Imply A Command That Affects All TextBoxes In The Application?
Aug 10, 2011
I'm wondering if there is a way to write a code that affects every single TextBox in my application... I have about 12 Forms that are all inherited from my BaseForm. I want to affect all of the TextBoxes in those 12 forms The idea is, that every single TextBox would change the text in it to Bold, if the text is not 0 or 0,0 or 0,00. Let's say there is a Form that has about 100 textboxes to indicate different values. Every TextBox that shows the value 0 should be in normal font, but every TextBox that shows any other value should be bolded...
Or should I just do a public function that is called every time a textbox changes value? (Not quite sure how to do this either...)

I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).
I can only access the external program thru the command line (its not my program) and I must do so from a form app.
I am trying to use the following code. I am able to call a cmd.exe window, but I can't pass the command line my command.
Using mp As New Process
With mp.StartInfo
.FileName = "cmd.exe"

I have several textboxes in a form, and have a button which inserts all the values in a Database and I have to clear the content of all the textboxes and focus to the first one right after pressing the button.Now I can easily do that using the Clear method of each of the textboxes but it takes 10-12 lines of code just for that. Can I do that in one go?

I have this picture to be more clear. My idea is when I paste (ctrl+v) for example this number: 4111111111111111. It would automatically paste them in textboxes one by one in order!
so txtBox1 will contain : 4111
txtBox2 : 1111
txtBox3 : 1111
txtBox4 : 1111
The automation of inserting credit card's number will ease so much. So that user will not work so hard to cut & paste each four digits!dy in txtBox4 and want to delete back with the key "BackSpace/Return". After deleting txtBox4's content and clicking one more time the "RETURN' key it would move to txtBox3 and so on until cursor gets to txtBox1...

I am working on an app that is an MDI. When the user clicks a button on an MDI child, I want to "disable" the current MDI child (and only the current child window), open a new window that has control, and then re-enable the child window when the new window is closed...very similar to using showDialog(). The thing I an having trouble figuring out is how to allow the other child windows to be active at the same time as when the new window is open. If I use the showDialog(), all child windows are disabled

In teaching myself how to use databases in VB applications, I've managed to
1. Get list box data bound to a database
2. Filter number of items displayed in list box based on user input (letter entered as a filter)[code]...
How can I now have it so that the user selects an item in the list box, and then text boxes on the same form are populated with the relevant data (i.e. database fields matching each text box, with another field from the same table having already been used to populate the list box)[code]...

I am currently creating the classic Pong game in VB.Net. I have a few questions regarding angle of approach and rebound.
For example if the ball hits the wall at roughly a 30 degree angle then it should roughly bounce off the wall at ~30 degrees. This is my first query, how would I achieve this as I cannot figure out how. It is currently bouncing the ball off the wall by altering ballXspeed and ballYspeed by 5 or -5.
My second query is that of the ball hitting the paddle, if the ball is to hit to top 0% - 5% of the paddle it will bounce off at a different angle opposed to if the ball hit the paddle in the 15% - 20% zone of the paddle.
Here is my code in its entirety:
Public Class Form1
Dim ballXSpeed As Single
Dim ballYSpeed As Single
[CODE]...
I understand that you cannot do the work for me and I don't expect you to. Would it be possible for help with the pseudo-logic or a particular area. I forgot to mention that the ball currently bounces off the paddles at a random angle.
Hence:
ballXSpeed = -5
ballYSpeed = New Random(DateTime.Now.Millisecond).Next(-10, 10)

Basically I have an application that has 2 textboxes and a button. What I am trying to do is when the button is clicked, it takes an entered string from box one (which is validated to only accept numbers) adds 235 to it then converts it to hex and finally reverse the string and sets textbox two equal to that value. Note that the final string has to be eight digits so the string may needed to be padded with zeros before the string is reversed. With that said how could I go about doing this? Also I do plan to add 2 more textboxes and another button to undo this process but I am thinking if I can figure out do it one way writing the code to undo the process shouldn't be too hard.

OK! I've written my application in all it's GUI glory. I now just want to be able to run it from dos/a command line/batch, with no GUI appearing? So it just runs (& does its batch process).
How can I detect if my application has been initiated from command line/dos?
How do I then not open up the application and show its GUI etc?

I can connect to the database and view the tables, but I have'nt got any idea how to get the data from the fields in the tables into the appropriate textboes on the application forms.

I am building an application where on a form is a datagridview and textboxes. The dgv and tb are bound to the same table. I am using the dgv to have an overview of the records and the tb I use for editing. Selecting a record programmatically in the dgv is no problem, but the textboxes have to be filled with the same record. Here I have added my code to this far.
If OuderID <> 0 Then
'select the row
For i As Integer = 0 To dgvOuders.RowCount - 1
If dgvOuders.Rows(i).Cells(0).Value = OuderID Then
[CODE]...
I am stuck right now. I want to add (on the dotted line) an performclick action, but a dgv doesn't have a performclick action.

I'm currently in the middle of a Console Application. I have done everything and it's ready to be handed in. However, I don't want to hand it in like this. I want to build upon it.
One of the ways I'd like to build upon this is with an e-mailing system. I'm find it hard to include the e-mail code in to the project and would like to request assistance. I'm uncomfortable posting the full code on the net as it is for my A-Level Computing and anyone that is doing the same course as me will be able to claim it to be there own.

I want to exit my GUI application (vb.net 4) using a commandline parameter.I should send thive! from the commandline:
myapplication.exe quit and an already running instance of the application should exit.
Now, I have a mutex detection in place so that I can only have one instance of the application running at a time. It seems that if I send a commandline, it won't work on an already running application; it will only work on one that is launching.

Is it possible to restart a VB.NET application, but with different command line arguments than it originally had? Here is the challenge. I want to write a single instance application. If the second instance has the same CL args as the first, then the built-in behavior is fine (second instance never opens, e.BringToForeground=True brings 1st instance to foreground, everything is great). But if the second instance has different CL args, then I would like the first instance to close and the second instance to start. However, once you mark a VB.NET app as "single instance only", it appears that you can never get the second instance. I think: OK, fine, I can just restart my first instance from the StartupNextInstance event. But how do I use the new command line arguments from the second instance? The Restart() method does not take CL args that I can see.
