• Visual C++ very strange problem with std::string, std::stringstream and bad_alloc exception

  Hi, I am developing an application which looks like this: App A uses DLL B which uses DLL C. B And C are non-MFC DLLs. A is an MFC console-app. B exports a class class1. Class1 contains a single member of Class2. Now the following code leads to bad_alloc exceptions in std::string: in A lets have Class1 *pmyclass1 = new Class1; Class1->foo(); void Class1::foo() { m_class2.bar(); } void Class2:bar() { std::string foo; foo = std::string("This string has more than 15 characters and will lead to heap corruption"); } When the last line of bar is executed bad_alloc is raised. How can that be What's wrong here Additionally bad_alloc will also be raised if you dec ...Show All

• SQL Server Totals on last page only - How?

  Just started (today) using RS2005. Me and my Brian Larson MS RS2005 book. Can't figure out how to get my Grand totals to ONLY print on the last page of my report. They are calculating correctly, but printing on every page. I guess I wouldn't mind if the totals were page specific, but it's not even doing that... Thanks!!

• Game Technologies: DirectX, XNA, XACT, etc. Bug in BoundingFrustum.Contains()?

  If i write the following code: BoundingFrustum f = new BoundingFrustum(new Matrix(1, 2, 3, 4, 5, 6, 7, 8, 9, 8, 7, 6, 5, 4, 3, 2)); Vector3 vector = new Vector3(1,1,1); BoundingBox box = new BoundingBox(vector, vector); ContainmenType t; t = f.Contains(vector); Console.WriteLine(t); t = f.Contains(box); Console.WriteLine(t); I'd expect both to give the same answer. Either both are contained or both are disjoint. However the Frustum contains the point but the box is disjoint. What's going on As to your zeroed bounding volume : all operations with a volume of zero size are discarded by compiler as having no sense at all.

• Smart Device Development SHFullScreen too often returns "true" - How to check state of taskbar etc.

  SHFullScreen(m_hWnd, SHFS_SHOWTASKBAR | SHFS_SHOWSIPBUTTON); To my mind, this call should return FALSE on a pocketphone because the SIP button isn't supported, right However, it returns TRUE. What's the proper way to check to see if there is actually a taskbar, sip button, start button, etc. currently displayed on screen Also, it would be nice to have a call that returns the actual height of the taskbar in case that ever changes (or will it never change ). I suppose we can rely on the following: a windows CE application always launches with the taskbar displayed at the top of the screen a windows CE taskbar is always 26 pixels the location of an application frame window always starts at (0, 26) The third assertio ...Show All

• SQL Server What is necessary to create SDF-Files on desktop legally?

  I want to write a PC application that prepares a SQL Server Mobile Files (.SDF) and sends it to a PocketPC. I get this error message: "SQL Mobile usage is restricted on this platform. To use SQL Mobile, you must install SQL Server 2005, Visual Studio 2005, or the Tablet PC SKU" If I install "SQL Server 2005 Express" the error message disappears and everything works fine. Question: Is it allowed to create SDF-Files if "SQL Server 2005 Express" is installed or is it necessary that my customers buy "SQL Server 2005" It's faster, easer to use, requires little coding on your part and works over HTTP so it can go through firewalls and your SQL Server is not exposed. But, sure, you can use SQL Cli ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Losing Background Surface

  Hiya, I'm working on a simple 2d shooter game in VS 2003 using managed DX. Problem: my backgrounds (LPDIRECT3DSURFACE9) start disappearing after x levels Computer 1 has a Radeon Mobility 7500 that has 32 meg of VRAM and starts losing backgrounds after 7 levels. Computer 2 has an integrated graphics card with 64 meg of VRAM and starts losing backgrounds after 11 levels.

• Visual Basic using tabcontrol's tab pages to select a specific user control from a panel collection

  If you can catch my drift in the code below, I'm trying to select tabcontrol tabs on a tabcontrol on the right side of a split container. (There is a separate tabcontrol on the left, which has tabs, whose selection will spawn a different set of tabs on the right tab control. I am having a difficult time selecting a tab on the right, and having it display the correct user control. I am using only one panel with a collection of controls, rather than a tab page for each control.( For some reason that proved to costly performance wise.)  Does anyone understand what I am 'trying' to do Thanks -greg Private Sub TabControlRight_SelectedIndexChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabControlRight.SelectedIn ...Show All
