• Windows Forms Form focus problems

  I've got the following problem: I've written a WinForms problem (.NET 2.0), which has a UserControl with a few buttons on it. The form has a KeyUp Event to trap keyboard events throughout the app (works with a barcode reader). After pressing the button, and scanning a barcode (i.e. capturing several number key-presses), the keys are remembered, but the following enter (appended to each scan) is captured by the button I previously pressed as a click. This remains true as long as I don't change the focus to a control that doesn't grab an "enter" key, such as a checkbox. Is there anyway I can avoid this behavior, preferably by disabling the buttons "enter-trapping" behavior ...Show All

• SQL Server Primary Key Question

  I have been developing a .NET Web app with an SQL Server 2005 Express database. Since I've been testing insert and delete code with a large data source, the Primary Key column which is also an autoincrement integer column is now at very large numbers (starting at over 40,000 now). I've tried doing a shrink on the database, but other then reducing the database size, it has done nothing to reduce the Primary Key numbers. Is there a command way to reduce the starting number back to 1 or do I need to completely reconstruct the database from scratch TIA Thank you, Sir. Yes, it did work and in the process I've learned more about SQL Express and T-SQ, important for a relative newbieL.  Not onl ...Show All

• .NET Development getRequestStream() throwing SocketException

  Hello, I posted this in another forum but I believe it may have been the wrong forum to find the answer I am looking for. I am still very much a novice when it comes to .NET and programming in general so please excuse my naivete. I have a Windows Mobile 5.0 app written in Visual C# - .NET CF 2.0 I had a very simple login program that would query a MySQL database on a server and return some info about the user logging in. This code was working fine a couple weeks ago, and I got sidetracked to another project. Well, today I went to do some more work and I noticed that I could no longer login. My database was accessible and my login info was correctly entered. So I did some debugging and noticed that a line of code I had was throwing ...Show All

• Windows Forms how to make the save and exit buttons visually exactly the same

  Good mourning from Seville (Spain), I would like to know which is the best way to do two buttons exactly equals. The same size and separation between them, and i want it to be easy to drop in all my forms (more than 30...). Thanks in advance. Put them in a UserControl, then drop that control on each form. Better yet, design a base form with those two buttons, then derive all your other forms from that base form with Project + Add New Item, Inherited Form. ...Show All

• SQL Server How can I synchronize 2 stored procedures

  I have 2 storeds A and B. in Stored A, I pass a Table and update values into the Table after stored A complete, Stored B will use all values in the table to compute something. But when I run 2 storeds, I cannot synchronize 2 storeds: stored B always start when stored A is running .How can I make sure the store A complete to start stored B. Is there any thing to do that. I commans as: exec sp_stored A @iP, TableTemp exec sp_storedB @sIP, TableTemp I guess you could wrap them in Transactions. Or just call second SP at the end of the first store procedure within the SP. Or have a trigger on first table that runs on AFTER UPDATE and bypass second SP altogether BEGIN TRANSACTION exec sp_stored A @i ...Show All

• Visual C# Disk Partition Volume Names

  My C# application has to pull information on the last partition on the first physical disk drive. If this partition is associated with a windows drive, I have no problem. However, if the partition is not a windows partition (ex: Dell's restore partition), I cannot get information on it. The main piece of information I need is the label. If I look at the non-windows partition in Disk Management, I see the label. Is there a programatic way to get this label for a non-windows partition. Here is what I have done so far: 1. looked into getting it with WMI and found nothing. 2. looked into using the GetVolumeInformation() method in kernel32.dll. 3. looped through volumes using FindFirstVolume() and FindNextVolume in kernel32.dll. ...Show All

• Visual Basic color chart at design time

  Where can I get a color chart that shows the VS KnownColors, to use at design time I want to define a set of color schemes, with colors that I can select visually. I have found some stuff on the internet that gives the RGB values, but I need the VB KnownColor names. Thanks in advance. Johan, Thanks for the reply and applogies for my delay in responding, I missed the alert. ColorEditor does not seem to be what I want. I simply want some tool that will show me a palette of colors at design time, from which I can paste to my code. I think VB 6 had such a window. I am trying to fill in a (fairly extensive) number of enums as follows; Enum ColorScheme1 As Integer LnBaseColour = KnownColor.DarkRed LnParColour ...Show All
