IDE Stop Filling In The Rest Of A Property When Creating A New Property?
Nov 5, 2011when I'm creating a new property in Visual Basic .NET in Visual Studio 2010, the rest of the Property (template?) doesn't complete the basic framework of the property in the code editor. It is now treating a statement like:
Public Property Length() As Integer
Instead of completing the property as it used to (code follows), it simply goes to the next line:
Public Property Length() As Integer
Get[code].....
What happens now is that, if I type in the 'End Property' code, the name of the property will now be highlighted as an error since it doesn't have a 'Get' or 'Set' portion.However, when I THEN type the 'Get' on the line following the 'Public Property Length() As Integer', then the balance of the property is created in the code automatically.I don't know how this got changed, but would love to change it back.Does anyone know if there's a setting in VS2010 that addresses this, or if it's something with the basic templates that visual studio uses for creating the basic code components?The weird thing is that for everything else, from class declarations, structures, functions and subs, the IDE still creates the balance of the code structure correctly. The only area where it doesn't is for Property declarations.

View 1 RepliesFilling Multiple TXT Files With XML Data?
Jun 22, 2010What I am trying to do is create a conosle app in vb.net 2008. I have a XML file (data_file.xml), and a template file (template.txt). The template file contains a few sentences, each one containing a placeholder which needs to be filled. I need to create multiple output files (.txt), which contains the contents of the template file, with the placeholders filled with the values of the placeholders in the XMl file.
The XML file is at the moment:
<?xml version="1.0" ?>

- <group>
<placeholder1>Nigel</placeholder1>
[Code] .....
As it stands, I can create one template file, containing the filled template contents using only the first group of placeholders. I am nearly there, just trying to finish the last piece of the jigsaw.

VS 2010 Filling 2 Comboboxes, 1st Determing Data For 2nd?
Mar 27, 2012I am having difficulty trying to fill two different comboboxes (cbo) with data from a database. More accurately, the 1st cbo gets filled correctly, but when I attempt to do something similar with the second, I'm getting an error about not being able to use the & Operator in my SQL string (Operator is not defined for string and DataRowView types). So evidently the SelectValue from my combobox isn't acting the way I expect.
The overall goal of what I am attempting to do is to fill two cbo's, one with a list of contracts and a second as a list of parts given the selected contract from the first cbo. There are 3 tables in the database that I am drawing the data from: the "contract" table, the "parts" table, and a bridge table called "partList" that has foreign keys pointing to the two other tables. The first cbo is a basic query to the "contract" table using "ContractName" as the display member and "idContract" as the value member. The 2nd cbo I would like to display the name of the part from the "parts" table but use the id of the part from the "partsList" table, and to further filter this list based on what contract was selected.
I am writing the code in VB.Net from VS 2010, storing the data in a MySQL DB, and using a DBFactory to create all the components from ".GetFactory(MySql.Data.MySqlClient)"Below is the code that has the two places I am attempting to fill the two cbo's. Also if there is a better way to handle this, please let me know.

VS 2010 - Filling DataGrid Columns With Excel Data

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

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?

How To Stop Controls From Updating With Data
Nov 1, 2010I have a form with many controls that are binded to a datasource. when some of these values change, they impact aspects of the form itself like the backgroud color or the title. There is a filter applied to it so it only displays certain records (this is important).when I change something and save the data I need to update the filter to show all the previous records plus the current one.All that works great, but the problem is: saving the data or changing the filter makes the controls take a new value based on the new record and go through the subs that each one have to modify the aspect of the form. This happens because if I save the data first, then the current record does not conform to the filter and all the data in the form changes, or if I change the filter first, we go to the first record of the set.
After that I return to the correct record and everything looks fine, but going to all the changes makes the app halt for a moment.Is there a way that I can stop the controls in the form form updating to their binding data while saving or changing the filter in the bindingsource?
