I programatically / runtime created combobox and bind it to a datasource but can not set its default value. Since I am using the Handler of SelectedValueChanged, this is causing the program to mis-fire. Here is the code I am using.
Public WithEvents T_combo as ComboBox
'dictionary holds data to use in other parts of program
Dim T_Dict As New Dictionary(Of String, String)
[Code].....
I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default. The name is stored in a public variable 'PubName' and I do not want the user to be able to type into the combobox themselves.Is this possible?

Is the default format of ToString dependent on anything server related? Here's the issue: I'm testing and have tested an application on my local machine and ToString(), by default, is returning in a format of "MM/dd/yyyy hh:mm:ss tt", however on our server it appears to be returning as "dd/MM/yyyy hh:mm:ss tt" which the consuming application is not expecting and causing errors.
Dim uvExpireDate = DateTime.Now.AddMinutes(1)
Dim token = String.Format(fmtString, uvExpireDate.ToUniversalTime().ToString(), [various other params])
I am trying to set the "ColumnHeadersDefaultCellStyle" property to the "GoudyHvyface BT" font and it will not change from the default. I am using Visual Basic 2008.
I have set the property properly with no success.
I have tried to set the property in code, using the suggestions in the MSDN and it kept throwing errors.
So I made a little program, and when I run it on my computer the Date format displays as DD/MM/YYYY, but when I run it on some other computers it displays as MM/DD/YYYY. Is there anyway to set the default incoming Date format? Or do I just have to be very careful about how I get/set parts of dates?

View 1 RepliesI am creating a customised version of the ListView control and there are several of the properties that a ListView has that I would like to be set to a different value to the ListView default when a user goes to use my user control.
From what I've found there seems to be a number of people suggesting just set them in the constructor, but to the best of my knowledge that would just mean that the user would not be able to change the properties in the PropertyGrid in the VS IDE.I assume this is probably something extremely simple that I have overlooked.
I have a label printer with the driver loaded with the settings in the driver set I can print the exact label that I want, I have the problem that I need to set the default settings in the driver when the software starts. there are 6 of these printers and the only problem we have found is that different operators like to change the settings.
What I need to do is to set the following commands in the driver so each time the system is started (daily) it loads the settings and works properly.
I need to set
Custom Commands Text, Start, Parsed Text
In the Advanced Setup, turn on use printer settings
Other settings would be usfull but as I cannot set these I do not think I will be able to set others.
I can currently set some of the commands eg,
DefaultPageSettings.PrinterSettings.Copies=2

View 3 RepliesFor some reason when I place a button on a form and type some text, the text is too big for the button. Descenders are not shown (i.e., the bottoms of g's, p's, q's, etc.). Does anyone know how to modify the default settings of the button, such as the height or font size? Obviously I can change these properties after I place the button on the form, but this gets old. My default font size is 7.8pt San Serif. If possible I would like to increase the default button height and the font size (I like to use bigger text for teaching in class so those in the back of the room can see).

View 10 RepliesI am kind of an old 'newbee' at this, so bear with me for a moment. I am developing a windows forms application in Visual Studio 2010 Professional that connects to a remote database (MS sqlServer 2008 R2).To speed up development, I configured a DataSource and used the data objects associated with it. In VB6,
the data source could be assigned to the data objects during runtime using a variety of different runtime database connections, ODBC, ADO, ...
I have been unable to find a similar method with the VS2010 Visual Basic DataSource and underlying TableAdapter, BindingSource, BindingNavigator, down to the individual ComboBox and assorted other bound controls. It's convenient to have the integration, but I've got different users with different permissions, The long and short is that I'd like to be able to assign the data source during runtime operation, at least to the connection string level.

I am trying to get the button on the visible panel to be the DefaultButton so that when Enter is pressed the click event is fired off. The issue that I am having is that I get this error no matter what I try: The DefaultButton of 'form1' must be the ID of a control of type IButtonControl.I have tried setting the Default Button property of the panel to the buttons client id and to its unique id.

Just started using the Windows Browser in one of my forms so the user can select a photo they need to load. This was surprisingly easy (This seems to be the norm in Basic, if you think it will be hard it isn't and visa versa). What I am struggling with is how to set the default location to 'Computer' rather than a disk letter and directory name. The photo is most likely to be on a card reader or Memory stick so the drive letter is likely to change.
I am guessing the command will be:
OpenFileDialog1.InitialDirectory = ???????

View 7 RepliesI've added some Labels to a form at runtime using this
vb.net
Dim x As Integer = 25
For i As Integer = 1 To word.Length
[Code]....
Now, I would like to add text to one of them, but I'm not sure how. I thought by setting .Name I would simply be able to write something like lbl4.text ="A". But, of course, because the Label has not been created yet, this is not possible.
Also, I'm not even sure if .Name is working the way I think it is. I was hoping that it would name each Label consecutively: lbl1, lbl2, lbl3, lbl4...etc.
Am I naming the Labels properly? And how would I add text to one of these Labels?

On exit, (for learning sake on my end) I would like to have it set back to the default.
