• .NET Development New column problem....!

  I made a procedure Public Sub Novo(ByVal nova1 As String, ByVal nova2 As String) that creates a new oledbDataAdapter with insert update select and delete commads. I also added that commands can change depending how many columns are in a Table (insSql). Dataset is Studenti1data, I made it by the new data source wizard,and made datagridview and bindingsource draging Table1 to Form2. I use Access database. I add a new column with this code: Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Dim noviStupac As Data.DataColumn = New Data.DataColumn("Test Marko", System. ...Show All

• Windows Search Technologies click on go button doesn't work

  Hi I just upgraded from 2.6.6 to 3.0.1 on windows xp sp2 and when I click on the go button, it doesn’t open the full screen search. I removed it and reverted back to 2.6.6 and now my desk bar doesn’t show up either. So I put the 3.0.1 back again and rebooted. Under desk bar, you can see the search box and go button. Searching on box works fine but clicking on magnifier or clicking on search desktop has no reaction. Any idea how this can be fixed ...Show All

• Visual Basic How to connect to current active Excel Workbook from standalone Visual Basic program?

  I have an application that needs to verify if Excel is running ( doing this through System.Management.ManagementObject iteration) and if it is, to connect to the currently active workbook and fetch the list of worksheets. I cannot for the life of me figure out how NOT to say Dim xlApp As Microsoft.Office.Interop.Excel.Application xlApp = New Microsoft.Office.Interop.Excel.Application xlApp.Visible = False xlBook = xlApp.Workbooks.Open(xxx) but rather something like xlBook = Microsoft.Office.Interop.Excel.Application.ActiveWorkbook (I know that is wrong but that's the best I could think of). Can you please show me how to set xlBook to the currently active Excel Workbook Found the answer aft ...Show All

• .NET Development Abortable thread with return value

  Hello, There are two possible solutions that would work for me here... Requirements are as follows: I want to run a task in the background. The task returns a value, which I need to collect. I also need to be able to abort the task. I can use Thread.Start, and then Thread.Abort if I need to stop it, but I can't find a way to get a return value by this method. Alternatively, I can use BeginInvoke, which makes it easy to get a return value using EndInvoke, but then I can't seem to find a way to abort the thread. Either method would be fine. Any suggestions Thanks, Nick Nick, I realize your question is answered. I am just curious if you can give a very broad description of the application yo ...Show All

• Visual Studio Express Editions Moving On

  Moving on from my last post, where I wanted to draw an ellipse in Picturebox1. I now want to copy the part of the image that is inside the ellipse and move it to picturebox2. I've been looking at Transform and Translate examples but not sure how to adapt them to what I'm after. Most of them just show you how to draw a rectangle and move it 100 pixels to the left. Some pointers please would be helpful. Actually, as I look at talldudes code, it looks like he really did talk to the buffers instead of inscribing images on a picturebox surface which is fine to do although Powell clearly recommends doing this kind of thing in a paintevent with an event supplied graphics. This goes back to an answer tha ...Show All

• Visual C++ error while registering an exe on vista

  Hi everybody,       I am getting error while registering an exe on Vista. Faulting application query.exe, Faulting Module Querydb.dll, exception code 0xc0000142, fault offset 0x000089f3, etc. It is properly registering in xp, the code developed is from vs2005 (vc++).. Please help me in resolving the problem. TIA, with Regards, Ravi Mudhol. Hi, registering components normally writes into HKEY_LOCAL_MACHINE\Software\Classes which a normal user cannot do. Maybe even an admin without explicitly giving full admin rights cannot do that if UAC is enabled. You can open a cmd.exe with full admin privileges: create a shortcut to cmd.exe on the desktop.

• SQL Server Create a cube- only of linked objects ?

  How do you create a new cube, that only exists of linked objects. As i see it, you can only create a cube by selecting source, fact table etc. - and then afterwards add linked objects to the cube.... Hmm seems like the easiest way is to create a cube, is to select at fact and dimension - finish and the delete those again. Then you have e "blank" cube and can add the linked objects.... ...Show All

• SQL Server Combining Multiple Subreports in One Report

  Hi, I am trying to combine 5 different reports in one report. I am using them as subreports. The problem is, they are all different formats. For example, one of the report is rendered as 3 column report, and page length and width vary from report to report. When I tried to use table and list for this, my program crashed and closed my visual studio. When I use rectangle for it, then shows me the report but report is no more multiple column and page sizes were also different from the one I did in the report. Please guide me how to combine all these reports and not loose the formatting of the reports. Thanks, -Rohit Hi Robert, Do you think its going to be fixed If yes, then how early you think it ...Show All

• .NET Development .NET 1.1 vs .NET 2.0 behaviour with Image fields

  In not .NET 1.1 and 2.0 the System.Type mapping for a SqlDbType of Image is byte[]. If you use this type to create a SqlParameter (with a value of DBNull.Value) and then use this in a SQL statement of the form "Update table Set ImageField = @parm where ......" Then in .NET 1.1 it works, but in 2.0 you get an Exception "nvarchar is incompatible with image" How can you determine the correct System.Type to use for Image fields, and why is the behaviour now different The application code is generic and not tied to specific database designs. Thanks Tony sorry if I am being confusing/misunderstanding, I apologise. From the code snippet, you are inserting a b ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Missile Command - XNA Remake

  Max Damage Studios is now making its release of its Missile Command XNA remake public. You can go directly to our downloads page to grab it. This project was mostly a proof of concept written in a very short, around 10 hours, amount of development time. We made use of a few of the DirectX SDK Tools such as XAct to get the final result. All audio work was done in our studio. There are only 11 levels in version 1.0 currently, but perhaps someday we shall extend that and produce another version. But we are moving on to our next project for now. I can't edit the above post because the forum is being strange...but here's the correct linkage for the sound pack: Max Damage Studios - Audio Page ...Show All
