Format DataGridView Column - Code39 Barcode?
Apr 12, 2012
I want to use barcodes in to my application in VB 2010. Also, I am a beginner in VB programming.I made a simple application. I fill a DataGridView form an SQL Table. After that i must apply a filter, and then print the form.I managed to filter the data from that DGV, but now i'm stuck at making that column to show barcodes instead of ID number.In the DataGridView, in the first column of the table, it's the ID column. In SQL this colum is set as "int"In this column are unique ID Number, and I want to convert those numbers into barcodes (Code39 - I have this font installed).
I set the font of that column to be Code39 font, but this barcode needs symbol before and after the ID number, like this: *1234* , that it can be read afterwards by a barcode scanner.How can I put those * in the ID Column ? It can be done adding a CellFormating Event?

I have a datagridview on my form that has 3 columns - Area, Rate, and Sq Feet. I want to display the values in the Rate column with dollar signs. Is there anyway to do that? I am using VB.net 2005 and ms access.dvRepCost holds the data returned from my select query and is assigned to be the source to my datagridview.
Here is my
dvRepCost = CType(MyController.ScreenHashOutData.Item("RepCostAFI"), DataView)
Me.dgvRepCost.DataSource = dvRepCost
dgvRepCost.Columns.Add("Total", "Total")
[code]...
I've also attached a screen print of what my datagridview looks like at runtime.

I have a field defined as string for phone number which in my SQL cast to Integer.
Format the column as follows
DataGridView1.Columns("ContactPhone").DefaultCellStyle.Format = "(###) ###-####"
This works as expected for cells with a phone number but for cells without a phone number I get
{}- Which seems like the proper output for what I specified.
is it possible to format cells with no data (no phone number) to show up empty in their cell?

I have a datagridview populated using a csv file. I have a column named Date. The csv file has mixup of different date formats. So I need the date column in datagridview to be in standard "MM-dd-yyyy" format. I used below code
Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "d"It didnot have any impact.
So I used the below shown code Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "MM-dd-yyyy"Still no effect.

With my datagridview I have column for datetime. I used the following for format.
Mydatagrid1.Columns(3).DefaultCellStyle.Format = "dd/MM/yyyy"
But the problem is it's getting input like MM/dd/yyyy and after pressing enter it's changing to dd/mm/yyyy style. So is it possible to read input like "dd/MM/yyyy".

I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

I am using Richard L. Grier's Enhanced Serial Port dll to read input from a serial port barcode scanner I notice that the datareceived event fires only once per barcode scan, but the delegate sub fires twice per barcode scan. Once for 1st half of Barcode , 2nd for 2nd part of barcode This makes it hard to capture the full barcode so it can be passed to routines in my vb.net 2008 windows application In Richard's example 'Test Enhanced Port' program he sends it to a textbox using .selectedtext and it works fine Richards Delegate code ......................
Public Delegate Sub DisplayData(ByVal Buffer As String)
'This delegate routine marshals receive data from the receive thread context DataReceived to the Windows Form STAThread context
Private Shared Sub Display(ByVal Buffer As String)
[code]....
I am trying to set a variable to the full barcode to pass to routines, instead of writing to a textbox but am not having any success

I am a student and I am about to make a program that will use a barcode scanner well ofcourse to scan a barcode. My problem is i don't know what library to use and what certain things i need to do so that when i am going to scan a barcode it'll be something like show it on a textbox and pull something from the database. i've actually research some. i've seen mscomm1 (not so sure about that) and POS for .net (haven't fully understood its use) were those will help me develop my program?i have a metrologic ms9520 Voyager barcode scanner. and i am going to create a program for it in vb2005.

I am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime

Is there a way to find the column index of a datagridview column using the columns DataPropertyName?I currently use a loop (shown below in the class) which is kind of ugly, but it works. I'd like to do something like this, which seems more elegant.My goal is this, I store the users DataGridView column settings (i.e. DisplayIndex, Visible, & Width).When the user opens the form that contains the datagridview I want to get those settings from the database and apply the settings to the datagridview.[code]
