• Visual C# Newbie question: Passing TextBox value in SQL query

  I wrote following code, but it displays an error where I am passing the TextBox value. Please help: ---------------------------- string qFind = "Select * from FamilyType where FNM like '" & textBox1.Text & "%'"; ---------------------------- You are probably passing a string that contains an apostrophe. As a rule, you should not build your queries from strings, always try to use parameters. SqlConnection conn = new SqlConnection (myconnectionstring); SqlCommand cmd = new SqlCommandd ("select * from FamilyType where FNM like @Pattern", conn); cmd.Parameters.AddWithValue ("@Pattern", textBox1.Text + "%"); ... Edit: I just noticed you are joining your values with "&". That's VB... In C# you j ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render part of an object. + Setting transparancy of a texture.

  I have 2 questions, first one: If you have a normal UserControl (No DirectX yet) and paint a box inside it with GDI+, every part of the box that is inside of the Control is visible and everything else is not. I want to acomplish something similar with Direct3d. As you can't use UserControls with direct3d, I've made my own class that contains a Rectangle of where my object should be located. I want everything that this object paint to be visible only inside this rectangle, if half the object is outside i want that part to be invisible and the part that is inside to be visible. R ight now i only do a check if the Boxes is inside the bounds where it should be visible, if it is I render it. But this doesn't look very good b ...Show All

• Visual C++ Separator in a context menu

  Hi all, How do I add and locate a separator in a context menu (of the mouse right button ) E.g. I wish to separate (between two lines) my own menu items (in the context menu) from all the others.

• .NET Development What's wrong with this XML construction

  I'm trying to upload data from a PDA data store to a remote server, and am writing an XML document to transmit the data. The data is stored in two tables, a transaction summary for each transaction, product level details for that purchase. I transmit multiple transactions at a time. The XML I'm creating for each transaction looks OK, but when I try to append this node to the document, it fails with an 'Invalid ChildType' error. I create my XML by first creating the document ( xdoc ) doing the minimum initialization, then making repeated calls to xdoc.CreateNode(.. ). It has always bothered me that I create a node at the document level but then add it to a child node, but I've never had problems with it. Any help is greatly appreci ...Show All

• Visual Studio Express Editions Long Delays when accessing files

  Anytime I attempt to retrieve a file, or save one, VB2005 Express first does a real long access to to net, sometimes it's so resource intensive it freezes my computer, then eventually alows me to continue navigating to the file. If I disable my network adapter it acts normally. What is ittking for and how do I make it stop. Hmm, I've seen this behavior on networked PCs in a workgroup. Windows XP often has trouble locating a PC by name, even if the network share is mapped to a drive. I think it has something to do with none of the PCs volunteering to become the "master browser"; XP takes a long time to make up its mind where the PC might be located. I got rid of all this misery by giving all the P ...Show All

• Visual C# How to retrieve export information from unmanaged dll?

  Is there exists any tool that can extract marshal information about all exported cpp-functions from unmanaged dll For example: someexptool.exe unmanaged.dll managedwrapper.cs someexptool.exe crypt32.dll crypt32.cs in crypt32.cs we could find something like : [ DllImport ( "crypt32.dll" , SetLastError = true )] public static extern bool CryptMsgUpdate( IntPtr hCryptMsg, byte [] pbData, int cbData, bool fFinal); [ DllImport ( "crypt32.dll" , SetLastError = true )] public static extern bool CryptMsgClose( IntPtr hCryptMsg); and so on.

• SQL Server Web Replication From SQL 2005 Express

  I have tried to setup Web replication following the instructions in the articles in SQL Books Online, using RMO. I am able to create the subscription, but when I try to sync it I get the following error. The process could not create file 'C:\DOCUME~1\lsimpson\LOCALS~1\Temp\HNTBW115D$B_borings_BoringsAll_C:\BORINGS\BORINGDB.MDF\' due to OS error 123. Is anyone familiar with this error If I can solve it, I think the replication will work. I changed the database name to BoringDB and that fixed the original problem. I was able to create a subscription using SSMS and sync it. I am getting a new error when I try to sync with code. I will open a new thread if I can't solve it. Thanks for your help. ...Show All

• Windows Forms Displaying Database information in ListView

  I created an address like database with first and last names and include a photo location in the database. Now I want to use ListView to display the photo and name of each row(person) in my database, but I don't know how to retrieve a string from a single cell in my database. can anyone help ok you are using VB.NET so.... Me.ListView1.DataBinding.Add(ListView1, Firstdatabasedataset.Tables(0), "FirstName") I still think this will not work, due to the first parameter - it expect a string property name, not an object. However at this stage I am unsure what the parameter should be. The other alternative is the way I had suggested earlier - go through each row and get the current row columns' cell value ...Show All
