RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome How can I add control's icon on VS IDE's toolbox Libra25-Jul-05 0:05 Libra 25-Jul-05 0:05  I develop a dialog inherit ..Form and then make it to a DLL file. but I can not add this dialog's icon in toolbox, it said had none componets needed to add on the toolbox. I change this class inherit in ..Controls or in System.ComponentModel then it can add a icon which like a gear wheel, but if it inherit by ..Form then it can't work. My target want to build a dialog component like ..PrintDialog that it can show icon on toolbox and can drag to nonvisible component area. I wonder if ..Form's designer prevent the inherit form component add as a control..., but why ..PrintDialog which inherit by ..Form can? === Game is power! === Re: How can I add control's icon on VS IDE's toolbox LongRange.Shooter25-Jul-05 10:02 LongRange.Shooter 25-Jul-05 10:02  It is handled in the class attributes. [ToolboxItem(true), ToolboxBitmap(typeof(myControl), "myControl.bmp")] public class myControl:UserControl You need to have Default Namespace set to the namespace of your control and you have to have the bitmap in the root of your solution.

Re: How can I add control's icon on VS IDE's toolbox Libra26-Jul-05 0:21 Libra 26-Jul-05 0:21  At first, thanks for you help. I do what you said, it works well, the icon that can be showed on toolbox. But when I drag the icon to the designer area and then can not see it. it can not shows on 'nonvisible component area'(a bar at the bottom of designer), say nothing of 'visible area'. (But funny is it can be selected the component at the Property card ) === Game is power! === Re: How can I add control's icon on VS IDE's toolbox Libra26-Jul-05 16:30 Libra 26-Jul-05 16:30  Haha, I found it myself.;) Make this class attributes will be ok.

I have to create a .NET app that implements our existing DHTML tools. I use the AxWebBrowser to host them, but now comes the problem. Our original app used to talk to some ASP page via XMLHttp (javascript). In the .NET app the javascript in the webbrowser has to talk to my .NET methods. To put it simple: how can the contents of an AxWebBrowser talk to its hosting environment (my .NET app)? I thought of creating an COM object, which I put on my HTML pages, and invoke their methods from the HTML, and the COM object would then throw events that will be caught by .NET (using the mshtml to locate the object). But obviously this is not very neat, and make everything go asynchronous. Another option would be using MsHtmHstInterop, explained somewhere on the code project, but I didn't find more articles about it, so I wonder if it is good enough. Thank you for your help.

When the user clicks on a link/button that takes them to another page, an event is triggered "BeforeNavigate2". I format my URL in the webpage according to my parsing format so i can determine if i need to display it using my application forms or through standard HTML viewer. //***** this is the code in my HTMLViewer control which wraps the IE COM control private void AxWebBrowser1_BeforeNavigate2(object sender, DWebBrowserEvents2_BeforeNavigate2Event e) { NavigationInfo ni = NavigationInfo.ParseURL((string)e.uRL); if (ni.IsInternalURL) // { if (NavigationRequested!=null) { NavigationRequested(ni); //raise event } e.cancel = true; } } '******* code in the form which uses the HTMLViewer control and handles the NavigationRequested event private void HtmlViewerCC1_NavigationRequested(HTMLViewerCC.NavigationInfo ni) { Form f = null; switch (ni.ObjectType) { case ObjectTypeCodes.Users: f = new frmUsers(ni.Value); break; case ObjectTypeCodes.Company: f = new frmCompany(ni.Value); break; default: throw new Exception("Not supported"); } f.ShowDialog(); } DCOM sangtao24-Jul-05 23:10 sangtao 24-Jul-05 23:10  Hi all!

Thanks very much! sangtao COM registration and PInvoke gxdata24-Jul-05 22:59 gxdata 24-Jul-05 22:59  I'm having a problem understanding how to register Windows Shell extensions, specifically for PropertySheet extensions and their handlers. I am not too happy with the way it's done here - http://www.codeproject.com/cs/miscctrl/HadiPropertySheet.asp - "Property Sheet Shell Extension in C#" I think this can be done with PInvoke, rather than RegAsm.exe. Obviosuly, the batch file for putting the keys and appropriate GUID into the registry can be done in code (and would be less error-prone). Also, can anyone direct me to an example in VB.NET for the same sort of thing that's described in that article? That is, a property sheet extension example. Thanks for any help - Ian Thomas Crystal Reports -> Sorting Data Zishan Haider24-Jul-05 22:10 Zishan Haider 24-Jul-05 22:10  Hello, I am a newbie in Crystal Reports. I need to sort the report based on the column that the user sets in the windows form. How do I do it? I've been googling with virtually no help Thanks in advance. Regards, Zishan Re: Crystal Reports -&gt; Sorting Data Yulianto.24-Jul-05 22:43 Yulianto. 24-Jul-05 22:43  I don't think you can tell the report to sort from your code. One solution is to build many report, one for each column which the user can choose. <italic>Work hard, Work effectively. Re: Crystal Reports -&gt; Sorting Data Zishan Haider24-Jul-05 22:57 Zishan Haider 24-Jul-05 22:57  Thanks for replying. There should be a way. I got a sample code, Its in VB, I tried it in C# but for some reason.. it doesn't work for me. Here's the code : Dim crSortDirection As SortDirection Dim crDatabaseFieldDefinition As DatabaseFieldDefinition Dim crSortField As SortField Dim iSortItem As Integer = 0 crDatabaseFieldDefinition = crReportDocument.Database.Tables(0).Fields(6) crSortField = crReportDocument.DataDefinition.SortFields(6) crSortField.Field = crDatabaseFieldDefinition 'crSortField.SortDirection = SortDirection.AscendingOrder crSortField.SortDirection = SortDirection.DescendingOrder There is no explanation available for the code. No matter what SortField I pass, it keeps throughing CrystalDecisions.CrystalReports.Engine.InvalidArgumentException -> Invalid SortNumber. Can you explain now? Zishan Re: Crystal Reports -&gt; Sorting Data Rob Graham25-Jul-05 2:56 Rob Graham 25-Jul-05 2:56  Ar you sure your C# syntax is correct? In case you are passing a groupfield instead of a databaseField, use the base class: FieldDef = new FieldDefinition (); FieldDef = Report.Database.Tables [0].Fields [6]; Report.DataDefinition.SortFields [0].Field = FieldDef; Absolute faith corrupts as absolutely as absolute power Eric Hoffer All that is necessary for the triumph of evil is that good men do nothing. Edmund Burke Re: Crystal Reports -&gt; Sorting Data Anonymous25-Jul-05 20:45 Anonymous 25-Jul-05 20:45  Same problem Can I make a stored procedure and pass the "order by" parameter? I think that's going to solve the problem. I am using Crystal Reports that comes with the VS.net 2003. How can I call a stored procedure and pass the parameter? Many thanks. Zishan Re: Crystal Reports -&gt; Sorting Data Craig G Fraser25-Jul-05 21:40 Craig G Fraser 25-Jul-05 21:40  I have used crystal in a few of my apps and the way I handle sorting is by sorting the datasource ( i use a dataset as the source ). So based on a selected column by the user, sort the dataset into the desired order or load the data into the dataset by specifying the SORT keyword in the sql statement when retrieving the data. Hope this helps. Craigo Re: Crystal Reports -&gt; Sorting Data Zishan Haider25-Jul-05 22:27 Zishan Haider 25-Jul-05 22:27  Craigo, I tried what you told me.. it is picking up all the records in the table without any order. I commented the t.SetDataSource line.. still the same result. I am not sure if this is the right way to define Data Source. Here is my code : Report2 t = new Report2(); string Query = "Select * from Orders order by ordertype asc"; SqlComm.CommandText = Query; SqlDataAdapter da = new SqlDataAdapter(SqlComm); DataSet data = new DataSet(); da.Fill(data); t.SetDataSource(data); this.Viewer.ReportSource = t; Zishan Re: Crystal Reports -&gt; Sorting Data Craig G Fraser25-Jul-05 22:43 Craig G Fraser 25-Jul-05 22:43  2 Things you can try. 1) change the code where you set the datasource to : t.SetDataSource(data.Tables[0]) 2) Add the line: t.EnableSaveDataWithReport=false; after you have set the datasource Let me know how you get on Craigo Re: Crystal Reports -&gt; Sorting Data Zishan Haider25-Jul-05 23:07 Zishan Haider 25-Jul-05 23:07  Hey Craig, thanks a lot man.. you saved my life.. although I don't have t.EnableSaveDataWithReport property but the problem is now solved..
