Checking The File Path Of An Image In A Datagridview?
Apr 10, 2010I have a datagridview with a bunch of columns, one of them being an Image type (DataGridViewImageColumn).What I want to do is basically check to see what the file path of the image in one of those cells is.
I've tried doing like:
If (DataGridView1.Item(7, Number).Value.ToString = "some path" then
'do stuff here
End if
but it always says DataGridView1.Item(7, Number).Value.ToString is just "System.Drawing.Bitmap", instead of the actual file path of the image in the cell.I've also tried the above, without the .ToString, but I get an error saying System.ArgumentException was unhandled (Argument 'Prompt' cannot be converted to type 'String'.)
PictureBox - Image: Select The Path To A Local Folder That Is Within The Application And Get An Image From It?
Sep 15, 2010I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )

View 7 RepliesConvert Image To String?
Apr 3, 2012I want to convert an image to a string, then put it into 1 cell in a datagridview as a string. I've read around on the forums and I saw some people say to use StreamReader, others say BinaryReader. Well Imma try both and see how it comes out. But I'm kinda stump. I'm trying StreamReader first, and I don't know how I should even do this. This is what I've got:
Dim ofd As OpenFileDialog = OpenFileDialog1
ofd.FileName = ""
ofd.Multiselect = False
[Code]....
In my do loop, should I put it into a temp text file and then read that textfile into the datagridview? If I did that, I think it would take up some time.

Apr 28, 2010The coding below is to retrieve the Raw Image Data from the Database and then write as a JPG image file. The problem is the image file (image.jpg) is "nothing" after file created. I guess there is something wrong in the following coding.
fs.Write(rawData, 0, fileSize)
No any runtime errors I can find, and I double check rawData (i.e. Buffer) contains data. But don't know why there is "nothing" inside the image (image.jpg).

Dynamically Swap A String For An Image In Datagridview?
Dec 24, 2011In my windows form I have an empty datagridview that contains strings loaded from a csvfile. The datagridview has no initial column collection. There are four columns in the csv file. In the csv file, columns 1 and 2 have values of true orfalse. So far I am able to load the text perfectly.
What I want to do is change the strings "true" or "false" into an image in my resources (a pretty green checkmark and a red x).
I would like to leave the csv file text as it is, and then change the columns dynamically.
Then, when I save the information back to the csv file, the images must be converted to text strings to accomodate the csv.

View 2 RepliesGetting The Output Image Path To Display?
Jan 8, 2009I designed an interface which calls an executable program written in c. This program needs an input image and outputs another image which has the name: "<the same as the input one>_out". My interface has to display both images (input in picturebox1 and output in picturebox2), I've done so for the input image but now I need to get the path for the output one to display it. I know that there are functions like My.Computer.FileSystem.GetFileInfo() or My.Computer.FileSystem.FindInFiles() but I think they're useless for me, do you think so? Do you know any methods or functions to get the path of my output file? Is it possible?
