View 3 RepliesI 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.
I have a readonly datagridview that is bound to a datasource. It has two columns. Now I want the first column to have no cell borderstyle; and the second one to have 'All' (i.e. all sides of the cell shall have a border) as cell borderstyle. Before binding the datagridview to the datasource, I'm writing something like mentioned below but it's taking no effect. Assume the column in question is named DisplayName.
Code:
Dim newStyle As New DataGridViewAdvancedBorderStyle()
With newStyle.Top = DataGridViewAdvancedCellBorderStyle.Single
.Left = DataGridViewAdvancedCellBorderStyle.Single
.Bottom = DataGridViewAdvancedCellBorderStyle.Single
.Right = DataGridViewAdvancedCellBorderStyle.SingleEnd With
DisplayName.CellTemplate.AdjustCellBorderStyle(newStyle, newStyle, True, True, True, True)

I've got a window with multiple datagridviews. Each with data from a separate dataTable. All of which are part of the same DataSet. There are a couple of places where one DataTable has a field joined with the lookup dataTable from the dataset. For example a lookup table for LugSizes has a field called LugSize that is also it's primary key. Another table called Device Terminations has a field called LugSize to which the user can only select those values from the LugSize lookup table. I thought it would be as simple as using the Items.Add method for the combobox column whenever a new lookup table row was added to its own datagridview. Unfortunately, when I try to initially clear the items list, the data error event is triggered for every row.
Here's a sample of my code if it helps:
HTML
Private Sub FillLugSizeComboBox()
Try
If colDTLugSize.Items.Count > 0 Then colDTLugSize.Items.Clear()

I need to be able to change the font of a label, to bold.I know it's very simple but i'be forgoten.I've tried: Form1.Label1.Font.Bold = True but i get the error: Error: Property 'Bold' is 'ReadOnly'
View 2 RepliesI want to change the font on a button to bold after certain conditions exist during runtime.
I tried
Col1Button.Font.Bold =
True
The autocomplete allows me to type it, but it doesn't work. There is an underline under the IDE code. Font is apparently a "Read-Only"property. Is there a way to make it a changable property?
I'm new to VB in Visual Studio 2008 and am just trying out some simple test.I just want to change the Font & Boldness of some text but get the following errorProperty 'Size' is Read onlyI have been browsing the forums and it seems that changing the font size etc isn't as simple as
TextBox.Font.Size = 12
TextBox.Font.Bold = True
Is this true, and if so what do I need to do

I'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:
Dim row As New DataGridViewRow
row.CreateCells(Datagrid)
and the column using the following code:
Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)
I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:
arow.Cells("Reference").Value = Detail.Reference
However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?
How to make datagridview current row bold?
View 1 RepliesHere is what I need to do: I need to be able to go through the cells in my first column and find any that have four digits (and only four digits). When a cell is found with a four digit number I need to be able to bold that entire row. How can I do this?
I'm in VS2007. This is a datagridview program. Data populates the tables from a database. The cells in the first column that contain the data can contain between four and 8 numeric digits. I only want to bold the rows that have cells in the first column that have four digits.

View 1 RepliesIs it possible to change the icon of my app in runtime?
View 8 RepliesIm writing a app using vb.net, which has multiple front ends e.g a windows service and a windows forms app. Ive got all my business logic and database stuff compiled into 1 project (producing a dll) then the different front ends as different projects calling the dll.
In the backend / dll project Im connecting to 2 databases using app.config to store the connection strings and DataSets / TableAdapters. This all works fine .... Until
When I deploy the windows app, it deploys the exe and the dll produced by the backend project. when its installed on a client PC, Im need to point the app at a different db server and therefore need to change the connectionstring, but its packaged up in the dll.
is there any way I can use a settings file within my windows app (therefore deployed with my windows app) where I can define the connectionstring, which onload gets passsed through into my dll, so the backend connects the correct database. I know how to pass standard settings through (strings etc) but the my.settings.connectionstrings seem to be readonly.

View 27 Repliesi have a program i've made a while, and one of the users wants to be able to load his own images to the background instead of the plain grey that is there now. i've searched and searched, and basically can get this working
BackgroundImage = Image.FromFile("C:UsersMeFileName.png")
i just slapped that onto a button just to get it to work as i was experimenting. but that only works for a file of that name, on my computer, in that folder. what i'm looking to do is get it so a user can browse his own directories for images and upload them as the background on the form. and be able to save the settings as well. but so far i have only seen different ways to load preset images that you can load. if it's even possible? i'd assume that you'd use the openfiledialog command, but i'm not that well versed in vb as of yet.

I have a forms application and I have multiple localizations for it. I've figured out how to add a button to a form, to change the localization and then read all the labels/etc and change them to the other language.What I would want to do instead now is click a button and it changes to the other language the current form but also the entire application so that any other windows opened while the application is open open in that other language.[code]This is the code I use when a button is clicked on a form to change it to Hindi the current form. However I want to when the button is clicked, change application to continue to run on that localization instead for the remainder of the time it is open.[code]
