• Windows Forms Unable to cast COM object of type 'System.__ComObject' to class type...???

  I get the error below when I call many of the HTML... components, such as mshtml.HTMLAnchorElementClass or mshtml.HTMLDivElementClass. for example: foreach (mshtml.HTMLAnchorElementClass aAnch in aItems) When I do that the program dies immediately. and this error below is posted: Unable to cast COM object of type 'System.__ComObject' to class type 'mshtml.HTMLAnchorElementClass'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have any interop assembly registered will be wrapped in the __ComObject type. Instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. ...Show All

  Hello! I've got some trouble running my application on other computers. On my own it works fine (no errors while Debug or Build/Publish) but if I install it on other computers (with .NET Framework 2.0 installed on them, but no Visual Studio) it crashes after the splash screen and gives the following error: EventType : clr20r3 P1 : winlab.exe P2 : 1.0.0.0 P3 : 44ce7687 P4 : winlab P5 : 1.0.0.0 P6 : 44ce7687 P7 : d P8 : c6 P9 : system. invalidoperationexceptio n My application uses a 3rd party user control (I dont't have the source code), I think it might cause the crash, but I'm not quite sure.

• .NET Development Compression of SOAP message in web service

  I'm trying to get the SOAP messages from my web service compressed to reduce the data size when send to the client. Most examples I found are using external GZip libraries, but of course from .NET 2 it is possible to use GZipStream. This is what I have so far: [ AttributeUsage ( AttributeTargets .Method)] public class CompressionSoapExtensionAttribute : SoapExtensionAttribute { private int priority; public override Type ExtensionType { get { return typeof ( CompressionSoapExtension ); } } public override int Priority { get { return priority; } set { priority = value ; } } } public class CompressionSoapExtension : SoapExtension { Stream oldStream; Stream newStream; ...Show All

• Windows Forms Modal Dialog Box focus problems and Painting Problems

  I have written a Windows Forms application using C++ (.NET 2.0). I have encountered two problems I believe are related. The first occurs sometimes when I open a modal "dialog box", in the form of a MessageBox.Show, FileDialog or custom form using ShowDialog. The dialog box does not appear on top of my application, it is hidden and thus gives the illusion that my application has frozen (The Z-Order is not first). The second is that after displaying these dialog boxes (When they do show up on top), the controls under them do not repaint themselves, leaving "ghost" images of the dialog box that was just closed. I have found several threads on this forums posted by others who have encountered the same, or similar, problems, ...Show All

• Visual Studio Express Editions Saving Information

  Hello, I a making a program that will be opened once a day probably and some information will be imputed. How can I save the informaition to be used at a later date. I basically need to use something that is like a variable accept that the variable will be saved and after the program is closed and opened again it can be used. thanks Average Joe there are a good few topics about this. It depends how you want to save the information. You can save it into a database, a text file or perhaps an Xml file - the call is yours. It really depends what type of information is to be saved and who is going to be accessing it. When the program closes, simply save the data you want either when the us ...Show All

• Windows Search Technologies Does WDS update last access times of files that it scans and indexes?

  I'm beta testing a new utility (UltimateDefrag) that requires accurate last access time stamps in order to place the most frequently accessed files on the outer tracks of the hard drive for improved performance. I'm wondering if WDS updates the last access time stamps when it scans and indexes If so, is there a way to disable this without affecting the indexing and search capabilies of WDS Hello all, WDS should not be updating the last-accessed time of files that it indexes. There are, however, some other programs out there that do this (virus scanners are a prime example). Are you sure that the problem you are seeing is caused by WDS or could it be other applications Paul Nystrom - MSFT ...Show All
