• Visual Basic Limits on Memory Use?

  Hi all, I was testing the VB2005 Express and decided to create a large array in the IDE. My 32bit XP Pro machine has 3.5GB available and I thought I'd check to see how much I could use with VB. I understand that there is a 2GB process limit, but I thought I just check that out. My code: Class Form1 Private Sub CreateArrayToolStripMenuItem_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CreateDataTableToolStripMenuItem.Click Dim bigarray(1000000, 250) As Single End Sub Private Sub ExitToolStripMenuItem_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click End End Sub Private Sub Form1_L ...Show All

• Visual Basic Updating bin/debug and bin/release After Rebuild

  I am developing a VB 2005 windows app. When I make a change and then build the project it does not automaticallu update the stuff in bin/debug and bin/release folders. I can manually copy everything from the project to the bin/debug folder and then hit F5 to test my changes. There must be an option that I have not set properly but I cannot find it.

• Smart Device Development .NET Compact Framework v2 SP1 Patch for VS 2005 is now available.

  Q. What is that exactly A. This is a patch (as in difference between old version and new one) for NETCF V2 RTM which updates existing NETCF V2 installation to SP1. It is intended for VS 2005 users only. Q: I've copied this patch to my device, but it won't install. Is that because I'm low on storage memory A: No, that's because this patch is for desktop , not for device. Please install it on desktop, do not copy it to device. Patch would update original NETCF MSI (which is also for your desktop) to SP1 and VS would deploy changed NETCF CAB automatically. Q. Is there a difference between updating existing installation with this patch or uninstalling it and installing NETCF V2 SP1 MSI A. Technically no, final result ...Show All

• .NET Development How can I parse an SQL statement into a canonical form ?

  Is there any class available (either in the framework or external and in that case preferably open source) that can be used to test whether two sql statements are equivalent or not (equivalent regarding irrelevant white space, parentheses, and upper/lowercase for keywords) Basically, what I would like to do is to find a class (below called SqlParser)that I can use like this: string sql1 = SqlParser.getSqlStatementInCanonicalForm("SELECT mycol1 FROM mytable where mycol2=1 and mycol3='abc'"); string sql2 = SqlParser.getSqlStatementInCanonicalForm(" sEleCT mycol1 frOM mytable where ( mycol2 = 1 ) and ( mycol3 = 'abc' ) "); NUnit.Framework.Assert.AreEqual(sql1, sql2); / Tomas Paul P C ...Show All

• Visual FoxPro Building as .exe - tray icons doesn't show up

• Visual C++ about timestamp

  Hello everyone, I need to record a set of data items. For each data item, users may modify to some new content. So, I plan to use a timestamp field for each data item to record the time when user modifies data item last time. I am not sure whether I should use a simple integer value (like version information, which increase 1 each time when user modifies data item) Which approach is better What are the advantages and disadvantages of each approach thanks in advance, George Thank you Alex, Alex Farber wrote: Timestamp is better if you want to sort items by modification time. Do you mean using timestamp is always better Actually, I do not have such requirements. regar ...Show All
