How do I force FormatNumber to use a "-" to separate every "000"
Depending on my users culture on their computer
the result looks like "123 456 789.1235" or "123,456,789.1235"
How do I force it
Dim A As Decimal = "123456789.123456"
Dim B As String = FormatNumber(A, 4)

View 4 RepliesI created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

View 2 RepliesI've got a handful of dynamic controls populating an ASP page, with VB.NET in the back-end.What I need is when the user changes the .TEXT value of a textbox and the page posts back, the .TEXT value of a Table Cell changes to reflect that change (it multiplies the value of the textbox by the value of another cell).But a Table Cell can't be set to AutoPostBack, and I can't for the life of me figure out how to programmatically refresh the page (force a postback) in the TextChanged event for the textbox.

So, my application has multiple text boxes for entering different numbers. Only numbers..
One problem I've run into is that I get an error when a textbox is totally empty. If I throw at least a zero in there, it works fine.
How would I make a textbox display "0" when someone deletes everything in the text box? I don't want it to be empty, I just want it to show zero.
I have written an application for a customer, and the application is run in various locations around the world. The company carefully controls the release of the software to the various buildings where it is being used, and because of this, I have made use of the "Check for updates" feature. The problem I am faced with, is that the folks using this software more often than not answers "NO" when prompted to download and install the latest version of the application. This is unacceptable and ultimately, we'll need to go in and have them manually install the software.
We don't publish updates to the software w/o meaning for them to be necessary, and I find it hard to believe that Microsoft doesn't recognize this sort of thing as being needed when they designed the update procedures. Alas, this seems to be the case.
I'm having an application which has to perform exporting and importing data. At the moment he runs those functions, I want a form to popup with an animated gif, so my client sees that the application is still running.But the animated gif stops sometimes, because he is busy doing stuff (like copying files, etc...)Is there a way to tell the form to refresh automatically every 0.1 sec, so the image runs fluidly. I tried to put a timer in my form, and start the timer as from the form is shown...the timer_tick says he has to refresh, but he doesn't want to do that.

I am having a bit of trouble converting a single stored in a string as four hex values. I believe my problem stems from some Unicode hex values not matching the corresponding ASCII hex value above 0x7F (127). For example, I have the following single stored in a string; "518.42" or 0x44019AE1. The char that would contain 0x9A if the data type were ASCII contains U+0161 which will not convert properly to a byte array. My question is: Is there any way to force a string to be of ASCII rather than Unicode? Or maybe there are other recommendations? For reference I have tried both of the following. The first throws a format exception and the second converts to the wrong single.
Private Function ConvertHexToSingle(ByVal hexValue As String) As Single
Try
Dim iInputIndex As Integer = 0
Dim iOutputIndex As Integer = 0

I have a DataGridView which I AllowUserToAddRows behavior enabled. I want to be able to force that only one row be added at time, then if the user clicks the save button the row is inserted into the database, and then another row may be added if the insert was successful.
The reason I want to do this is to get the last inserted id and insert that information into another table.
I ran into a little problem where my thread(s) tries to access a control that may not be created yet. How can I check for this or is there a way to force the creation of the control(s) first and then go on or any other solution?

Is there a way to force a form to reload itself? The reason I ask is I have a listview that shows the data from my database. You can add information to the database from another form but when you go back to that form the information is not updated because the information updates on the form load. So my question is there a way to just do the form_load event again?
