SQL Server maximum users logged in sql express
we're planning to use sql express as our database server in our office. the database will consist of accounting, purchasing, marketing, sales, inventory, production and hrd tables. 80-100 users will use the system simultaneously in adding, editing, deleting, reports. i need some advice on the following: 1. maximum users that can log on to the database simultaneously 2. maximum size of the database tnx Hi, the maximum number of users will be most likely limited by hardware ressources not by a logical threshold, its around 32k users. maximum size of each database is 4GB.

.NET Development Table does not appear to update after UPDATE statement

Windows Forms bindingsource.addnew and .haschanges
I have a form that loads in a new state, but the user may decide not to add a new row, but will want to edit an existing row. When the form opens with no ID for the form, my code calls: BindingSource.AddNew() Even if no changes are made to the form, calling: DirectCast (BindingSource.DataSource, DataSet).HasChanges() This will always come up as having changed. Is there any way to find if there have actually been any changes after AddNew is called. Mark Dahl Gavin, Thank you for the response. I really appreciate it. However, the following code is run when the form loads: '// Header refresh If FormHelper.DBInt(FormID) > 0 Then EmployeeTableAdapter.Fill( Me .Emplo ...Show All
Microsoft ISV Community Center Forums append excel data to text file
I am going to have multiple excel files feeding one text file (each file will only append one line of data). Any suggestions Thanks The data in your XL file can be in a cell, or an autoshape, or a chart etc. Because you did not specify where that data lives, I assume you have it in cells. To get the text from a cell using VBA you write something like this: ActiveWorkbook.Sheets(idxSheet).Cells(idxRow,idxColumn).Text ,where idxSheet - index of the sheet you have the data on idxRow - index of the Row idxColumn - index of the Column Another option is not to use VBA at all: if indeed the data you have is only on Excel cells, you can add the excel document as an ODBC provider and connect to it as to a regular database, ...Show All
.NET Development .NET 3.0 breaks printing subsystem on non-english XP / VERY ugly effects
After installing .NET 3.0 on non-english XP two things will break parts of the printing subsystem: - parts of XPS are installed in English, i.e. unidrv.dll / unidrvui.dll / unires.dll etc. are non-localized As a consequence Printing dialogs of all unidrv.dll-based printer drivers show mixed output localized/english. And the default Input Tray is set to 'Automatically Select' even on a german XP which leads to strange effects like printers suddenly asking for paper in the Manual Tray instead of using Tray 1 as usual. - unidrv.dll / unidrvui.dll / unires.dll etc. are Windows Vista DLLs and incompatible with many XP Printer Drivers As a consequence some printer drivers will print all pages of multi-page documents on one sheet, all ...Show All

SQL Server DTS/SSIS too many tables warning and subsequent error
I need to bring over a large number of tables' records (200+ tables) with the Import/Export Wizard. The tables are being imported from MS Access. A separate script run previously will create the tables, so the DTS wizard is only to bring over the data from the Access tables into the empty SQL ones. First, I get the warning that indicates "a large number of tables are selected for copying, and the wizard may not be able to copy all the tables in a session. Select no to go back and unselect some tables, or select Yes to attempt to copy all the currently selected tables at one time". Well, I proceed with the DTS and it tries to validate and takes a fair bit, but then it errors indicating: "Error 0xc0202009: {2F0FABA0-5F4B-4 ...Show All
Visual C++ Migrating to VC2005
I am trying to migrate my C++ codes written using VC6.0 to VC2005 but having some problems. These seem very trivial, but I am just unable to get around it.

Visual Studio Express Editions toolTip
Any example on how to use the tooltip function you may need to be more descriptive but here is a simple example on how a tooltip is used: Dim theToolTip as new ToolTip() theToolTip.SetToolTip( Control , Text ) so if I wanted a tool tip on a textbox theToolTip.SetToolTip(Me.theTextBox, "This is a tool tip!" ) you could also say, show this tool tip when the mouse hovers of that textbox, by implementing the TextBox's MouseHover event, then place the code above in there, so when you hover over the control, it should show it. http://msdn2.microsoft.com/en-us/library/system.windows.forms.tooltip.aspx Does this help ...Show All
