• Visual C++ DeviceIoControl FSCTL_ALLOW_EXTENDED_DASD_IO returns false

  Hi, CString str = \\\\.\\CdRom0 ; hCD = CreateFile (str, GENERIC_READ| GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); status = DeviceIoControl(hCD, FSCTL_ALLOW_EXTENDED_DASD_IO , NULL, 0, NULL, 0, &returned, NULL); The above DeviceIoControl returns false. Any one knows what , I am doing wrong. I tried this above after ReadFile failed for some sectors of a file in a single file CDROM.

• Windows Forms Throttling a Windows Form Application

  I have a Windows Form application that implements both BackgroundWorker and standard Threading. System.ComponentModel.BackgroundWorker System.Threading.Thread The BackgroundWorker objects are used to update the UI. The classes I made that run the long processing are threaded and have events that are raised as updates are made and when the threads complete. The BackgroundWorker sits and waits for these raised events, then updates the UI so the user can see the progress. All pretty straight forward stuff. I want to take this to the next level and implement processor throttling. Some of these actions can take many minutes, while potentially others could take hours. I want the machine to continue to be usable by other processes. The a ...Show All

• Visual C++ F1 help -> "Inforrmation Not Found" ?

  The online help seems to show me the "Information Not Found" page quite often, even for things that it seems to find.  For example, in a .c file I hilight "EnableMenuItem" and hit F1.  I get the "Information Not Found" page, but down in the "Index Results" window it shows 1 topic found, and I just have to click on it, and then it shows up in the main help window.  Why doesn't it just display this instead of telling me information not found Maybe I don't have something configured right   Any help would be great.

• Visual Basic Please Help me with my ComboBox columns

  Hi I have a DataGrid with ComboBox columns. I want the same thing to happen as when a user clicks and chooses an item in the ComboBox. When a user stands in the last row (new row) and clicks for choosing an item, a new row appears beneath. I want the same thing to happen when a user types in what he wants, as what you can do in Access ComboBoxes, and when he leaves the ComboBox a new row appears. Is there a way to make that happen   I have tried to explain my problem in so many questions; I hope I got it right this time.   Fia If you are using the DataGridView in VB 2005, you can handle the "CellLeave" event on the data grid view which should fire w ...Show All

• Visual Basic Not able to save data to database

  I am thinking that this is actually a very easy issue, but I can not figure it out and am hoping someone can help me. I have a database setup with no data yet. I am able to connect to it and everything fine through Visual Studio/VB 2005. I built a Windows form that I want to use to Add records to a table. I followed examples from books on doing this by taking the "Data Sources" table and dragging it onto the form. When I run the the project, the form comes up with the add record button active. I click that and add data, skipping over the auto-increment field. The Save Data icon never becomes active and if I click on the Add New icon again, I get an error about the auto-increment field not being allowed to be null. When I ...Show All

• Architecture Data Access layer generation tool query

  Hi Everybody, I am evaluating on various optimistic locking mechanisms for implementation in a DAL code generating software. First Approach : All column based locking .I see following demerits: 1.Can't compare CLOB and BLOB columns 2. Every column of the database entity(table) should have a value set. 3.We have to preserve the old values so extra memory overhead. Second Approach: Timestamp column based locking : I see following demerits: 1.If we go for timestamp based locking ,then we have to create an extra column or an extra table for timestamp of all tables.I think by introduction of rowversion in sql server, the problem of extra column is solved now atleast for oracle and sqlserver.Not sure about access a ...Show All

• Smart Device Development Info for DirectX on WinCE 5.0

  I am researching which fast graphics engine I can use for devices running Windows CE 5.0 and higher. (note: i am not referring to winmobile devices like the PPC, etc, but generic CE devices). Can anyone tell me the following: 1. Does DirectX support ALL generic CE devices v5.0+ 2. Does DirectX come pre-installed on these devices If not, can I redistribute DirectX easily as part of our installation 3. If it does come pre-installed, is this something that the hardware vendor must guarantee for us Or is it "just there" as part of the base CE operating system 4. Are there licensing concerns for using DirectX on WinCE devices 5. Technically, what modules are required for DirectX to be used What d ...Show All
