My problem is I do NOT want to have multiple calculators running even if i click the button more than once.

View 1 RepliesI want to use calc.exe file in my vb .net program. I was trying this code but it not works as what I want.
Private Sub CalculatorToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculatorToolStripMenuItem.Click
Dim startInfo As System.Diagnostics.ProcessStartInfo Dim p As New System.Diagnostics.Process
startInfo = New System.Diagnostics.ProcessStartInfo("calc.exe")
p.StartInfo = startInfo
p.Start()
p.WaitForExit()
When I click the menu to use the calculator, my system seem to hang and the background process is stopped.
What I want is, when I click to use the calculator, the background process is not stop. I only want we cannot touch the form at the back, I meant we cannot click the function at the back form untill the calculator is close. The calculator also should locate at the top of the form and cannot be minimized.

The picture is a graphicspath drawing a curve through the specified green dots... the red points are the Bezier points that are auto generated by the graphics path.
Basically I want to pass in an array of points (in this case the green dots in the pic) and get an array back of the Bezier (red points) - I want to calculate the location of these points MANUALLY - and not use the graphicspath object to work it out.
It doesn't have to be exactly the same just similar.

However, it doesn't let me add more values to the list. Any help whatsoever would be awesome! Keep in mind, I am new to VB and programming languages, and was just playing around with code hoping for any sort of positive result, and therefore some of the code may not be necessary, or make sense.

I am in process to develop an application for Windows Mobile 6.5 using Visual Basic 2005 and .NET Compact Framework. My problem is that I want to know if an instance of my application is already running and, in that case, I want to jump directly to that instance, without starting another one. I tried several solutions found on the internet but I think there are solution for desktop applications not for mobile applications because I have a lot of errors.
View 1 RepliesI spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.

View 5 RepliesMy application has a form which contains several Textboxes where user is required to fill up data. Once data is filled up user can click on "Save" button to save the data. I have added lost focus events to all textboxes so as to validate user input. When I click on cancel button, i want to detect cancel button click, but textbox lost focus is fired first so I get error message for textbox before my code moves to cancel button click handler. Is there any way to detect button click before lost focus event?

I have created two user controls (lets say A and B) and calling then on default.aspx. Both user controls have button named as clear and its event method "btn_clear_click (sender,event)". Actually I like to do something like this: if I click clear button of user control A then it would also do the same tasks defined in user control B's bth_clear_click method. Means, is there any why to call button event of one user control in another user control.
