• .NET Development data multiple bursts?

  Hi. This is a question I've been meaning to ask but then sometimes able to resolve it by adding a small delay before sending the next message. I have a server/client app client connects and sends data via the network stream.   .. this .theNetworkStream.Write(bytesOfData, 0, bytesOfData); this .theNetworkStream.Flush(); Thread.Sleep(140); //small delay     this works fine when sending 1 piece of data at a time, but when sending it in a loop, sometimes the data is sent properly whilst other times the data for some reason is recieved at the server end in 1 big string, instead of chunks of data, even with the delay from the client.   When recieving  data on the server, I am doing ...Show All

• Visual Studio Express Editions Networks & Service Pack 2

  When I tried to install VB Express on a computer in my lab, it asked me to install Service Pack 2. Now I'm getting an error and the internet is really slow. After talking with the tech guy, he told me that Service Pack 2 is not good for networks. Is there anyway around this I've never seen that before or even heard SP2 was bad for networks! I personally disagree with that but lets not go there. What is the error you are recieving on the computer that HAS SP2 and installing VBExpress ...Show All

• Visual Studio Team System Managing Deployment across the Enterprise

  Are there any suggestions or recommendations of ways to manage a database deployment using Data Dude. It seems as though the Schema Compare tool works on an all or nothing basis. Consider the following scenario: Team A check out a number of objects for development. Team B check out an object, modify it and check it back in, but do not wish to deploy at this stage. Team A check in, perform a get latest version and run the Schema Comparison tool to create an upgrade script. The tool will pick up the changes made by Team B (and possibly others) and include these in the deployment script. It is possible to skip those objects that aren't part of your project, but this seems like an arduous and error prone way of managing the rel ...Show All

• .NET Development Define an XSD relation to columns in XML?

  Looking for some hints about an XSD format that would translate the XML below back into a table: <Column INDEX= "0">ColA_Name</Column> <Column INDEX = "1">ColB_Name</Column> <Row> <Cell INDEX = "0">DataA1</Cell> <Cell INDEX = "1">DataB1</Cell> </Row> <Row> <Cell Index = "0">DataA2</Cell> <Cell Index = "1" >DataB2</Cell> This represents the table: ColA_Name ColB_Name DataA1 DataB1 DataA2 DataB2 The key here seems to be getting the "INDEX" attribute recognized as a reference, but I haven't had any luck establishing that in an XSD. So far, the XSD that seems to make the ...Show All

• Visual C++ RUNTIME ERROR

  Environment: Visual Studio 2005 Language: C++ /clr Type of aplication: Console I am experiencing a very strange and theoretically impossible situation. My application runs fine under IDE, both in Debug and Release mode, but when I run the release version from the command prompt, I get an error. Aside from the fact that I probably made an error in my program, in this situation the very purpose of the debugger is void if it doesn't detect it! And it is very strange that exactly the same application, with exactly the same inputs, performs differently when run inside IDE or by its own. I know that troubleshooting my program will then be very difficult. I am reluctant to pass all my program because it is fairly large and complex. ...Show All

• Visual Basic Help Needed with VB6 Data Type to VB05 Data Type Conversions

  Hello, I'd like some advice on solving a problem having to do with data type size changes when moving from VB6 to VB05. Specifically how do I convert the VB6 data type to the VB05 data type A simple one is VB6 "Integer" (2-bytes) is a "Short" in VB05. With VB6 the "Date" (8-bytes) appears to be (7-bytes) in VB05 (My data on its size seems to vary). With VB6 the "Currency" (8-bytes) is replaced with "Decimal" (16-bytes). My current project requires me to read a binary file made up of an array of different VB6 data types using a VB05 based program. I created a new Structure with VB05 data types and read the binary file. My data appears corrupted due to the differences in s ...Show All

• Visual C# A little confused.

  So I was writing a class that takes it so when you click and hold the mousedown on a control the whole form will go with the mouse. Well, I came across something weird. I get the initial coordinates and translate them via: mousex = Form.MousePosition.X - Panel.PointToScreen(Panel.Location).X; mousey = Form.MousePosition.Y - Panel.PointToScreen(Panel.Location).Y; Then I have a simple timer, that takes the mouse position - thesevalues and move the form there. Well I'd think it would work smoothly. However it doesn't... it was 4 pixels off. So I wrote in a simple thing that added 4 pixels on the above 2 lines of code and it worked perfect. I recently came back to this and decided to write my own function for putting the coordi ...Show All
