• Visual C++ Stack corrupt after managed callback (w/ parameter) from unmanaged

  I have a callback function that calls from unmanaged to managed code. Using code derived from the MSND article “How to: Marshal Callbacks and Delegates Using C++ Interop”, it works fine. When I change the callback function and the delegate to pass a parameter I get a corrupted stack. Could anyone offer a suggestion of why this is happening Any help a greatly appreciated. Here is a short sample program that shows the problem with the output. // CallbackTest.cpp : main project file. // compile with: /clr #include "stdafx.h" #include <iostream> using namespace System; using namespace System:: ...Show All

• Windows Forms passing variables to form

  I made my textboxes on form1 public. I was able to access them through my form2, after I made a statement like form1 form2 = new form1();   Problem is, the text boxes are all empty on form2.

Awesome.. thanks.. that worked.. I have no idea why I never tried that. So all I gotta do is define my variables globally. I thought I tried that.. guess not cause I tried a few tests and it works great. Jeez this language makes it awkward to p ...Show All

• Visual C# Flushing datatable to an Excel file usin InterOp

  Hi, I'm working on an C# winforms application. I am binding a datatable to a datagrid. The user can do update, insert and delete operations on this grid. I wanted to know how do I flush this datagrid to an excel file using Interop. And, I wanted to know how to delete an Active Worksheet from an excel file using Interop. Thanks in advance, livehed Interop is probably not your best option. Instead, try opening the Excel file as a datasource through an OleDbConnection. See http://support.microsoft.com/default.aspx scid=kb;EN-US;306572 for examples. There are various issues to deal with in this approach, but ...Show All
