• Visual Basic Optimizing Search

  I am using VB.NET 2003 and MS Access. I have a TextBox and below it is a ListView control. As the user types a character in the TextBox, the records starting with that character get filled in the ListView control. The records are fetched from either Oracle or Access database. Previously, I used to execute a SQL query, which looked something like this: "Select FirstName from TableName where FirstName like '" & TextBox.Text & "'%" This query was set to execute as the text in the TextBox changed. If the TextBox is blank, then all the records get displayed on the ListView alphabetically. Now I have decided to use a different approach so as not to query the database again and again. Now what we are doing is that ...Show All

• Software Development for Windows Vista In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0. I have written a simple routine (shown below) to interrogate the current state of a workflowinstance: public string WfCurrentStateDescription(string WorkflowInstanceId) { // Get the workflowRuntime which was started in global.asax WorkflowRuntime wfRuntime = (WorkflowRuntime)Application[WorkflowRuntimeKey]; StateMachineWorkflowInstance wfInst = new StateMachineWorkflowInstance(wfRuntime, new Guid(WorkflowInstanceId)); return wfInst.CurrentState.Description; } I find that, once I have called this on a workflowinstance, that instance gets "stuck" in the current state and never transitions to the next state, even though code appears to get c ...Show All

  Can someone advise on how I should build this. the requirement is to build a text file from a table (1500 rows & 15 columns) I need to loop through the rows in a table adapter based on a parameter and for each row in the table adapter I need to write each column of each row into one text file. thx in advance http://msdn.microsoft.com/library/default.asp url=/library/en-us/cpguide/html/cpconWritingTextToFile.asp It would probably be easiest to use StreamWriter because all you are doing is creating a text file. ...Show All

• .NET Development Problem with TableAdapter Updating Database

  I am porting a database program from VB6 to VB 2005. I have decided to rebuild the forms from scratch. I am trying to use the drag and drop features to build the first form. The form has a detail section for one table, and a DataGridView for the second table. The database is an Access database. The two tables have a Relationship defined between to employee ID fields with a foreign key contstraint. When I use the BindingNavigator delete button to delete a record, both records in the two tables are deleted from the DataSet and the form, but when I reload the form, the records are back. I've tried using the default code created for the Save button, as well as writing other code to try and make the TableAdapter update the database, but with ...Show All

• Software Development for Windows Vista [edit controls] What is EM_SETHILITE supposed to do?

  Hi, watching the list of new COM interfaces, API functions, window messages and so on, I noticed EM_SETHILITE and EM_GETHILITE.

When running this app on Vista RC1, I can't detect any hilighting on the first 10 chars. Is this an Aero Glass only thing I'm running Vista inside VMware and can't use Aero Glass.

• Visual Studio Express Editions Few Questions.

  Well i got 3 questions. 1) In Vb i used to do "Exit Sub" how can i do that in C#. 2) And in VB ( VB6 ) i used to do the WITH ("someting") code to write less code wen i use same COM how can i do that in C#. 3) How can i show MessageBox or do someting like Application.Exit(); in a Class. thx ahead To use MessageBox and Application in your class, put this line at the top of your class source file: imports System.Windows.Forms; You can emulate the With keyword in C# through a variable. For example, in VB.NET: With Me.TextBox1 .Text = "nobugz" .SelectionStart = .Text.Length End With In C#: TextBox t = this.textBox1; t.Text = "nobugz#" ...Show All

• Visual Basic how to spell & grammar check forms

  I've made a form in MS Word 2000 that's locked. This way, coworkers can fill it out on their PC, then print a hardcopy for our files without accidentally deleting portions of the form.

• SQL Server How extend excelRendering

  HI, I have a problem. In my report I used a custom funcition to convert seconds to string (because I want to show the amount of hours.. if I use format hh:mm:ss when the amount is greater than 24 exaple 25 this format shows 1 as hour)... now, when I export the report with excel I have the necessity to have DateTime and not string. There is the possibility to extend the excel rendering Can this help me Have anyone some idea Thanks I think you would want your custom function to return the type System.DateTime. Then when the Excel export looks at the value of the textbox, it will see the DateTime type and put that into Excel as a date. You will probably need to apply formatting to this in the Format property ...Show All

• Visual C++ Marshalling

  I have a native byte* buffer which I'm going to pass to a MarshalByRef object on a remote server (using .Net Remoting). I know that if I implement the MarshalByRef object in a way that it accepts a byte* too, it will complain that I cannot pass pointers to the server (which is absolutely right). So what would be the best replacement I myself used a cli::array<Byte>^ and used Mrshal::Copy() like this: int MyClient::Write(Byte* buffer, int size, unsigned long * writeNo) { array < unsigned char >^ aBuffer = gcnew array < unsigned char >(size); IntPtr^ ptrBuffer = gcnew IntPtr(buffer); Marshal::Copy( static_cast <IntPtr>(ptrBuffer), aBuffer, 0, size); ... m_W ...Show All
