• Visual Basic Getting a listbox selected value from a seperate form

  Hi all, I'm having a rather strange problem with listbox.selectedvalue. I have a form (Form1) that has a listbox populated with values from a database. I also have a button on Form1 called 'delete'. When you select a listbox item and click delete it brings up a new dialog form (Form2) thats asks if you are sure you want to delete the selected item from the listbox/database. You can choose 'Yes' or 'No' via two buttons on Form2. When you click the 'Yes' button, it calls my deleteItem() subroutine from Form1 which deletes the selected listbox item (note: this code works fine and has no errors if you call it when you click 'Delete' from ...Show All

• Visual Studio 2008 (Pre-release) How can I put one canvas on top of another? or How can I draw multiple layers in the same area?

  Pretty new to graphic dev, so please bear with me. I have an animation (a wheel with colored circles on its outer edges, that spins), which I accomplish by drawing a large ellipse, and some smaller ellipses (sp ). I do this on a transparent canvas, then I rotate the canvas. Conceptually, what I would like to do is draw an opaque rectangular structure over the animation layer, but provide a small "hole" or view through the opaque layer so that you can see the underlying animation. I can't seem to draw over an existing canvas though. To summarize, I want to display a 2D box with a spinning wheel inside of it. A hole in the ...Show All

• Software Development for Windows Vista Ifelse activity in workflow

  How can I set the condition for the ifelse activity . how do I invoke the branching based on the condition. Raskal, I ended up writing an IfElseActivity of my own, due to an additional requirement I had. My requirement was to select multiple conditions for the branch, and I also wanted to pass parameters to the conditions. So I implemented an ifelse activity that takes conditions in the form of activities that implement an interface called IConditionActivity.

• .NET Development Datareader and class'ing

  I am trying to find a way to class my datareader code. the code opens the DB connection and reads the information. then the datareader is used to populate a listbox. is there a way to return a datareader from a class file when I try doing so with 'private void ReadDatabase(string Command)' I get an error that void does not return a value. obviously private int would not work or other similar calls. So how do I return the reader I have to allow the calling code to populate the listbox because there are actually 3 listboxes that will use the code. each listbox has different names and has different database commands. ...Show All

  I asked this earlier, but didn't get an answer. I'd really like to figure this out. It seems like it shouldn't be too hard to do. I'm making an application to keep track of recipes.

• SQL Server DTS DB2 Dates 0001-01-01

  Hi, I am trying to transfer a table from DB2 to SQLServer 2000 through a DTS package. The DB2 table contains fields with default dates of "0001-01-01". The DTS package errors out whenever it reads this date as "invalid data value". In SQLServer 2000, the date fields are of type ShortDateTime. I have searched the Internet but did not find a workable solution. Please, can anyone help me find a solution Older applications sometimes used dates like '9999-12-31' or '0001-01-01' to signify that the date was either NULL, invalid or not-entered. If DB2 is using that date as a valid point in t ...Show All

• SQL Server Replication of Great Plains Data

  Hi All, We have the requirement to replicate financial data to Aus from the UK, however I dont know if Replication is the best solution around Reason why I ask this, is that to create the publication, there are in excess of 10000 articles, which takes forever and a day to create, then when setting up the push subscription, this takes equally as long. DB's physically range between 100MB and 2GB. Link to Aus is 2MB E1. The accounts server isnt the most powerful of beasts (HP DL380, 1x1.4Ghx CPU) and with 4 DB's to setup and replicate, it's going to take some time. With this in mind, I would also be looking to script out the publ ...Show All
