• Visual Studio Express Editions Please Help: code for timer events is stuttering

  I'm almost finished with my first VB program, yet I'm not too excited about it. I have a problem I can't seem to fix. My program has two timers: one has an interval of 1000 and I use it to count down seconds. The other timer has an interval of 100 and it's used in a code for a stopwatch that counts in tenths of a second. The problem is that both timers stutter, something especially obvious in the one for the stopwatch, making my program useless - if you can't trust the stopwatch, then what's the point. The timers never run simultaneously and they are in different forms. Here is the code I'm using for the stopwatch <code> Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick ...Show All

• Windows Forms Problem with Visual Inheritance when i change the size of the Father form

  Hello I have a form called FormMain - this form has controls on it (some are windows controls and other are infragistics controls) I changed the private void InitializeComponent() of the FormMain to public void InitializeComponent() in addition, i changed the decleration of the controls on the form from private to public Naturally i have done all this so i could inherit from FormMain (i know that i should have changed these to protected rather then public but when i change it to protected it doesnt work , found there's a bug on this) On any case, in my formMain i adjusted the size of the controls in the designer the way i wanted them Now i created another form called FormMainTester which inherits from formMain, the pro ...Show All

• Visual C# Can anyone give me an answer to this?

  Your program will be fed 800 distinct numbers from of a range of 8001 to 9000. You need to store these in-memory and then print. How would you do it Thinking of an array of ints Well, that would need around (4 x 800 = 3200) bytes. Can you reduce the required memory further (by more than 20 times) Regards Mani Thanks for the answer Anomolous There is a bitarray class which does the job cleanly By the way, I could also have boolean array if system stores bool as bits. Does bool take one bit Regards Mani ...Show All

• Visual Studio Express Editions Replacing an empty element in an array, with the element above it.

  I'm making an rpg, and I'm working on the vender system, and I have an array , called Slots[32], there are 32 inventory slots, this allows blank spaces, I'm not actually sure if C# counts the elements differently, if I dim it as 31, I should have 32 slots, counting 0, but it says its out of bounds when I do that...Anyways, the slots array just holds the name of an item, armor, or weapon, with that, I get the picture I need from a file by looking up the name, that part works great.  But when I try to use the same thing for the 'buyable' as I call it, it will end up a few spaces down, heres how it is set up, in the selling tab, there are 32 'buyables', I have a method to hide everyone that has a null text value, and show everyone that d ...Show All

• Visual Basic Sub Main in Mainform.vb never getting called.

  If I create a Sub Main in my app, the app never calls it. No breakpoint hit, no Messagbox shown. Thanks for any ideas. -greg MainForm.vb Friend Class MainForm Inherits System.Windows.Forms.Form Sub Main (ByVal cmdArgs() As String) MessageBox.Show("main") End Sub End Class MainForm.Designer.vb Partial Class MainForm Inherits System.Windows.Forms.Form You DMan.  That makes perfect sense. The reason why why want to use sub main it is to put control instantiation code prior to the forms initializecomponent. Why Because with testing, the app I am porting to .net 2.0 paints just fine with a plethora of controls, between suspend and resumelayout. ...Show All

• Visual C++ How can I prevent my application from being launched multiple times simultaneously?

  Basically, I want my application to detect whether it's already running and shut down if it would be the 2nd copy. I think the solution might use COM objects, but I can't make any sense out of the COM documentation in VC++ 6.0. See the code below. I patched this a couple of times over the years to handle WinXP where you might have multiple users logged in (via Fast User Switching - does anybody actually use that ). It also sets focus to the existing instance before exiting. Note that I use two mechanisms - one that enumerates existing top level windows (looking for my expected program name in the title - kind of a kluge) and if that fails it uses a global instance of an object. Seems to work f ...Show All
