• Visual Studio ReportDocument.Load operation slow when moving to production server - suggestions?

  Hi. I am building an asp.net web application that uses crystal reports (the bundled version) in VS 2005. The reports are developed using my development machines at the office. The logon information and parameter data are supplied dynamically to the reports by the asp.net application. I have noticed that the reports load slowly on the production machine where the web application is run. I tracked down the problem to the row where I load the requested report crReport.Load ( pathToReportAndReportName ); This load-operation takes 1 second on my development machine and about 20 seconds on the production server. I then set up another database machine at the office and set the reports to get the data from it. This alone did not slow d ...Show All

• Windows Forms DataGridView getting index of the entering row

  I have a DataGridView with say for e.g. two rows. User currently have selected the row 1 (index 0)..when they select the next row what event should I use to find the next row's index (row 2 index which should be 1)  I tried using RowEnter event of the datagridview along with MyDataGridView.CurrentRow.Index which is giving me the index of the first row not the entering  second row. To find the next row *when* a user selects a row you could try, assuming your DataGridView is called dataGridView1: if (dataGridView1.SelectedRows[0].Index + 1 < dataGridView1.Rows.Count) { int nextRow = dataGridView1.SelectedRows[0].Index + 1; } It might be a cheap styl ...Show All

• .NET Development insert record into SQLServer

  This is probably very trivial... my problem is that I want to find out the best way to take the values from two textboxes and insert them into an existing table in a SQL server 2005 database. My initial plan was to do this using an SQL insert query triggered by a click on a button but can not find out how to bind the VB textbox variables to the appropriate value expression in the insert query. The on-line help provided with visual studio proposes multiple quite extensive approaches, but they seem to be over-elaborate considering the elegance otherwise provided by the environment. Looking forward to your advice on this! Erik Can you fix that code for me, im really new to this and i am trying t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How can I add characters/Character Creation to my game??

  I finished making my background, so how can I make a screen that allows players to Develop Characters (ex. choose the color of their character, what it looks like, etc.) And, also, how could I Transition them from the character select to the actual game I have recently started XNA, and dont know how do to do very much of it, so help will be much appreciated! Thanks o.O If you're talking 2D, you can do things by mix and matching what textures you pull from an image sheet to make the main character. If you make a bunch of "hair" images, as long as they all fit on the similar type head and are transparent, you can just cycle through them as a user. Then once you know what the character ...Show All

• Visual Basic strange behaviour

  Hi guys, I am definitely a newbiew to .Net, and am having a problem that I cannot seem to get around. I have a single Windows form app that loads several (probably about 10) datatables into a dataset. The dataset is defined as a public. Eventually the data is summarized into a datatable that is displayed into a datagrid. At first I could not get the double-click to work, and eventually tried to add a context menu control to capture a right click. Once I got things wired up, when the menuitem click event fired, I wanted to create a dataview from one of the datatables in the dataset and filter accordingly. To my surprise, the dataset variable has a value of nothing while in the click event. I then figured out how to capture a double ...Show All

• Microsoft ISV Community Center Forums Range

  Hello, I'm developing a macro to do some calculations on a worksheet, but I always get a problem when I pass a Range as an argument to my function. I need to pass the range as argument. For example: Sub Name() Dim A As Range Set A = Worksheets("Sheet1").Range("CD4") MyFunction(A) End Sub Function MyFunction (ValueDoRange As Range) etc... End Function Thanks It is because you are trying to treat an array as a range. In the function InterpMatriz_lin you have declared U as an array, Dim U(1 To 100) You then pass U to the function InterpVector like this, InterpMatriz_lin = InterpVector(U, B, y) '"This is the problem" The signature of the ...Show All

• Windows Forms .Net Crystal Reports + Dataset + Logon Failure Error

  Dear All, I am facing following Problem. Please help I'm developing an VB.NET Windows Forms application that uses CR for VS.NET (original version shipped with VS.NET 2003 ). My reports get their data from ADO.NET Datasets that are pre-populated by other modules of the application. What I need to do is to use these datasets as the datasources of my reports. Fine, I know how to do that and it works perfectly on my development box. The trouble comes when I deploy the application on the client machine. I created a installation project in VS.NET, added the required CR merge modules, added the keycode, and it seems to install everything fine. But when it tries to show the reports in the CrystalReportViewer control, it ...Show All

• Visual Studio Express Editions MenuComboBox not closing

  I have a menucombobox in one of my menutool strips. When I select a item from this combobox, How can i get the menu to close At the moment it remains open until I click somewhere else on the form. Hi Bigmo, Is the MenuComboBox on the top level of the MenuStrip or is it on the dropdown protion of a menu If it is on the top level, it should close automatically. If it is on the dropdown then I believe this behavior is by design - you don't normally see a ComboBox on a dropdown menu. If selecting an item in the combobox needs to execute a command, you may think about moving it to the top level, or you might rethink your user interface altogether - do you really need a ComboBox there If you could tell ...Show All
