I play a game and in the game you acquire skills which you can display on the screen in a box very similar to a data grid. The grid has 3 columns and X number of rows.Column 1 is the name of the skill, column 2 has a descriptive term like "Beginner" and column has the number of points you have acquired in that skill. So it would look something like this:[code]Remember that it is in a data grid so it has cells like an Excel spreed sheet.The program that I use is able to parse the skill name and the points and save that information outside the game to a n area in the program.My question is, is this possible to do something similar in VB? That is something like, Press a hot key, with will get a screen shot, parse the data and save to a data grid in my VB program.
View 2 RepliesI am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?
I am trying to make an Image wrapper class or something. The reason for this is that I need to output a bunch of images only, without pictureboxes. I don't want an imagelist, because I need the images along with their associated image properties which an imagelist cannot provide. I ended up with this :

View 1 RepliesBeen away from coding for almost 10 years, trying to get back into it but am a bit rusty. I have been asked to write a program that will allow users on a network to write hire data, driver data, job calander etc to a SQL database. The program works perfectly at the moment apart from one thing.
The program must allow the users to add an image to a drivers record to have on file, I have read loads of different forums, tutorials etc on how to do this and have managed to get my program to size the image properly and store it as binary data (i think) in the SQL database. I am now having problems doing the reverse and making the program read from the database and display the image in a picture box, the following is my code to save to the database
vb.net
Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
Dim strm As System.IO.Stream

I understand that there may be easier ways to do this, this is simply the way I did this years ago, if any one can give me any pointers or any tips on how to read from the DB and display the image in a picturebox

I have a specific image that I want my application to look for on a specific window. I've done something similar to this along time ago with VB6, but it was slow, and it was checking for specific points in the picture rather than the whole image itself (for speed reasons). I named this image "Image1.jpg" and I want to compare it to the window with the handle "001C08F2" and class "SunAwtCanvas"
View 19 RepliesI'm adding in asp.net (vb) an attribute to an image-button:
imgButton.Attributes.Add("myAttr", "true")
This is working fine. Now I want to read the attribute, but it does not work:

How do I get this thing working?
I have an asp.net repeater. In this repeater I have in each itemtemplate two image buttons.
If I'm clicking on an imagebutton, the other imagebutton in this row changes it's URL. I want that this URL is saved, after clicking on another row's imagebutton. So I'm adding in the repeater event
ItemCommand
Dim imgButton As ImageButton
If e.CommandName = "imgBtn1" Then
imgButton = CType(e.Item.FindControl("imgBtn1"), ImageButton)
imgButton.ImageUrl = "myURL"
[Code] .....
While debugging, it still skips everything, because all Attributes are empty (but actually they are not)!

View 10 RepliesI'm reading a folder to assess the width x height of jpeg's, to classify them in various ways. Opening each as a bitmap and reading the bitmap width and height works but of course is laborious and very slow .... I've read various JPEG file format papers but retrieving the image pixel width and height seems none too obvious. Is there a logical way in VB to get this info quickly? My jpeg's are bog-standard ones made using VB's "Bmap.Save(Fname, ImageFormat.Jpeg)".

I'm storing images in a List Of Image. When I want to clear/remove all the images it contains should I dispose & set each item to nothing before using .Clear? Or can you just call .Clear? I'm doing it like this for now...
' remove all images in list of image named "images".
For i As Integer = 0 to images.Count - 1
images(i).Dispose()
images(i) = Nothing
Next
images.Clear()
Is there a way to read an image pixle by pixle and create a text file based in the information.Lets assume we are reading each pixle from left to right. Once you reach the last pixle of the line you move to the line below that one and continue reading.Here is a very simple "if" statement to help visualize the process:

I currently have a function that loads an XML and takes all of the nodes and makes an object with them and adds them to an array.I need to be able to now see if there are more than one xml doc in a folder, and if so also add their objects to the array until all of them have been read. How would I go about doing this? I've been searching through the System.IO. to see if I could find something but I haven't been able to yet.

I've been using the readprocessmemory function to read some values from another program and it works just fine for small values. However when I'm trying to read something like 5000.123456789 or whatever it doesn't even display the 5000, it just displays something that seems kinda random. Now, I've had this problem before and it helped to just increase the iSize from 1 to 10, but now I can't increase it anymore for some reason. I tried to increase it to 100 but then I got a fatal error. Is there some way to get around this? I guess it could also be because I'm not trying to read an integer but a float, but there is no float in VB, so i tried double, but no go.
