• Visual FoxPro combo box inside a cell in grid

  hello, i wonder how to integrate the combo box in a cell of a grid. i saw this in one of the existing apps. i want the user to be able to select a record in that combo box and changes the record on the other cells in the grid. can anybody here to please guide me on how to do it. thank you jason what you can do is drag a combobox to a hidden part of the form. and everytime the user would click on a cell in the grid, you would change the coordinates of the combobox and make it visible. Then after the user clicks the combobox, you would transfer the text from the combobox to the grid and thereon make it invisible. ...Show All

• Visual C++ Is it possible to consume a VB.Net .dll from C (unmanaged not c++)

  I have a VB.Net dll that contains functionality I need to access from a C program. As GetProcAddress won't get me where I need to go (right ) and I cannot create an instance of anything (C not C++) is there a route possible to loading this library I assume that it's not an option to recompile the C code as C++ That would be the easiest route (use the /Tp option). Failing that, you would need an intermediate layer of C++ code compiled with /clr that makes your calls into the VB code. This would contain a #using statement to access the VB assembly/dll and expose global functions visible to the C code. These functions would be declared as extern "C" and could be exported using __declspec(dllexpor ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What units are the x, y, z components of a Vector3 with respect to screen space?

  Hi, I've just got hold of the XNA Beta and have a really basic question really. The following vertex VertexPositionColor [] vpc = new VertexPositionColor [1]; Vector3 v1 = new Vector3 (0.0f, 0.0f, 0.0f); is drawn from what I can see directly in the middle of the game window. I tried varying the x and y components of the Vector3 and found that it does not like values above 1.0. I can move it by incrementing the x or y components by 0.1f. And so my question really is how do the units I provide to vertex Vector3s relate to screen space I am used to systems that a) start from the top-left of the window and b) where if you say Vector3(10, 20, 0) would draw the vertex at 10 pixels across, 20 pixels down.

• .NET Development Dynamic Assembly Binding... how?

  I'm confused how dynamic binding is even possible. If I have 2 DLL's, named Parent.DLL and Child.DLL and child needs to have a reference to parent, well, if I drop all the hard coded references from child to parent and instead throw in a line of code that dynamically binds, isn't my project going to throw a fit when I try to build the Child.DLL and it no longer contains the hardcoded reference to the Parent.DLL It will only throw a fit if your Child.dll contains code that attempts to statically bind to types defined in Parent.dll. But if you've removed all statically bound code, that won't be an issue. Of couse it's not enough just to add a new line of code... Any time you do anything with something from Parent.dll, you'll ...Show All

• .NET Development Xlink - How to use xlink in every browser ?

I used Xlink for my links, the simple version (http://www.w3.org/TR/xlink/). The links function correctly under Firefox 1.5, but impossible to make them function with Internet Explorer 6 or Opera 9.
