• Windows Forms Draw line in a user control...

  Hi, I am trying to draw a line between two point in a usercontrol or panel, Here is the way I want the program to run: (1) user click some point in the control, and will be marked with a black rectangle.

• Visual Basic Generating text around an arc in an image file

  I am new to this, so please, if I am in the wrong place, tell me the proper place for this question. I am trying to generate a graphic programmatically with dynamic text. The graphic should display text written around a circle, as if on an arc, and the text itself should be angled so that if you underlined each letter, the underline is perpendicular to the center of the circle. I had code that did this in VB6, using a LOGFONT and it works really well. However, the VB6 code printed directly to a printer. I am upgrading the code to VB.NET 2005, and because of outside constraints, I need to output directly to an image file which will be printed later. I had problems using LOGFONT, namely that it did not "tilt" any of the ch ...Show All

• Visual Basic How to set the install path for application

  I noticed that my app doesn't install to the Program Files directory as VB6 does it. Instead, the wizard creates a jumbled multi level directory and sticks your app in there. How can we change that Thanks. I'm trying to get the Setup included in the project - somehow, somewhere. VS has no organization skills whatsoever. Programs always go in the Program Files folder. Creating a random (who wrote this stuff anyway ) directory each time, is a mess! You can install the files multiple times and don't even know it. Under VB, it would have told you folder/files already exists, do you want to overwrite Instead, you have a bunch of jumbled folder names each time you run setup. Even the uninstall referenc ...Show All

• Visual Basic Is it possible to make a parent form a child form of another form vb.net?

  Hi! I am new here as well as the programming language I am using. I am working with forms now and I just want to ask if it is possible to make a parent form a child form of another form What i want to do is something like this (grandparent ->parent -> child) When I set the parent as a child, it gives me the error that I can't set the parent as a child. Thanks in advance. You never indicated that you wanted MDI forms :) You can only have one MDI container. You cannot have MDI Containers as children of other MDI containers (which is what the error is telling you). However, you can have forms within forms, as I stated: so your MDI container is the 'grandparent', the MDI Children are actually pare ...Show All

• Software Development for Windows Vista Distributed Workflow using WF

  Hi, I have a sequential Workflow which consists of activities say, A B and C. I need to execute them in a distributed environment i.e. Activity A and C on Machine A and Activity B on Machine B. Is there a built in support to realize this in WF and if not, are there ways to realize this using the runtime services provided in WF Rgds Giri Hello Serge, The approach of what you suggested of runtime subscribing to activity A close event doesn't seem to work. Within the handler of the close event, I tried calling instance.TryUnload(). There is an exception since this operation is not permitted from the runtime thread. So I posted this on a seperate thread using QueueuserWorkItem(), however ...Show All

• SQL Server Checkpoint restart

  I have a package that uses checkpoint restart. It is resposible for truncatings many sets of tables and then loading them. There are several ExecuteSQL tasks to truncate the tables and several corresponding data flows to accomplish the loads. If a load fails I want the corresponding truncate task to be part of the restart otherwise duplicate data may be loaded. Normally, SSIS will start at the failed task. I read something about containers that led me to think that if I put the truncate & matching load pair in a sequence container that the container would be the restart point, but either I read it wrong or it's not working that way. Anybody know how to accomplish what I want to do Mark Cha ...Show All

• Visual C# Why don't we use header file and Main in class

  Hi 1-)In c# why don't we need header files What does c++ miss.So it needs header file but c# not. 2-)In c++ main() is not in a class.Main() is called by OS.It is a special function.But in C# it is also in a class.For example: class Exercise { static void Main() { Console.WriteLine(); } } Here this is confusing thing.Why do C# designers force us to put main in a class Does OS instantinate Example class for calling main().If not what is the magic behind this rule Thanks. ok my first questions answer is metadata.Thanks carlop.
