• Visual C++ Candidate function(s) not accessible strange case

• Visual Studio Tools for Office ServerDocument.AddCustomization() starts new Word Instance

  Hi, I use VSTO ServerDocument.AddCustomization() method to dynamically customize Word .doc file. However, if I try to customize a fresh (new) Word .DOT file, a new instance of Word is started even if one already exists. This is causing so much pain. Also, this behavior is NOT repeated if the .dot file is already customized and I re-add the customization after removing it first. Here is the code: private void button1_Click(object sender, EventArgs e) { string fileName = @"C:\Documents and Settings\My Documents\Template1.dot"; this.StartWordApp(); this.DoThis(); MessageBox.Show("Annonymous Template Created and cl ...Show All

• Visual C# Are strings any easier in the new C#?

  I stopped using C# about a year ago. I hated the complexity of using strings. Gone were the days of MyString = "Hello"; I had to now make an object. String manipulation, which was once easy using MID, RTRIM, REPLACE, etc., now is tedious. Anyway, I was wondering if the newest version of C# has made it any easier Um, you couldnt do - string s = "Hello"; what was so hard about - string s1 = s.Trim() string s1 = s.Substring(1,2); Its no different than in VB.Net. Unless you use the non CLR compilant VisualBasic assemblies; no different except that, in vb, dec ...Show All

• .NET Development how to concatenate data from two Byte arrays into one Byte array?

  Hello!   Does the .NET framework provide an easy way of merging two  Byte arrays into one boc First a low level one: byte [] one = { 1, 2, 3 }; byte [] two = { 6, 8, 9 }; int length = one.Length + two.Length; byte [] sum = new byte [length]; one.CopyTo(sum,0); two.CopyTo(sum,one.Length); Then a bit better, use the generics List<T> collection byte [] one = { 1, 2, 3 }; byte [] two = { 6, 8, 9 }; List < byte > list1 = new List < byte >(one); List < byte > list2 = new List < byte >(two); list1.AddRange(list2); ...Show All

• Software Development for Windows Vista Access violation errors

  Hi.   I'm trying to make a DirectShow app in C++. I'm using Visual Studio 2005 Express, and I don't want to use .NET for various uninteresting reasons. I can get programmes to compile fine, but every time I try to run them it comes up with access violation errors. I feel sure there's something fairly simple and probably fairly obvious I'm doing wrong, but I really don't know where to start figuring out what that thing is. In this example, the violation occurs when I try to call pGrab->SetOneShot( true );. The really strange thing is that calling pGrab->SetOneShot( false ); works perfectly, or appears to (or rather, ...Show All

• Visual Studio Team System Baseless merge ?

  I've been told a couple of times to workaround problems with branching via a Baseless Merge.  Now I'm pretty sure I can guess what this does based on the name, but I can't find any way to accomplish this through the VS2005 UI. I've read all the docs I can find and I've searched google and all I've come up with is the command line option to do "h.exe merge /baseless" from MSDN and the reference from Buck's blog. The description in the docs being : /baseless - "Performs a merge in the absence of a basis version" Am I missing something in the UI or is it just not in there yet Excellent.

• Visual C# Problem with LRC-Checksum

• Visual Studio Express Editions A lot of code on one form when using tab folders. Any solutions?

  Hi, I am using VB.NET 2005. I have a fairly large program and have broken it up into tab folders. I would like each tab to have a seprate form in order to isolate the code associated with each tab. I notice that the way VB.NET uses tabs, all of the code is on one form which makes finding code segments messy. Is there a way to fix this, or do I have to live with it. I am using modules extensively to reduce the amount of code on the form. Any suggestions would be helpful,. Thanks, quicksun Thanks Paul. Between your suggestion and the others, I think I have a roadmap to follow. Thanks for the help. qu ...Show All
