Checking The File Path Of An Image In A Datagridview?
Apr 10, 2010
I 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'.)

With all the smarts of actually loading images being done by the .net framework, seems like I shouldn't have to repeat it all in my code by checking for magic numbers, or using a hack like this:[code]Am I missing something obvious, like System.Drawing.IsImage(stream)?

I had 7 picture box which is for creating my digital clock.At first, i put my 7 image at the desktop and store my image as array to call out when the program is running.So my image path is
Public myImg(7) As Bitmap
myImg(0) = New Bitmap("C:UsersDesktop�.png")
Then after i install the program at others desktop.The program cant be run.I think is cause by the file path.Which file path should i put for the image to enable program can run at any desktop.

I currently have 4 images that I need to load into a picture box at different times, it works fine for me but if I send it to a friend it wont work because the file path is different. I use this at the moment:
If filmType = "Jumper" Then
img = "E:TheatreBookinginimages"
picFilms.Load(img)
lblFilmInfo.Text = ("A genetic anomaly allows a young man to teleport himself anywhere.")
lblFilmInfoTwo.Text = ("This gift leads him into a war that has existed for centuries.")
End If

I have a database that contains a file path in 4 of the columns. I am using VB Express 2008 on Windows 7 (I have already figured out the 32bit to 64bit problem while working with access databases). This path is generated from code on another form. I have a datagridview that contains the path in a columns. i want to be able to click on the file path column and the file (in this case it is either a .jpg or .pdf) opens.

I have a dynamic path and every time I want to check it and if it is the root of drive warn user, so I am doing this:
Code:
If MyPath = Directory.GetDirectoryRoot(MyPath) Then
'Warn user
End if
MyPath is returned from a control like FolderBrowseDialog so I'm sure it cannot be an invalid path...

I have a Access program and I'm using VBA code in the background to run Winunzip using shell command. Well, the path of the .zip file has spaces in it and it's not recongizing the path as a valid path. Is there a another way to tackle this problem besides the shell?I can't us pkzip either. Has you can see I had to use progra~1 instead of Program Files.[code]

I 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" )

Completely new to ASP.net
Page Language="vb"
Microsoft .NET Framework Version:2.0.50727.3603; ASP.NET Version:2.0.50727.3082
I want to check on the server for the existence of an image, then if it does exist, display the image wrapped in other code. E.g.
if "/images/name.jpg" exists then
<div><img src="/images/name.jpg"></div>
else
Do nothing.
Seems really simple to me but NOTHING I have tried has worked (compilation errors). I've tried examples using system.io, DIM stuff with 'FileInfo', Set fs. FileInfo examples produce 'not defined' errors, 'Set' says it's outdated and not used anymore and so on.

I am trying to read and display a file using MapPath as follows :
Response.ContentType = "Application/pdf"
Dim FilePath As String = MapPath("../Document/123.pdf")
Response.WriteFile(FilePath)
Response.End()
This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.

I'm using acrobat that returns unix paths instead of windows path's. So im wondering if there is a way in vb.net to convert the path to windows path.
i tried using:
docs(i) = javaScriptObj.path().ToString.Replace("/", "").Substring(1)
position = docs(i).IndexOf("")
docs(i) = docs(i).Substring(0, position) + ":" + docs(i).Substring(position + 1)
this only works on local files, but fails when im starting to use network drives.

1. I can check a DataSet for errors with DataSet.HasErrors and I wonder how to check the same thing for a DataGridView.
2. Coming from MS Access I am not used to batch editing a dataset via a datagridview for instance. Think of a multi user Windows forms application / SQL Server setup. So I wonder if it's ok to just save the data after a row has changed, edited or deleted and not wait till all modification are done and then do a batch update?

I want to check if two combobox values are equal. The comboboxes are in a datagridview.I found you need to use datagridview_EditingControlShowing to add a handler to the comobo boxes for selectedindexchanged. I can do this with this code.
Code:
Private Sub dgridRegisters_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgridRegisters.EditingControlShowing
Dim combo As ComboBox = CType(e.Control, ComboBox)
[code]....
However, the message box comes up for every combobox in my datagrid when I change the index, not just the cmbPort2. I would like to have something like this...
If cmbPort1.selectedindex == cmbport2.selectedindex then
'do something
endif
..but it doesn't seem possible.

I have an unbound Datagridview which gets its data from an array from an Excel sheet. I give the user the chance to amend this data in a Datagridview. I then need to know if the user has changed this data before processing it further. I have in vain, tried to use IsCurrentRowDirty, IsCurrentCellDirty, looping through DGV matrix etc. It seems that because the DGV is not bound to a dataset then the normal properties like HasChanged and the 2 above don't seem to work. Here is my attempted code which is not working:
Dim DGRow As DataGridViewRow
Dim DGCell As DataGridViewCell
For Each DGRow In DGV_ReviewDetails.Rows
