it will display "DSQ" instead of the place.
Now, if I want to sort by clicking the column header, there's a problem if there are more than 10 runners. If there are like 12 runners, the sorting will be like this:

if there is a more efficient way than a select case method for each image and each picture box.
When I view images on my development PC they look fine, but when I view them on other PC's, the images are sized differently and often get cut off.
