• Smart Device Development adding items to listview is very slow

  I have 300 items to add to the listview suing CF 1.0. ListViewItem lstItem = new ListViewItem(finalList[ i ].qNum.Trim()); lstItem.SubItems.Add(finalList[ i ].qDesc.Trim()); lstItem.SubItems.Add(finalList[ i ].qDesc2.Trim()); lstItem.SubItems.Add(finalList[ i ].qDesc3.Trim()); if ((_check || finalList[ i ].alreadyChecked) && listView1.CheckBoxes)        lstItem.Checked = true;           listView1.Items.Add(lstItem);   I clear the listview and then we see the scroll bar getting smaller as the listview is filling up. Anyway to make it faster Thanks   You might try creatin ...Show All

• Visual C++ Program runs slower when compiled with Visual Studio 2005 (in Release with optimization)

  Hey, I have a performance problem with the new Visual Studio 2005. My code (which is a genetic algorithm) is 3 times slower when compiled under Visual Studio 2005 compared to when I was compiling it under Visual Studio 2003. With Visual Studio 2003, it used to run in 3.0639 seconds, and now it runs in 9.0031 seconds. I run both code in Release. I tried every optimization option, and adding the /D_SECURE_SCL=0 compiler command to the project options with only minor differences. Is there any other way to get back to the speed Visual Studio 2003 It is a bit absurd to upgrade to a new compiler and get lesser performances. Thanks a lot!!!

• Windows Forms Compile warnings from adding merge modules

• SQL Server NoLock vs ReadPast

  I have been experiencing deadlock errors with two stored procs that I am using. SP1 is a read query that gets all unprocessed orders (status = 0) SP2 is an insert query that inserts new orders (Status = 0) uses a transaction. I have a multithreaded application and once in a while the read query (SP1) will try to read a new row that has just been inserted but not committed yet hence the deadlock arises. If i use a hint "With(NoLocks)" this will be a dirty read and still read the uncommitted insert from SP2 - is this correct Where as if I use hint "With(ReadPast)" this will now only read committed rows and hence the deadlock should not arise - it will not read any uncommitted rows - Correct So I think th ...Show All

The client application can easily consume a webservice since webservices could return dataset objects... cheers, Paul June A. Domag ...Show All

• Visual Basic Help... Can't get .vb file to open in Designer mode

  Alright, let me describe the problem I'm having: I was working on a program - a world switcher (yes, legal) for the game RuneScape, for my help site - and got quite far in. I had saved a few times along the road... And then Visual Basic crashed. No, the files were not corrupted, they had been saved several minutes before this. Anyway, I boot up Visual Basic (Express Edition) and click File -> Open File -> myscape.vb ^^ Can't get the design editor to come up. I see all the code that appears when you double-click an icon in the Design Editor... And yet... It doesn't load properly. In the same folder, I also have: myscape.Designer.vb (No changes made by me) myscape (.NET resource file [no changes made by me]) ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA talk in College

  Hi, This post is mostly directed at Microsoft people, but feel free to respond anyway. I'm going to give a talk about game-development next week at our local college for the second time this year. This time I would like to go a little more indepth in XNA and it's possibilities. My question is, is it possible to get some nice XNA material from Microsoft for this Sheets, movies, demos, etc. I know there are some pretty nice sheets with the for example the layout of XNA, as I've seen them at the GDC in Leipzig last year. Thanks in advance! Maurice Sibrandi You also may want to get in touch with Russ Fustino who has been doing a lot of the "Beginning XNA" presentations for Microsoft. ...Show All

• Smart Device Development Can we use PCI Board with Device Emulator(Similar to CEPC)

  Hi, We have a companion chip board(containing Display,RAM,Camera,Hardware chip etc), which can connect to PCI slot of PC. Earlier in CEPC, we use this setup to develop our companion chip hardware drivers(e.g. display,camera,sdhc etc). It means x86 used as host cpu and harware chip as a companion processor. Since from AKU3.1 onwards, its not suggestible to use CEPC for devlopment, we want to use device emulator for the same purpose.It means ARMV4I will be use as host cpu and harware chip as a companion processor. 1 ) First of all I want to know whether this is possible or not 2) If its possible, then which of sysgen setting will be diffrent from the default case.

• Visual FoxPro Font Size Randomly Changing

  Has anyone experienced a problem in a FoxPro 9 application, where the font size of some controls on a form change It could happen going from form1 to form2, or form3 to form2.  The size changes from 9 to 8, 12, or 18. There doesn't seem to be a pattern, and it could happen today day and not happen for several days later. >> I've thought that it might be that, but with the number of users experienceing the problem I don't believe that would be the problem. I would also think if it was the windows font problem then other applications would have the same problem. As I said earlier in this thread, I doubt very much if VFP is auto-generating random font changes. This is the first time in almost 20 years worki ...Show All
