• Visual Basic Error Message that I can't resolve...

  I am fairly new to writing in VB and in reality it is actually my first true language that I am trying to learn. I am currently writing a small application for where I work that will be used internally by only a couple of people. The purpose of this project is to record and maintain records for troubleshooting calls. This is in essence a CYA (cover your *ss) ploy that also helps us maintain with compliance rules. So essentially what I did was create a small program that would refernce back to a database out on one of our servers. This was supposed to be something that I assumed would be very easy, and at first it did seem to be working properly. Now I have run into a problem that I do not have a solution for. The following is the error I g ...Show All

• .NET Development What is the best approach for mapping external data? Any ideas?

  Hi all: My boss and I are having discussions on what is the best way to migrate data from one (unknown) database to our database. Let me explain: We are looking to develop an application that should be able to attach to any ODBC database to grab data or individual records and import them into our database. Here's the problem, we may be unfamilair with the database or how the tables are laid out, we don't know where the data is located (up to their DBA), it could be normalized where our database or table is not, etc... I wanted to have the DBA for the database we are attaching to create a view of some sort or "export" the data into a specified format and then our application just do a field-to-field read into our da ...Show All

• SharePoint Products and Technologies Cannot Access _layouts on sharepoint

  I have been working on our Sharepoint Server with Project Server 2007. We are using this as a test platform and will probably be purchasing the software and server in the near future. Here is the background then onto the problem. We have 2 distinct forests and had problems getting people in forest1 able to access the server in forest2, even though we are planning on everyone migrating to forest2 in the coming months the powers that be decided we would not be migrating the test base to the new forest yet. While working out the problem, I somehow locked myself out of being able to use any file in the _layouts directory. So things like Site, People and Groups, Site Hierachy, Personal Settings & Server Settings all fail with the ...Show All

• SQL Server Custom Data Flow Component Column Mapping Question

  Hi, I'm having my first go at developing a destination adapter which will send data to an update Web Service. I've got some rather big gaps in my understanding. I've been following the various samples I've found on the net and have validated my mapping and picked up all the available column names and datatypes which are appearing in the Input and Output Properties tab of the Advanced Editor but I only have a tab for "Input Columns" and not "Column Mappings". Which method defines the availble columns for the user to map Let me know if I haven't given enough information. cheers sorry - I had searched already but somehow missed this post which answered my question: http:// ...Show All

• Visual C# How do i use keyboard shortcuts and use cut, copy, paste, and undo?

  Can someone show me a couple lines of code to make shortcut keys. Also it would be handy if someone can show me how to write some code to use undo, cut, copy, and paste. Thanks. well the cut/copy/paste is usually in the Control that is TextBox based... this.theTextBox.Paste(); this.theTextBox.Copy(); //you need to set the selectionstart/selectionlength properties so it can copy it from that. in regards to shortcut keys - in what sense The standard Windows shortcut keys for cut/copy/paste still apply even for your app as they are standard Windows shortcut keys. Otherwise to make your own I guess you need to implement the keydown event of the control and check the KeyEventArgs for which key they pr ...Show All
