• Visual Studio 2008 (Pre-release) TextBox, IsReadOnly, Focus

  When I set the IsReadOnly="True" then this text box no longer gets focus. If I want a readonly text box but with focus function as always how can I achieve that It actually get the focus but do not show the caret. Itzik Bill Henning wrote: I was just about to post on this subject and found this thread. I'm running into a scenario where I'd like a TextBox to be read-only but I do want the caret to show and be allowed to move around. End users may wish to select a portion of the text and copy it to the clipboard even though it is read-only and right now that seems impossible other than via mouse use. Any chance this will be fixed in the future to work more lik ...Show All

• Visual Studio Tools for Office Question regarding creating, saving and emailing EXCEL document

  Hi, I am using C# and VSTO to populate an EXCEL document from a database. I then want to email this EXCEL document as an attachment to a specified number of users. Everything works except when I try to open the attachement. I receive the following error "The file could not be accessed. Try one of the following: Make sure the specified folder exists, Make sure the folder that contains the file is not read-only, Make sure the file name does not contain any of the following characters.......". I tried sending a file, .xls and .txt, that already exists and the attachment opens up correctly. I think VSTO is not properly closing excel before emailing it. Does anyone have any ideas on how to fix this Below is the code: ...Show All

• Visual Studio 2008 (Pre-release) Custom transport - protocol transport

  Hi, I'm trying to understand the building blocks that go into a custom transport. For my specific scenario I need to build a custom TCP transport to support different message framing scenarios. However, I was wondering where one would implement high level protocol logic. For example, let's say you have simple text messages like: LOGON| REQUESTSOMETHING| HEARTBEAT| etc. Now, for example the client sends REQUESTSOMETHING| before a LOGON| thus you need to reject the message and every x seconds you want to send a HEARTBEAT| .. etc... where would this session logic be implemented Thanks, Tom Thanks, I will have a look at those. Another question I have right now has to do with the Message class. Is my understan ...Show All

• Windows Forms how to know that a user control is in design mode

  I have a user control which normally displays a large amount of data from an application. This is similar to an excel chart. When I drop this control onto a form, I want to put some dummy data in, so that properties can be previewed. I can't see how (within the control code) to determine that the control is in design mode. How can this be determined Trev Use the DesignMode property on the control (it's actually defined on Component, which Control inherits from). Sometimes that isn't always accurate, so it's sometimes a good idea to use it together with a check against System.ComponentModel.LicenseManager.UsageMode == System.ComponentModel.LicenseUsageMode.Designtime. ...Show All

• Visual Studio Express Editions Embedded forms

  How can I embed a form inside another Both these forms should be synced, ie: when parent is resized, child is exactly resized. When parent is dragged, child is dragged Thanks !   Brendan Grant wrote: In order to acomplish the second bit you may want to think about making your parent form an MDI container . If you did that, the first option would be even easier as you would need only set the Anchor property of your child forms to the sides of the parent that you want it to resize along with. Does this work for you Thanks ! Assuming I am not creating forms on the fly... I have frmParent & frmChild. frmChild will always be on top but may not always be shown. Do ...Show All

• Visual Basic tabcontrol used in Visual Studio

  Is there any way to have a tabcontrol that looks similar to the one used in the Visual Studio IDE The existing tabcontrol provided by .NET 2.0 doesn't look nice. I wish I could have a tabcontrol similar to the one used in the Visual Studio IDE :-). I put out a rendered version of the tabcontrol today.

• Windows Live Developer Forums Newbie. I want to enhance the image quality.

  Hello, this is very basic, but I need to know the power and flexibility of this tool. I need to see in a superior level of detail, in 3D view, a city with a few mounts... ( I don't need buildings, just the terrain ) But everything that is at a certain distance from the camera looses quality (geometric detail level and image quality). I know this is done in order to increase render speed, to save memory and bandwidth... but I need more quality, and I'm ready to pay the cost. Is there a workaround to increase the quality, someone knows a website, parameter, anything that might help me please I need it, even if it takes quite a long time to display one single image. I need excellent quality. Thanks in advance! Albert G ...Show All

  I'm running SQL Server on a remote machine. I can connect to it with no problem using Sql Server Enterprise Manager or Query Analyzer. I recently had to reinstall my operating system and reinstall Visual Studio .NET 2003. Before doing this I was able to connect to the database from within ASP.NET using the same EXACT connection string I'm using now. Since I reinstalled the O/S and .NET, none of my .NET applications that connect to Sql Server can connect. I'm not having any problems with connections to MySQL at all.

• Audio and Video Development uncompressed YUV to EVR

  Hi, I am writing a simple YUV media source to take in .yuv bytestreams and send it to the EVR. I have modified the MFT_Grayscale to act as a dummy transform to copy the yuv samples to the EVR. I am also using the playbackFX sample for the player. I'm having a problem with the player just showing a black screen, as if no samples are being sent to the EVR. I have verified that the samples are being processed in the dummy transform with the correct image size and attributes for my given yuv sample. I have tried other yuv samples and all just display a black screen, but the samples are being processed for sure. Is there any way to debug this to see if the samples are being sent to the EVR Or does anyone have any clues why this is happeni ...Show All
