• Sander Smeenk strange behaviour

  Hi guys, I am definitely a newbiew to .Net, and am having a problem that I cannot seem to get around. I have a single Windows form app that loads several (probably about 10) datatables into a dataset. The dataset is defined as a public. Eventually the data is summarized into a datatable that is displayed into a datagrid. At first I could not get the double-click to work, and eventually tried to add a context menu control to capture a right click. Once I got things wired up, when the menuitem click event fired, I wanted to create a dataview from one of the datatables in the dataset and filter accordingly. To my surprise, the dataset variable has a value of nothing while in the click event. I then figured out how to capture a double ...Show All

• Pooja Katiyar ADO.net dataadapter.fill

  Hi, I have two tables in my database: tb1 and tb2. tb1 will be inserted into tb2 with these conditions: 1.) if primary key to be inserted is already existing in tb2, then the data in tb2 will just be updated using values of tb1 2.) if primary key to be inserted is not yet existing in tb2, a new recorded will be created in tb2. I used a dataadapter to fill the datatable and a bindingsource. Also, I used execute non-query command to insert/update the data in tb2. everytime i update/insert a record in the database, my datatable still contains old table records (it doesn't have the data i inserted and contains old data before updated). in this case, i have to issue another da.fill(mydatatable) to refresh.... which is so slow espe ...Show All

  Hello, I'm developing a program in VB6 where I need do play a wave file assinchronously and 'be advised' when the execution of the sound has finished (receiving an event).

• DotNetDoctor ImageLists and html

  First, my appologies in advance if this isn't the right spot for this post. I tried looking around and searching the forums and didn't spot what I was looking for. I am not into the "html" side all that much and what I would like to do is place the images I have into an ImageList control rather than being stored in a folder someplace. Small GIF and JPG type files. That I can do and understand. If I am writing to a HTML document within my application, how can I address putting those "graphics" into the document. Normally you would use something like <img src="angry.gif" alt="Angry" />. How can I specify that the image source is a location within an image list control rather than a 'file lo ...Show All

• Chidu FileSystemWatcher - Created events fires too early

  I have been playing with a FileSystemWatcher, to start processing files as soon as one arrives in a folder. Specifically, I'm looking for a zip file, then unzip it. However, when I try to unzip a file as soon as I get the Created event, the file has often not finished being written, and therefore I get an error when I try to unzip it. This time period is very short, a tight loop without pauses trying to open it for write will return OK in 3 loops. Question ======= How do I get FileSystemWatcher to raise an event when a file has FINISHED being written, instead of START being written ugly but functional will do for me thanks Jim You say you get 2 events I only get one! Have you added event ...Show All

• DMottorn Recieving 'i??' character symbols when loading text files not containing them

  I am writing a cross-platform application and I am using Visual Basic 2003 Standard for the Windows XP version of the application. My Windows Mobile version writes information out to a text file and my Windows XP version can load and modify them. The text files do not contain the i symboles, but when I load the text files into my Visual Basic application each file loaded has those symbols attached to the begining of the first line I read into my XP application. Does anyone know why this is happening At first I thought my Windows Mobile Program was the culprit but considering the fact that those symbols are not in the text file when I view them (I used 3 different text editors to make sure) so I am assuming it's something I need to ...Show All

• DIMIS283 Converting an Integer to String

  Im trying to convert some integers to a string (which works fine) For example My Funciton MKI is working ok as far as i can tell Dim v1 as String = MKI(116) V1 then equals "t I wish it to equal "t" Can anyone offer any suggestions please Kinda, a propietary date format to save a few bytes. You can use Chr() to go from a 16-bit integer to a string and Asc() to go back. However, the generated string would not be the same, it would just have one character in it. This is only a problem if you need to read data that the old program generated... Only use RtlMoveMemory on unmanaged memory locations. Even then, there are some .NET functions which offer better h ...Show All

• NoobestNoob Procedure View in VB.net 2005 ?

  In VB6 you could set your IDE to either Full Module View or Procedure View. Procedure view is preferred because it allows you to have just the code for just the active procedure in front of you. VB.net defaults to full module view (which floods the text editor with code I'm not currently working on). But how do you switch it to Procedure View I realize Microsoft has removed the SDI interface (which is superior to either the MDI or Tabbed interface they currently have), but surely they haven't left us with just the full module view Well, we don't have procedure view anymore but we do have regions and outlining that helps tremendously in organization and cutting down on the clutter ...Show All
