Howdy, New program for the kiddies... This time, I'm creating a small graphics program where the alphabet letters appear, move, resize, recolor, sort, etc. I'm just getting started...I've got the first letter to move around the screen, and using the font size, color etc, I can get the "A" to move along in a path. I'm using: TextRenderer.DrawText(GraphicsFun, "A" , Me .Font, New Point(point1x, point1y), SystemColors.ControlText How is it that I can erase/remove the letter just before or after the new one appears I don't want to clear the screen/form/etc...just the last appearing letter. Thanks in advance...this site has answered what would appear to me to be hundreds of my questions for the two programs t ...Show All
Visual Studio 2008 (Pre-release) "Office 2007"-like window frame
Hey! I'm trying to do a gui looking like the new office 2007 beta 2 as an WPF-experiment. I would like a big circular button in the uppmost left corner of the screen. If you have seen the beta you know what I mean. I have made the button, but I just can't figure out how to get it to be in the titlebar. How can I do this I also would like to put a similar small shortcut-icon as they have in office aswell that is just to the right of the cicular button in the window title bar. I guess that if I solve my last question this shouldn'tbe so difficult. Any ideas Mr Olle Gustafsson Stockholm, Sweden Thanks for your answer! Is there any particular reason for using the AllowsTransparancy-property Shouldn't WindowStyle=None be enough Reaso ...Show All

SQL Server Getting AutoNumber values after INSERT
Simple question, I hope. How can I retrieve the AutoNumber generated by INSERTing a row using SqlCommand This would be the unique ID of the record and I need to perform other operations with it. Any help would be great. Thanks in advance I've have a brief look around, but I couldn't find any simple examples of this (it is a relatively simple system) but with little success. It is just a matter of doing something like; // Create the command string cmdStr = "INSERT [name] VALUES ('Test') INTO employees OUTPUT [employeeId]"; SqlCommand sqlCmd = new SqlCommand(cmdStr, connection); // Execute the command SqlDataReader result = sqlCmd.ExecuteReader(); After which the AutoNumber ...Show All

Internet Explorer Development Favicon in IE7
Hi My site uses a FAVICON, which works well in IE7. However, I've noticed that if you create a shortcut to a webpage on your XP desktop, the FAVICON is used as the desktop icon. My favicon.ico file has 2 res images of the file, 16x16 and 32x32. However, the desktop icon picks up the 16x16 version and uses that. Is there a way to make it use the 32x32 version. Or can I get windows to use a default icon. Thanks I have the same problem! Even worse. All the other icons of different webpages work on my Internet Explorer, only mine does not. I can copy and paste the line of other webpages in my html code and still no luck. My icon works well with Mozilla though. Does anyone know the reason ...Show All
Visual Studio Express Editions Counting pixels in a region
Yet another question.... I have a region that's made up of several shapes; some connected, some not. Is there an easy way to determine how many pixels that region is occupying I was hoping I'd find a solution in one of its methods but that doesn't seem to be the case. All of the shape information is stored in the region, you'd think it would be easy to count all the pixels in a given region. I will need to count/recount the number of pixels often so I'm hoping there is an easy/non-expensive (CPU/time wise) method for this. Because the region will contain non-connected shapes, and because the region is a solid color, would it be best to convert it to a 1-byte bitmap, then count that way Looking for any advice ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Help!! With Id3dxFragment linker
Question for the Black belts out there: I am writing a material editor application where i would like to let the user select different pre-written pixel and vertex fragments to work with to create a combined "effect". The interface finds all of the constants and displays the allowing the user to change things like material diffuse, specular power etc. I am familiar with how to use the fragment linker but I think i am missing something conceptually whenusing with with pixel fragments. In the dx samples they make it look like the fragment linker may be used to cascade outputs of fragments, i.e. linking a fragment for diffuse or ambient lighting followed by fragment for animation or not (as per the samples) How can i do this wit ...Show All

Visual Studio Tools for Office Outlook property page does not show correct
Hi all, i added a new property page to Outlook (developed with VSTO in C#). This page shows up, but it has a little bug. There is a small part which is not shown correct. I’ve added a picture which shows the problem. http://img.langalaxy.de/ppage.png What can I do, that the property page looks like "Outlook" property page Thanks Hi, you see the small bar at the bottom in standard control color. This belongs not to my user control. My control is actually bigger than the displayed part, but only the part with the "light color" is shown. For any reason my control is cut off at the bottom. thanks for helping ...Show All
Visual FoxPro Calling .NET from Foxpro
Hi, I have a .NET dll that I need to call repeatedly from within a Foxpro app. In effect, I'd like to instantiate a class in a .NET assembly and call its methods just like any other Foxpro object. I've never done this in Foxpro before. Is there someplace where MS has some relevent documentation that can shorten my learning curve Thanks Here's a good article on COM Interop by Rick Strahl [MVP].

Silverlight (formerly WPF/E) Image formats?
What image formats are supported Is there a reason GIF is not supported Again I've run into a situation where nothing would render and yet no error handler was called. This time apparently it's because there was an <Image> element with a "Source" attribute referring to a GIF file. It's very frustrating to try to work with WPF/E when it doesn't provide feedback for cases it knows it can't handle. In this case I rather doubt it's an XML validation error. So why isn't the error handler being called I can understand if the WPF/E implementation at this stage doesn't support some image formats. And I can understand that the documentation isn't complete. But I'm surprised that GIF files appear not to be supported, given ...Show All
