VS 2010 - Filling DataGrid Columns With Excel Data
Mar 26, 2012I finally got this code to work:
vb
Dim path As String = OpenFileDialog1.FileName
Dim myDataset As New DataSet()
Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""")
Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.Fill(myDataset)
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
So replace:
vb
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text

VB 2008 - Dynamically Filling The Listview With Groups And Items
Mar 26, 2009I am currently using VB 2008 and there is a form I'm using which contains a listview control. I am dynamically filling the listview with groups and items. After I fill it up, it is supposed to look like this:
[CODE]...
Each item is specific for each group. The problem I have is that when I maximize the form to full size, and everything expands, the items change positions into something like this:

How can I make the listview keep the items in the "row" view always, instead of the "column" view whether I maximize or not?
VS 2008 - Webbrowser - Click A Button After Filling Out A Form
Mar 21, 2010I am trying to click a button after filling out a form in vb.net 2008. I have the following code but I cannot seem to get it to work.
WebBrowser1.Document.All("username").InnerText = TextBox1.Text
WebBrowser1.Document.All("password").InnerText = TextBox2.Text
WebBrowser1.Document.GetElementById("submit_button").InvokeMember("submit")
I am trying to fill in a simple login form and click submit. I am able to copy the information into the username and password fields but cannot seem to get it to click submit within the code.
Here is the html code for the submit button below:
<div id="submit_button">
<button type="submit" value="Login Now!" onmouseover="this.style.backgroundPosition='bottom';" onmouseout="this.style.backgroundPosition='top';" onclick="return SetFocus();">Login Now!</button>
</div>
Why this isn't working I cannot seem to figure it out.

VS 2008 Mouse Pointer Disappears When Filling Textbox?
Jan 31, 2011I have a main form "Parent" and another "child" form. When I am filling a textbox in the child form the mouse pointer disappears. Then I hit the tab key to jump to a combobox. At this time when I move the mouse, the pointer doesn't come up until I click the mouse button. This is annoying and the user of my program doesn't like it. How can I keep the mouse pointer always on top. NOte: although the main form has the parent property as true, the other child form are not defined as child forms.

VS 2008 Filling Array With Pixel Data And Turning It Into A Bitmap?
Jul 22, 2009I have a small 10px by 10px image, and I want to use VB.NET to find out if that image is (an exact) part of a larger image.I thought a method of doing this would be to lock the bits of the larger image into memory and then loop through each pixel in the image and for each pixel, I could take the 10px by 10px section which is down and to the right of that pixel.. and then compare it to my smaller image.
This is the code I have so far:
'Lockbits of larger image to memory
Dim bmp As New Bitmap(Image.FromFile(System.AppDomain.CurrentDomain.BaseDirectory() & "picture.bmp"))
Dim pxF As PixelFormat = PixelFormat.Format24bppRgb
[code]....
when I'm looping through the 10 by 10 section and I find the R G B bytes for each pixel, how do I store this in my rawImage array so I can convert it to a back bitmap and compare it with my original small 10by10 image?

Mar 18, 2010I'm fairly inexperienced with VB but have been trying to get "save" functionality out of a program I'm trying to write. Basically I have a Datagridview and I want to write each line from the grid into a .txt file. So what I've been trying to do is use Datagridview.Items and then variables as column / row indexes to move cell by cell left to right , writing each cells data to an array which also increments along the way. Then using WriteLine to write the array to the text file, zero'ing all the counters then starting all over again for the next row.... make sense?
