• Windows Forms Assertion Failed! Handle has not been created.

  Hey,   I have recently been working on a tutorial application using C#, and between each "slide", I need to fade out the current slide's controls and fade in the next slide's controls. To do this, I created a new control, and added a FadeIn and a FadeOut command. I successfully added the fadeout command, and I escentially mirrored it to make a fadein command by copying the code and switching out the variables. Now, here is the problem that I am having. At program execution, this code is called to fade in my first screen: [CODE] Debug.WriteLine("Fadein() Called");         Debug.WriteLine("Fadein() line1") ...Show All

• Visual Basic How to use DataGridViewControlCollection in place of Control Array of MSFlexGrids

  Hello, I am learning VB2005 by rewriting a large VB6 program. My VB6 program used loads of MSFlexGrids in a single Control Array. Control Arrays are out with VB2005 so I was looking at a way of using DataGridView controls in the form of a collection. The MSDN documentation points in the direction of DataGridViewControlCollection but I cannot decifer how to add DataGridViews to form a collection and then how to access each one in a similar fashion to my VB6 Control Array. My VB6 program loads the MSFlexGrid's in this simplified fashion: For I=0 to MaxFlexGrid With MSFlexGrid1(I) Code to load cells Next I Is the D ...Show All

• Windows Forms Yet another Toolstrip question.....

  I have a really large project around a toolstrip. It already has several thousand lines of code to support all the dynamism I want. I run toolstrips through many conceivable configurations. I put them through flow mode and change their stacking etc. Now, I'm seeing something new that I have not seen before. The toolstrip separators are horizontal and look like hyphens instead of the nice vertical separators.  A drop down button gets very small and is only the size of the arrow head. Once they do this, I can't get them to appear as they used to. Also I've seen this with new projects with default toolstrip item settings with NO code invol ...Show All

• Visual FoxPro VFP 9.0 SQL worthless under a non client server network?

  Hello everyone; I have posted this problem here and also on UT and no solution yet. I have a small network with a 2003 server, and XP pros. I am running vfp 9 select * from products where status = "S0000" takes apx 10 seconds when run over the network. When running this locally, it takes only a fraction of a second. The product table contains 100,000 records, and the result of the SQL command is just a few hundred records. I have checked sys(2023) and my temp files are on my c: drive. Does this mean that VFP has to run in a client-server environment in order for SQL commands to be performing reasonably ...Show All

• Software Development for Windows Vista More reading material

  I was wondering where could I get more papers to read about the WWF. There are few places that actually tell the interesting features, specialy codes and good examples of how WWF works. So if you have any link you might find interesting for someone, somewhat, new to WWF to read, I'd appreciate. Thanks.
