• Windows Forms Where should I put the global variables?

  Hi all, First step, I created a simple "Windows Form" Form1 project. There is Form1.h, and I have many functions like click(), paint(), buttom_down()...in it. How to pass the variables between these functions Should I use global variables or they are not recommanded For example: The program tries to get the screen size and pass into image display function I will have scr_width, scr_height, img_src_width, img_src_height, img_scr_width, img_scr_height, Bitmap^ img... What is the good way to set up them And the second step will be, I separate the buttoms and display area, should I use two Forms If so, how do I pass these variables between so many functions in two Forms Thanks! ...Show All

• Visual Basic modify data, and update datagrid!

  Hi, I am having a problem updating and displaying data. On a form, i have a data grid which, when the user double clicks on a record my data table updates. For this i am using the following commands: dt = Me .FantasyDataSet.Draft dt.Rows(position - 1).Item(Team) = player & ", " & pts dt.AcceptChanges() As i step through my program, i can see that my datatable, dt, is being updated with new values. i have another datagrid which i want to display the datatable i just updated, but it never updates.

• SQL Server Errors using multiple parameters in a SQL Statement

  In an OLE DB Source in an SSIS package, we are having difficulties using multiple parameters in a SQL statement. Using a single ' ' works fine, but I've read that when you want to map more than 1 parameter you should use 'Parameter0, Parameter1, etc'. The problem is that when we use Parameter0 and Parameter1 and then try to map it, it says that the query contains no parameters. Can anyone help with the correct way to use multiple parameters in a SQL query that's part of an OLE DB Source task Thanks, Mike   Rafael Salas wrote: Phil Brammer wrote: You still use multiple question marks ( ) as parameter markers in the query.

• SQL Server SQL Analysis Services Service does not start

  I have installed SQL Server 2005 Standard Edition for use with Team Foundation Server. I have verified the installation according to the documentation, and all is well except that the Analysis Services Service is not started. When I click Start, I see the progress bar as if it is starting, but it stops shortly after, saying that "Some services stop if there is nothing to do". Team Foundation Server requires that this service be started for the installation to succeed. How do I get the service to stay started Thanks in advance.

• SQL Server Flat file connection is skipping columns

  The data file contains column names in the first row. Excel imports the file correctly. I can see the tabs in UltraEdit32. But...the flat file connection just skips over a column. In the preview window, it appears to skip the column entirely. However, when the data is imported, data from the non recognized column goes into a column that is mapped to receive data from another column shifting the data in to the next column. I am using the CopyColumn and the SQL Destination controls. Any ideas on how to make this work Thanks, IanO ...Show All

• SQL Server How to copy structure of database online

  Hi! I have to add a new functionnality in our Web application but i have no idea how to do it. What i have to do is to allow user to create a copy of the BD currently use and to save it on a new name. What i need is only the structure not the data. I need to copy all table, view, function and stored proc. I have no idea where to start. I found on this forum post where it says to detach then copy and the attach the BD but i can't do to this because i don't want other users on our web application to lost the connection with the DB. So was is the best way to do this Thanks !! Thanks !! This is exactly what i was looking for. I have another question. When i iterate for all my tables for ...Show All

• Visual Studio 2008 (Pre-release) A question on DataContract

  Hi! I'm new to WCF, and I've got a question regarding DataObjects / DataContract. As far as I understand, DataConract provides a way to send custom objects, serialized in one of the formats, across the wire. So, at the server side I could have data objects that implemented properties and methods to manipulate those properties (or at least setters with some business checking). That's good. Now, if I build a proxy using VS2005, it reads the contract and constructs a "copy" of my class, with all the published properties, but of course, all business logic goes away. That is logical in many ways (louse coupling, interoperability,...), but let's say I'd like to use the same implementation (shared data objects assembly ) on ser ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. World to screen coordinates?

  To cut a long story short, I need to obtain the screen position of a point that has been transformed by the view and projection matrices. My vector math is pretty rusty, and I am not sure how exactly to go about it. Could anyone give me a hand Once you've got your point transformed by world, view, and projection the rest is pretty straightforward: Your point is P = <x, y, z, w> Start off by getting x' = x/w and y' = y/w If either x' or y' is outside the range [-1, 1], the point is off of the screen - exit Grab your viewport rectangle V = <vx, vy, vw, vh> (that's x offset, y offset, width and height) The screen coordinate S = <sx, sy> is computed as follows: sx = (x' + 1) * (vw / 2) + vx ...Show All

• SQL Server Merge replication between same schema databases but different data

  Hi all. I 'm trying to set up merge replication between two servers that have the same schema databases. The two database have the majority of there data the same but as well as data inserted at a later time independently on the two servers.

• Visual Studio 2008 (Pre-release) WPF Validation

  Paul Stovell has post a good article Validation in Windows Presentation Foundation about Validation in WPF. But, when I test the demo, I find a limitation to validate data in that way. Suppose I have 10 TextBoxes and many other UIElements on a WPF form. For the first time, I binding these elements to null-value data object, so all the TextBoxes are empty. The simple validation is to make sure all the TextBoxes are not empty. Then I click on a Button "submit" directly. Since the TextBoxes are never focused, and the Text in them never be modified, UpdateSourceTrigger.LostFocus and UpdateSourceTrigger.PropertyChanged can not be used. But if I use Explicit, does that mean I should write tens of codes to vaidate the Bindin ...Show All

• Visual C# Layering an Onpaint Event?

  Hi, I'm creating an application with gps-coordinates. Everything works fine but it goes very slow to redraw the panel with : 1) a background 2) a grid (line X and Y, not a datagrid) 3) and a circle wich represents the coordinate. When I click on play the circle starts (slow)moving and you see that the panel is refreshed all the time. The background and the grid do not change and take alot of processing. So I thought it would be handy that those two "layers" are drawn the first time but when playing only the circle is updated. Is this possible Grtz, Annihil8 Hi Matthew, Very interesting, but I'm not sure if I understand it completely. How does your method differ from, for instance, the sug ...Show All
