• Visual Basic VB.NET 2003: Object must implement IConvertible Error...

  The Following post explains in detail the error I am receiveing and provides the modified code I have implemented based on help tools. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=828435&SiteID=1 I think you'll need a serialized string of byte data instead of an array.  Basicly take the value of each byte and create a concatonated string... Byte(0) = 255 Byte(1) = 143 Byte(2) = 45 Byte(3) = 9 Byte(4) = 214 Serialized into:  255143045009214 Not sure what the order should be or if you should use decimal, hex, or binary values, but the datatype of the SQL field is expecting a string of data... ...Show All

• Internet Explorer Development Where can I store images that my extension injects into the DOM on Windows Vista?

  I have a toolbar that does some direct DOM manipulation, sort of the way the IE Developer Toolbar does. Part of this DOM injection are some images that we use. Previously, we were programmatically inserting our images into the Temporary Internet Files folder, and when we created our DOM objects that needed these images the URLs pointed to the images in that folder. The problem is, that on Windows Vista it now seems that Temporary Internet Files is now considered a system folder, and I have lost the ability to write to it. At this point, I think I have a few options but am unsure as to how to implement any of them: 1. Store the files in an accessible temporary location (using a different Special Folder, maybe ). I don't know which one, i ...Show All

• SQL Server sp_send_dbmail HTML body with stored procedure results in body?

  Hi all, I'm playing around setting up a sp_send_dbmail report to send me deadlocking information. I've written a stored procedure ( utilities.dbo.GetDatabaseDeadlockingDetails ) and I would like to recevied the results in an HTML body. I can easily add the results as a seperate file, but it is far easier to use inside the email. Since the formatting isn't particularly nice as text, I wanted to get it as HTML. Now the sample in BOL: DECLARE @tableHTML NVARCHAR(MAX) ; SET @tableHTML = N'<H1>Work Order Report</H1>' + N'<table border="1">' + N'<tr><th>Work Order ID</th><th>Product ID</th>' + N'<th>Name</th><th>Order Qty</th><th>Due Date</ ...Show All

• SQL Server Error 1203

  I am running a script on a schedule and I get this error quite often: Unspecified error occurred on SQL Server. Connection may have been terminated by the server.

• Visual Studio Team System MICROSOFT - Please Clarify

  For me all this is hopelessly confusing. Can anyone from Microsoft tell me if I will be able to install CTP7 with my current copy of Visual Studio Team Edition for Software Developers I don't want to uninstall CTP6 and then be told I don't have the correct version of VS to install CTP7. Thanks - Amos. Hi Amos, No. If you have no other version of VSTE, then DataDude (RTM) will install as a standalone product. AKAIK - If you DO have VSTE (for example Developer) THEN DataDude will (as it does in VSTS) extend the installed Version to include the DataDude features. This is why CTP7 will not install alone (RTM will). CTP7 is only the extensions required on top of VSTS but does not include ex ...Show All

• Visual Studio Tools for Office Prevent Outlook from embedding attached image

  I'm using Outlook 2003 and C# and I'm trying to create a MailItem using Microsoft.Office.Interop.Outlook.Application It is working so far, but there is a small problem. I create a new message and set the the BodyFormat to olFormatHTML. Then I attach an image "test.png" to the mail. In the HTMLBody I use this image as a source: <img border="0" align="middle" src="test.png" /> After executing Display(false) on the created MailItem object I see this message, but without the image attachment - it is automatically converted to an embedded image with the cid:-link as image source in html code. Is it possible to use attached images as image sources in html-body, but also to keep them as at ...Show All

• Software Development for Windows Vista Using AVIStreamWrite seems to be corrupting AVI headers on Vista (RC2 build5744)

  I am using the Video for Windows (VFW) API to create AVI files. My code works fine on XP Pro SP2 and Windows 2000. However, the same code running on Vista creates the AVI files with bad headers. The corruption begins after the video and audio stream format headers starting at the JUNK chunk. Example: //Stream header info comes before this Low rate size 00000294 (660) 00000000000000D4 JUNK 00000000 00000000000000DC LIST 0002200E movi 00000000000000E8 00000000 00000000000000F0 00000000 00000000000000F8 00000000 Notice the JUNK chunk has an invalid size of 00000000. And the 'movi' tag falls within the junk chunks. This throws off the indexes. I found that this "junk" gets wri ...Show All

  I would like to add role information to a customised work item. When a user is chosen from a dropdown, I would like the role dropdown to default to the chosen user's role.

• Architecture Which protocol?

  I'm writing a solution for communication with a (.net) server. Now I'm thinking about a protocol I should use(Remoting, WebService, Sockets, ...). There are some things to consider: There may be many clients connecting to the server with that app (100000 ) I want this app doesn't have any problems with routers (firewall, NAT) Later, there will be a C++ client (not managed) I'm tending to webservices because of (2,3) but don't know if there will be performance issues... What would you do Konstantin Hi Konstantin, Remoting can work well over HTTP, so firewall issues will not help you decide here. I dont think that there is a straightforward way to directly call .NET remoting services from unmanaged C++ client ...Show All

• Visual Basic How to cast to the parametrized type?

  In my application, I have got a subroutine, which should retrieve the active window, check its type and return it in case of success. I wrote it with the generics syntax: Private Function ActiveWindow( Of T)() As T Dim f As Form = Me .ActiveMdiChild If TypeOf f Is T Then Return DirectCast (f, T) Else Return Nothing End If End Function But compiler says that System.Windows.Forms.Form cannot be converted to the type T. As you can see from this code, f can always be converted to the type T. I have found out really weird thing about that. If we modify the code in the following way, everything works: Private Function ActiveWindow( Of T)() As T Dim f As Form = Me ...Show All
