• SQL Server Snapshot Replication vs. Copy Objects DTS

  I have an application that I wrote that is running in the local office and a remote office. The two offices are connected via a hardware VPN. The connection in the remote office is wireless and can give speeds down to 40kbps. Each office is running MSDE 2000 and runs off of a separate database with a different name. I would like to have the database from the remote office available in the local office. It doesn't have to be completely current. A 24-hour delay would be fine. Since Transaction replication is not available in MSDE, I can use either Merge or Snapshot. Since the local office wants to allow folks to access the remote office's database without allowing them to affect the remote database (query purposes only), it seems that Sna ...Show All

• Windows Forms Simple binding of control property to class property question...

  I've got an issue that seems simple enough. I'd like to bind the "Visible" property of a label with the "IsSorted" property of a BindingSource object to give the user a visual indication of when a list is sorted. lbl.Visible.DataBindings.Add("Visible", mSource, "IsSorted") That should do the trick as far as I can tell (assuming mSource is a populated obj and it is), but I get the Argument exception and it says "Cannot bind to the property or column IsSorted on the DataSource. Parameter name: dataMember" What gives Any ideas Thanks in advance. You guys are no help at all! Kidding... For those interested, here's the answer: I finally found mention this morni ...Show All

• SQL Server SQL CE 3.0 (Mobile 2005) Max DB Size Question

  Hi everyone, What are the consequences for just setting the Max DB Size to 4GB and letting it go at that Is the MAX Size any arbitrary value I want or must it be close to what the actual database is expected to be Also, why did they default to 128MB Wouldn't it have been better to set it to a larger value Thanks Dorothy Hi, I found that there is a difference in the way sqlce allocate memory for different max database size setting. In my device which is running Windows CE 5.0 with only 4 MB free storage space and 8 MB free program memory, I can not set the max db size setting larger than 512, if I set it to larger value the sqlce engine will throw a native exception -2147024882 with no ...Show All

• SQL Server Any clues why DTExec.exe is slower than Business Intelligence studio(SSIS Shell)?

  All, I have a simple package in SSIS that reads approx 2.5million rows from SQL2k5 source and exports it into 4 Foxpro files. The way I do it is as below 1) use and oledb source to read data from SQL2k5 2) use a conditional split component to divide the source into 4 streams ( I do a recId % 4 = 0, 1, 2, 3 to give 4 streams) 3) use an OLEDB destination to export to the 4 prexisting foxpro tables. This thing runs amazingly fast when I run(F5) it from Business Inteligence studio, but it is atleast 10 times slower when rightclick the package and execute using dtexec.exe I can't figure out why! any clues I would elimiate the 64 bit /32 bit problems because export to foxpro only works in 32 bit mode and my package has been configur ...Show All

• Visual Basic Avoiding duplicate reading of image files

  If an application needs to display a JPEG, TIFF, or other image file on disk it uses something like picBox1.Image = System.Drawing.Image.FromFile(myFile) to read the file. If it needs to retrieve image data like Exif or IPTC fields from the same file it uses ByteArray1 = My.Computer.FileSystem.ReadAllBytes(myFile) to store the data in a byte array. Is there a way to eliminate that time-consuming duplication I don't see any examples in the help file of loading an image from a byte array, or of building a byte array from an image. That pointer gives me a "cannot display" in both IE7 and VS; not sure why. But the MemoryStream concept is a new one for me, and may be just what I was looking ...Show All

• SQL Server vb.net and reportingservices setparameters takes a long time

  I have a vb.net application using report services that has a big delay when I set the parameters with which to call the report. I create a new reporting.reportviewer. I set the ReportServerCredentials.NetworkCredentials, ReportServerUrl, ProcessingModem, ReportPath and everything is fine. When I call SetParameters with a very simple parameter set, I get a delay of between 0.5 and 2.5 seconds. That delay is very noticible to the users.
