• Visual Studio Printing CR report with ReportDocument class

  I am using VS 2005 and have a VB 2005 app containing an embedded CR report and using a CR viewer. I want to print a report giving the user print options via a PrintDialog box and be able to run code if the user chooses to print or cancels the printing. I have not found a way to do this with the dialog box that appears when crViewer.PrintReport method is used. My next options is to code a button that opens a PrintDialog box and uses the ReportDocument class to print the report. Documentation tells me a class is created that inherits from ReportDocument when an embedded report is created, so I am using that. My report is CaseHistory.rpt and the class is Public Class CaseHistory. Here is the code I am trying to use: Dim rpt2 As CaseH ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 1.) Lock/Unlock vs. SetData/GetData and 2.) predefined vertex formats

  Two points spring currently to my mind. Is there any reason besides simplicity not to use the common Lock/Unlock mechanics I would prefer the addition of this to the API. GetData/SetData canthe simply be mapped onto this. I have a large terrain, that I tesselate into the locked buffer directly... With this new scheme I have to build a temporary array and then copy over via SetData, same with textures. On the other hand, if we have to live with this, why do we have the managed pool anymore, kind of pointless! The other thing are the predefined vertex formats... Any reason to not expose the members directly and use setters and getters instead I don't see the point here too, this just forces us to create one intermediate result and copy oper ...Show All

• Visual C# How to get control properties?

  Hi, I would like to know how get all the controls in a panel, I use the panel1.Controls.GetEnumerator(); but then I can't get the attributes (name, location, text) of that control. Is there any way that I can put all the Controls in a list/array wherein I can access the control's properties   Just one note to Andrej's post. You should use as keyword instead of is. That way you will have only one cast per control instead of two. Source will be like: TextBox textControl = control as TextBox; if (textControl != null) {    //here you can use textControl } ...Show All

• Visual Studio 2008 (Pre-release) WCF, MSMQ persistence problem

  Hi I'm writing some code with netMsmqBinding in WCF. One of the goals is to persist every message in the receiver's queue until the receiver (either implicitly or explicitly) finishes dealing with the incoming message. When not using transactional messaging, the incoming message is removed from the queue before the service host is notified of it's arrival. Transactional messaging achieves the required persistence, but it's prohibitively slow (my system, which has 7 processes emptying out there own queue, is 4 times slower when those queues are transactional). Is there another approach i can take Duplicate messages don't matter too much, as long as each message is read and dealt with at least once. Thanks! ...Show All

• SQL Server Poor quality on exported charts - why?

  When I view my chart reports via the ReportViewer control, they render as a .png and the text appears crisp and clear. If I then select TIFF as the format and export the chart, the resulting image has two differences: 1) The height of the .tif is 1 pixel larger than the .png (this is not a big problem for me) 2) More importantly, the .tif appears blurry! I am actually using ReportExecutionService (ReportExecution2005) to render the charts but the result is the same as exporting from the ReportViewer control. I have tried various combinations of DeviceInfo (altering DpiX and DpiY and PageWidth and PageHeight) but there seems to be no way to produce the same image that is shown in the ReportViewer control. Any ideas anybody ...Show All

• .NET Development Dealing with large changing strings

  Hi, I am using stringbuilder class to deal with large strings. I have a StringBuilder object which gets data from the network. From time to time (every time a packet arrives), I have to check if the StringBuilder contains some data pattern to perform some business logic. The problem is that this code does not scale - after receiving around 50-60MBytes of data the application starts consuming 1Gigabyte of memory and dies with out of memory exception. The logic is very simple: StringBuilder b = new StringBuilder() while (true) { string x= getdatafromnetwork(); b.Append(x); string datasofar = b.ToString(); check if datasofar contains a pattern. If yes, quit the loop. } The problem is that StringBuilder.To ...Show All
