• Visual Studio Subreport, business objects, VB, Local report

  I've been looking at the Orders example (from GotReportViewer.com) and some of the other examples, trying to figure out how to get a subreport to work using business objects. I seem to have it all correct but I get: Error Subreport could not be shown. I'm using AddHandler for the LocalReport.SubReportProcessing call and it seems to work because the Subroutine gets called for each master record in the report. I have the parameter to tie the main report to the subreport; my key field is text instead of the example's integer but that should be ok. My datasource for the subreport is a List (of ) detail records. Is there any way to find out just ...Show All

• Visual Basic Is there any free syntax highlighting componet for .Net Forms

  Hi, I'm just wondering if there is any free syntax highlighting componet for .Net VB Forms. I googled but didnt find any except Actipro's component for web pages. Any help is appreciated Thanks Vijay S my approach was almost entirely RegEx based with the goal of output to XHTML.  The link above works for me, but here is some of the code in case you are experiencing problems with the link. this is the converter code -- there seems to be an issue with memory remaining allocated which is why the explicit GC calls are being done.

  Is the Merge tool that TFS uses available to run standalone The reason being, I have a set of files that may be different to what is checked in and I want to merge my changes with the latest version from TFS SCC. Thanks Graham Graham, did you check out the files that you wish to merge   If so you'll get conflicts when you run get or check in if the files on the server are different that you have checked out.

• Windows Forms Pressing <Esc> will trigger validation of contents of UI-element

  Hi, In our forms we have the problem that after entering invalid input in a textbox, pressing the <Esc> key will trigger the validation of the textbox contents. In the same situation, pressing the CancelButton of the form will NOT trigger the validation. We thought the behaviour would be the same for both situations, but it is not. How to achieve that both situations behave the same. Note: it not only happens for the textbox but for all input controls. Note: we checked all controls for the setting of CausesValidation (for the CancelButton this is FALSE, for the form this is FALSE). regards, Henk That is because ...Show All
