• SQL Server creating a child row with two parents? (in one column)

  Hi! How can I make a relation that would let me relate an employee to two departments There is a table with emloyees and each one works in a department and there is a foreign key relation in the child (employees) table to the parent (departments) table. So can an employee work in two departments (it's not impossible to imagine, is it ) And how would I retrieve all the employees of a department Or in other words, if I were working on some kind of software for my local supermarket and they need to keep track of all bills they ever gave out. I would make this products table and this bills table. Then I would create a foreign key column in the products table and fill it with bill_ids from the bills table and make retrieving bill items a simp ...Show All

I am trying to use ActiveX from my VB application to connect to the external application which does support ActiveX controls. This external application has provided a library of ActiveX events and methods for this purpose. In my VB application, I have included this under the 'Components' of the tool box as "TWS Control". I include the 'TWS Control' in my VB's custom-built window. The window contins details to seek connection with the external application. In my VB application, I declare the ActiveX library, at the beginning of the code, using ...Show All

• Visual Studio Express Editions Scan my files ? - How do i do ?

  How do i do to scan my files and show in textbox1... Example: Scan files which i want : "abc.exe"; "abc.dll"; "abc.ogx"; "abc.txt"; etc... If you find those files, show in textbox1 . And we create a new button with name "delete" because i want to delete files in textbox1 (delete files form textbox1 and computer) Please post the code well it will be hard to do. you pretty much need some algorithm to scan for viruses and what not which is not easily done. There is no "set" algorithm to do this, you will have to create one. Do some research about how to detect files which could be infected. It's something that's not easy to learn and not easily told. ...Show All

• SQL Server How to display a list with many columns on two pages?

  I have a list with twenty columns. I would like to split the list on two pages. On the first page, i would like to display columns 1 to 10 and on second page i would like to display columns 11 to 20. I tried to use a very large table object, but i don't manage to display the data correctly : the columns on the second page are aligned on the left with no margin.

• Software Development for Windows Vista How can I get Workflow Status from Tracking DB without using SqlTracking and WorkflowStatus?

  How can I get Workflow Status from Tracking DB without using SqlTracking and WorkflowStatus property, but by select  statement from DB Here is some tsql code to get the most recent status value for each activity in a workflow (just change the hardcoded workflow instance id or move the code to a proc with workflow instance id as a parameter).  Activities that have not yet executed (or will never execute, for example in a branch that is not executed) are listed as 'Initialized' and the Context values are null.  Hope this helps.

• Software Development for Windows Vista Where is the Application database to be installed?

  Hey all, According to the Windows Vista Software Logo Spec 1.0.doc ( Version 1.0.0006 ), Item 2.3 "Install to Correct Folders": Applications should be installed to Program Files or the user’s AppData folder by default. For per-machine installations, user data must be written at first run and not during the install. Since the install potentially elevates to a different user account during the per-machine install, there is no correct user location to store data at install time. Our multi-user application is intended to be installed "per-machine", so any user of the machine (or network) could share the application data. That said, can anybody explain in plain English, where should the application ...Show All

• Visual Studio LocalReport Error - A data source instance has not been supplied for the data source

  I have just installed VS 2005 RC. Tried using the LocalReport control using the exact sample code provided in the help for the Render method. I keep getting an error during the LocalReport.Render method call - InnerException = "A data source instance has not been supplied for the data source". The dataset and table supplied is valid as it works with the Reportviewer control. Is there something I am missing or is the sample code wrong The key is to use the Reset method of ReportViewer. ReportViewer1.Reset(); I put it above the LocalReport datasource clear/add and it worked! Took a few hours to find this out! ...Show All

• Smart Device Development keybd_event() drops duplicate characters

  To All, I’ve written a program which takes the input from a barcode scanner and sends it as a keyboard wedge to any textbox that has focus. I’m using keybd_event() to send the characters, and the program works well, unless I have duplicate characters in my character array. For example: FQT-123 in my array displays just fine in the textbox. However, FQT-100 will display as “FQT-10” Or “Q6335-10009” will be read out as: “Q6334-1009” or sometimes as “Q634-109” I’ve tried to remedy this by throttling the FOR loop that iterates through the character array with a sleep(50) for (uiLoop=0; uiLoop<uiCount; uiLoop++) { Sleep(50); keybd_event(bOutput[uiLoop], 0, KEYEVENTF_SILENT, 0) ...Show All

• Windows Forms Graphics are being erased by other windows or off screen movement...

  I have am working on a program that monitors the download speed of ones internet connection and draws the speed to a graph. The graph is a simple line graph that is drawn using GDI+. The graph is updated in the WebClients DownloadProgressChangedEventHandler. The problem is that when I move a window or move the program off screen, the graph, or the portion that was covered or went off screen gets erased. I have tried doing gc->Save(); (gc=my graphics) but that has not done anything for me.

• Game Technologies: DirectX, XNA, XACT, etc. Is DirectX9c realistic for all my UI needs?

  I am currently wanting to use the DirectX 9c UI for all of my UI needs in my game. Like using a MultiListEditBox for a complex trade window tracker editor and also an inventory being able to drag and drop 3d images of my items. Is it realistic Do I need to wait for XNA and how much would it cost I would like to use it for free but if not willing to pay a few dollars. Do I have to use something else like CEGUI or something else Thanks Neither DirectX nor XNA provide any UI libraries. The DirectX SDK has sample UI components in native and managed code, however the code is part of their game template library and tough to extract just the UI elements without using the rest of the library.
