• Community Chat Using Vista?

  Good idea Joe! Okay, I'll go first.  I'm using Vista RC1 full time now.  The computer seems quieter--doesn't take so many trips to the hard disk for VM paging.  I find going back to XP an unpleasantry, so I think Microsoft is succeeding here. Glass is nice.  I think the performance is what I expected it to be on an Intel Advanced Graphics card (Dell Dimension 9100).  Office 2007 is also pleasant to use, but they stil have some cleanup work to do on their UI. Who else is using Vista   Brian its actually also stated and recommended by Microsoft to NOT install beta/prebeta/RC products over your existing configuration - it's as simple as that I remember about 2 yea ...Show All

• Windows Forms Datagridview combo unique values problem

  hi, i have a combobox in a datagridview control. this combobox retrieves a list of values from another table. Durnig an insert of a new record, i wnat the user to select a value from this combobox.

• Visual C++ How to know the Number of Bytes allocated to a Pointer.

  Hi Friends..... Is there any function to know the number of bytes allocated to a pointer. Ex: foo() { int *intList = NULL; intLIst = (int *)malloc(sizeof(int) * 10); freeList(intList); } freeList(int *intList) { /*How to collect the total number of bytes allocated for intList*/ free(intList); } Thanks.... I case of Visual Studio 2005 and memory blocks allocated with malloc , calloc or realloc functions (but probably not by new ), for debug purpose I think you can try _msize function [ http://msdn2.microsoft.com/en-us/library/z2s077bc(VS.80).aspx ].   I hope this helps.   ...Show All

• Visual C# serialization demystifyied :)

  Hello, can you advise me information about serialization in .NET Framework 2.0 on the web I imagine something more compact than actual MSDN docs are, focused on this topic. In MSDN I didn't found some info, for example: - why ISerializable implementation is not invoked using XmlSerializer and how to customize serialization of specific properties then - why ISerializable methods and any xml attributes do not seem to be required at all, although they're told to be required. - why, when serializing a hierarchy of objects, the contained types (extra types) do not output full type name and just the ending identifier, and how to solve that..(!!) I appreciate tips where to learn about, also if you can advise to this concrete pro ...Show All

• Visual Studio 2008 (Pre-release) GroupBox "off-by-one" Bug?

  I noticed that when I started nesting GroupBoxes inside Grids, sometimes the bottom-edge and/or the right-edge of the groupbox wouldn't be drawn, it looks like they are beeing clipped because they end up just outside the area for the groupbox. (this doesn't happen if the groupbox isn't inside a grid, and also it seems more prone to happen in different quadrants in the grid).Try the following xaml, and adjust the size of the window: < Window x:Class = " WPF .Window1 " xmlns = " http://schemas.microsoft.com/winfx/2006/xaml/presentation " xmlns:x = " http://schemas.microsoft.com/winfx/2006/xaml " Title = " WPF " Height = " 330 " Width = " 507 " > ...Show All

• .NET Development Now...Absolute path from mapped drive

  In a previous post I asked about getting the absolute path from a drive created by the SUBST command. Now I'm looking to get the absolute path from a drive created by the Tools->Map Network Drive gui (if that drive is mapped to a local folder). I can already use WNetGetConnection to get the UNC of a mapped drive on a network share; but can't quite figure out how to convert that to a local path when it's local. Any help is greatly appreciated. rr12 ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Disabling mipmap and mipmap question.

  I wish that my shader will not use mipmap, however, I get a runtime error when trying to set MipFilter to anything but Linear. The error: "Index is required for state MIPFILTER" I tried to set sampler state parameters, but it didnt help. I will add the code for creating the texture and the shader code. My additional question is, why the hardware does not calculate the mipmap levels textures with anisotropic Also, what is the advantage of mipmapping is it only for better details or also performance Thanks for any help. p.s., is there a better way to present source code in this forum HR(D3DXCreateTextureFromFile(gd3dDevice, "crate.jpg" , &mCrateTex)); //======================================================== ...Show All

• Visual Basic replacement for quick-console

  After some time thinking I was crazy because I couldn't show a quick console I did some searching of posts to find out that quick console has bee removed in 2005 :(. It seems that a few people have asked what to do in its absence but have received no answer. I will see if I have better luck, because I really need its functionality. Without quick-console, what is the easiest way to quickly display text for debugging purposes without interrupting program flow I have tried using system.diagnostics.debugger, but have had no success and the docs aren't so great. SteveJ if you haven't, you could do: System.Diagnostics.Debug.WriteLine( ValueHere ) and it will display it in the output window when you are running the applicati ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA/Xbox 360 memory management heads-up...

  I was just browsing through some docs on the 360's heap manager, and it turns out it is a compacting mark and sweep collector rather than the generational model used on the desktop... So... what's the deal regarding: Large block allocation (will it have a large object heap like the desktop version ) GC pauses times (do all threads halt during GC) Rico Mariani recommends a heap size equivalent to the Gen 0 size on the desktop, i.e. ~cache size. That seems way too small unless we are dumping lots of game data into unmanaged memory! Andy. We actually do allow C# unsafe code blocks on Xbox, including arbitrary pointer arithmetic. You just don't have any way to P/Invoke into native code from the managed san ...Show All

• .NET Development Run a process with admin rights

  hi everybody. I have a problem to launch a process with admin rights. The application has to work under Windows Vista (I developp under the last CTP). The account running my application is an admin account and the process I need to launch is "bcdedit.exe". When I run my application, bcdedit (launched by my app) says that it doesn't have enough rights to work correctly. If I run my application by doing right button on it > run as administrator..., the process works correctly but it's not a solution for me. I would like to know if I could run a process specifing rights admin or a windows identity with admin rights. thanks per advance thanks...but no because it asks me the password of the accoun ...Show All

• Community Chat WebBased cookieLike application

  I wonder if anyone out there is working on a web based application to maintain userids and passwords. What I mean is that I'm pretty much annoyed with having to remember passwords and userids to the gabazillions of websites I'm registered on. Cookies are fine till you are working on your own PC but how about some freedom of movement Just log into the webbased cookieLike (I even gave it a name) application, have it do the sweatwork of redirecting to your registered website of choice and automatically logging you in. No more remembering passwords. This is my first post so I'm not really sure if this qualifies as a "Hot Technology" post but oh well :). Off course some bigger compani ...Show All

• Software Development for Windows Vista UAC Prompt, interrupt or background

  I notice that in more recent builds of Vista, launching our app will no longer interrupt the user with a UAC elevation prompt. Instead, a task bar item will flash. Clicking on that taskbar item will then bring up the prompt. I think this is MS' way of making UAC prompts for "non critical" apps less intrusive. My question is, is there a way to force the UAC prompt to interrupt the user Is this a setting in the app's manifest file I'm not having any luck locating an answer. Thanks. ...Show All
