View 2 RepliesI have an application which uses hotkeys which are to be defined by the user. It is a combination of 2 keys, either CTRL, ALT, SHIFT as one hotkey and the F* Function keys as the other (e.g. CTRL + F1, ALT + F2 or SHIFT + F8) As stated these are then chosen by the user before a global keyhook is put in place to listen for them and trigger an event. In my app I have all my function keys as follows:
Public Const VK_F1 = &H70
Public Const VK_F2 = &H71
Public Const VK_F3 = &H72

I've got a VB.Net form application that dynamically loads user controls based on which navigation link the user clicks on. I'd like to make it easier to use at Design time by putting a link of some sort to open the User Control at design time. The link would go onto the form in the space where the User Control will be going. This just saves a little time from having to browse through the files to open the correct file.

I've searched for a solution with no luck, can you help? I've a DataViewGrid with a DataGridViewComboBoxColumn, bound to a dataTable which all works fine but I need to undo the user selection in some cases.
When the user selects one of options I validate that the chosen option is appropriate for the rest of the row. I can do this in the CellValueChanged Event and easily determine if its good or bad - is this the correct event to do the check?
The problem I have is that I want to roll back to the default value in the DataGridViewComboBoxColumn if an invalid selection is made:

I am currently working on a menu driven console program that so far has 4 menu options of checking internet connection, decrypting/encrypting a message, calculator, and a logout, and i am wondering about a few current things.
1. How do i make it to where, when a program starts for the first time, it asks for a user to enter in his data, like signing up for a site for the first time?
2. How do i make it to where the program will save the data entered, and does not delete when the user closed the program.
3. How can i make it to where when a user signs in, his/her data is read correctly? Like an array search for a multidimensional array.For my "New user" sign data i created a function...
Function createNewUser() As String()

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.
View 1 RepliesCan a media player written in VB be modified to do this: randomly choose an avi file from a directory or subdirectory, choose a random starting point within that file and then play a clip of a random length (within user defined parameters) then without prompting repeat this sequence?
I would like just such a media player but there doesn't appear to be one already out there so my only other option is to write one myself. I know nothing about VB and last programmed in BASIC in the 90s. Before I invest time and effort in learning VB I need to know if it can actualy do this at all.

View 9 RepliesI have created the random bingo calls needed with the standard bingo letter restrictions.. i.e. B = 1 - 15, I = 16 - 30, etc. I have a form with 5 columns with B I N G O at the top and the corresponding numbers beneath. Those are labels named lblB1, lblB2, etc.
My problem is that I can't seem to figure out how to get get the text to change on the called tiles. Logically it would be easiest to use something like
varLabel="lbl" + varCalled
varCalled.Forecolor = red
Where varCalled is the ball number being called.But.. that is not the case. (I'm at work so can't submit the actual code at this time.. will do so later if needed)I've done some searching and can't find anything that helps out.. but searching for "change label color dynamically" comes up with how to change the color of a label at runtime.. not sure how else to search on it.
I am using combobox to populate values from a table, 'Suppliers'. I put this combobox in a form wherein the order details are filled up. This column 'Supplier' is a Foreign Key and set to NotNull in the order detail table. Selecting the first available entry on the combobox gives error 'SupplierID cant be Null' . Selecting the 2nd value is OK, first choosing 2nd and coming back to 1 is also OK. This error comes up when trying to update the database.Even with the first value, the combobox is having a text. I would like to know why the error.
