• Visual Studio Express Editions HotKeys :(

  I've been googleing for a week and I can't find any tutorials for 2005. Can anyone help me Oh the qestion is about how to use hotkeys. http://www.google.com.au/search hl=en&q=hot+key+VB.NET&meta = Seeing as the articles are using dllimport, they are calling Win32 API functions, and it doesn't matter if the article is 2003/2005 ( actually, it should not matter anyhow ). ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Degraded performance when debugging MDX1.1 applications in VS2005 compared to VS2003

  Hello, I've noticed that when I'm debugging MDX1.1 applications in VS2005, they achieve a significantly lower framerate than when debugging them in VS2003. The performance decrease differs per application and seems to be somehow linked to the use of HLSL effects, as applications that use the Fixed Function Pipeline do not suffer this decrease. This morning I witnessed an extreme case of this problem with a little game that renders multiple meshes using HLSL effects. It achieved a lowly 60fps when I ran it in debug from VS2005, whereas it achieves a 550fps framerate when I just run the debug exe from Windows Explorer ...Show All

• Visual Studio 2008 (Pre-release) can't generate proxy classes for WCF SDK samples with svcutil

  Hi, I tried to generate a proxy class for GettingStarted service yesterday with FEB CTP svcutil.exe on FEB CTP Vista. But svcutil failed after reporting a few warning messages. The GettingStarted Service was running OK and I didn't modify it in any way. Does anyone know what is it I've read some known issues concerning FEB CTP svcutil. They do not seem to be relevant to the case. Can you send the error message/warnings etc Thanks! Scott ...Show All

• SQL Server Single Database w/ Multiple Subscribers Merge

  I am attempting to have a single database with multiple subscribers. I am running into limitation when attempting to use a single database to perform a merge replication on behalf of a user (hostname) where the user changes for each call. I am using Microsoft SQL Server  2000 - 8.00.2039. The reason for doing this is to support a device that does not support SQL Server CE and providing a mechanism for merging data from the device into a database (subscriber) and then performing a merge with the publisher for that user. It is understood that the upload will upload any changes that occur on the subscribing database, regardless o ...Show All

• Visual Studio Team System BUG: Invalid handle on concurrent checkout/checkin

  If I am checking out the a project file. My colleque checks out the same project file (concurrent checkout) Then he checks in the project file. Now, when I am trying to check it in I get an error box saying "Invalid Handle" Restart, Reconnect to TFS doesnt help. However, If I do a "Get lastest version" then it triggers a merge request, after I done the merge, the checkin works fine. Regards Fredrik Melin After further review on our merge issue it appeared that it had something to do with line endings.  The merge tool showed half of the code updated which none of the code had been touched.  When we put in a diff ...Show All

• Visual C# Working with images : help needed!

  Hello, guys. Let's say that I load a image in a picture box. What I want, is to slice the image into sqares [eg: 10x10]. After the image has been sliced I want to replace each sqare with another image from the current directory...I hope that you get my idea!

• Visual C++ how to get errors for nonstandard ISO c++?

  As I understand it, "for each" (as opposed to for_each() from STL) is not allowed in standard ISO C++, it's part of the new C++/CLI standard instead. So if I take the program below, it doesn't compile in Cormeau's compiler. However, it compiles in VC2005 even if I use /Za and do not use /clr. My question is, how can I prevent the compiler allowing new constructs like this My friend's compiler doesn't compile them!

• Visual C++ differences in symbols between 2003 and 2005 msvcrt.libs

  Why doesn't the new msvcrt.lib contain all the methods that the past msvcrt.lib has, in specific the __iob function I have always used the multithreaded dll in past projects and versions because Microsoft has always recommended it. Now I have older libraries that were built according to their advice using the msvcrt.lib and that rely on the presense of the __iob function and the function is not in the new msvcrt.lib. I don't know how to proceed. Can someone provide me with steps I need to take to get around this As the two underscores show __iob is an internal variable of the CRT. You have to recompile ...Show All

  TSIA... Is there a method, or some kind of quick test I can perform against a string to see if it contains anything other than ascii characters Thanks alot, Scott ASCII characters are limited to the lowest 128 Unicode characters, from U+0000 to U+007F. so you can write a helper method to check the every single input character to verify whether or not it is in the ASCII code range.

• Windows Forms Flicker when changing BackColor of Node in TreeView Control

  Hi all, I have a treeview in my winform in which I need to change tree node's BackColor/ForeColor in a treeview control in running time. But I found the heavy flickering when I change them. The treeview seems to in-validate whole control even changing only one node's BackColor. I tried to use BeingUpdate and DoubleBuffer but still don't have solution to it. I don't post my code here, a good example of demonstrating this problem could be reached in the below link: http://www.codeproject.com/cs/miscctrl/MWTreeViewv2010.asp This example is a multi-select treeview control , after I browse its code, I found it realizes the multi-selec ...Show All

• Visual Studio 2008 (Pre-release) Element Operators: First vs. Single

  After perusing the Standard Query Operators doc (available here ), I'm a bit curious about the differences between - [1.13.1] T First(IEnumerable<T> src, Func<T, bool> predicate) and - [1.13.5] T Single(IEnumerable<T> src, Func<T, bool> predicate). At first glance, they appear to be synonymous. Are they the same What motivated the decision to provide two methods which perform the same action Also, as an aside, why is Func<T, bool> preferred over the existing Predicate<T> for all of the query operators Predicate<T> is an established delegate and seems a bit more descriptive, but I can see the argumen ...Show All

• Windows Forms Determine When an Edit Begins

  Hi, I'm trying to determine when an edit begins on data bound controls on a form so that I can enable only the 'Save' and 'Undo' buttons on my BindingNavigator. I'm using VB .Net 2005, I'm accessing data via an OleDBDataAdapter, which populates a DataSet.DataTable. I have a BindingSource connected to the DataTable, and the form fields bound to the BindingSource. Lastly, a BindingNavigator is tied to the BindingSource. Rather than try and trap TextChanged events for each bound control, I'd like to trap a single event at the Form, BindingSource, or DataTable level, but I can't seem to find events that fire as soon as the edit begins. ...Show All
