• Visual Basic hiding the startup form

  Hi, I was wondering if there is a way to immediately hide the startup form on startup. The Me.visible = False and Me.hide() Methods don't work. I am trying to make a simple program that has a login form and the main form. When my program starts i want the login screen to appear and the main form to immediately disappear, then when the user clicks OK the login screen closes and the main form shows. Everything works except when the program runs both the login and the main form window appear and i can't seem to make the main form disappear, and for other reasons setting the login form as the startup form is not an option. Hope this is a simple fix. Connor 1. From Solution Explorer, select "My Project&qu ...Show All

• Visual Basic LEFT string function

  This is how you would use the LEFT function in VB6 ... str1=LEFT("This is a typical string",4) Can you still use the LEFT string function in Visual Basic 2005 I can't seem to get it to work. Hi, Terry,   MS.VB is essentially already imported, as is the System.Windows.Forms namespace.  Consequently, adding an import won't help you here -- they're just two imported namespaces which happen to have conflicting members (as might happen with any arbitrary imported namespaces).  However, you can set up an alias like: Imports VB = Microsoft.VisualBasic and then the call would be VB.Left, which is a lot easier to type.  (You can substitute whatever you like for "VB" ...Show All

• Software Development for Windows Vista Modifying custom composite activities at design/runtime time inside of a workflow.

  If I create a composite activity that inherits from SequentialActivity and has a number of other activities added to it and drop this new activity on a workflow is it possible to modify it at design time. So if one of the sub-activities I dropped on my composite activity was a sequential activity can it get modified after it is dropped on to the workflow. Basically what I want is to be able to create custom activities with certain common flows but at some point I want to be able to put a place holder in that flow to allow someone reusing my custom activity to do something custom. 2nd question related to the first. Same situation but instead of a placeholder (i.e. sequential activity) inside of this custom activity I want to use an ...Show All

• Windows Forms Newbie - ToolStripMenu not displayed fully .NET 2.0

  I have eleven ToolStripMenuItem choices ( parents are a MenuStrip) that display horizontally correctly on my MenuStrip at a resolution of 1024x768. When resolution is changed to 800x600, only the five leftmost items are displayed. Is there a way to "scroll" the MenuStrip horizontally or some other best practice to allow the user to access to the other menu choices at the lower resolution Thanks ga2006 wrote: Is the MenuStrip's canOverflow property related to this issue as well It certainly looks this way - overflowing ToolStrip items works, but this isn't the case with MenuStrip items. Instead of showing the dropdown combo on the far right (as is the case with the ToolStrip), th ...Show All

• Smart Device Development Disabling ClearType in an application

  Reading the WM5.0 doc, it states that ClearType can be enabled system-wide or on a per-application basis . Can someone tell me how to disable ClearType on my application only, as I want to use DrawString to draw non ClearType text I tried using logfont with: logfont.Quality = Microsoft.WindowsCE.Forms.LogFontQuality.NonAntiAliased but the result is still a clearType drawn string. Help Gavin Hi Gavin, The current behavior of WM 5.0 is to set the ClearType bit on a font when it is selected into the device context. The ClearType bit is set if any one of the following is true: CLEARTYPE_QUALITY is set in the LOGFONT or CLEARTYPE_COMPAT_QUALITY is set in the LOGFONT or ClearType is enabled s ...Show All

• Visual Studio Express Editions Innate memory leak with C#?

  Hi, I've been doing some testing with C#, and it seems that innate to the language is a memory leak, or so it seems. If you create a completely blank form, and run it, when you move the mouse over the form, memory usage slowly increases until it finally peeks out at about 700k. As you I add more and more buttons, labels, and other things, this number slowly increases. Right now my applications memory usage slowly increases until it peeks out at 1200k. In order to see this increase, you do have to continually move the mouse over the form. Has anyone heard of this before What is the cause and is there a way around it Here is sample code I used to create the blank form: using System.Windows.Forms; namespace ActiveXTest { public class For ...Show All
