    - CRYSTAL REPORTS VIEWER - URL REMOTING HELLO THERE. I have a problem with a crystal report. I hope you can help me out. I have a windows forms application that is running on a server and is invoked from client computers by using url remoting (the application assembly has been given execution permissions by using the Microsoft .NET Framework 1.1 Configuration tool). The application gets data from a database by mids of a web service. When it comes to generate a crystal report, if the application is launched locally (on the server machine) the crystal reports are loaded correctly, but if the application is launched from a client computer by the url (e.g. "http://192.168.10.11/MyApp.exe"), then one of the crystal reports(not all of them) shows a pop up dialog box to enter database login information such as "user name", "password", "server name" and "database name". I was debugging it, and it comes out that there is no connectivity with the crystal report object that feeds the crystal report viewer. This problem ONLY comes out when the application is launched remotely. I hope you can help me out pals. I think the problem is due to the report viewer..this object seems to love working locally... Any suggestions? Tag: report solution suggestion Tag: 91231

    - Drag & Drop Folder Name from Windows Explorer to a Windows Form The title says it all. What I would like to be able to do is drag a folder from Windows explorer on to a form and just capture the full path and folder name. Failing the fully qualified path, I absolutely need the folder name (which I could find by iterating throught the folder structure) All the doc I can find refers to dropping the data associated with an object - and the Help topic "Performing Drag-and-Drop Operations in Windows Forms" Has not done much for me. Am I missing something here? Is what I want to do even possible? Tag: report solution suggestion Tag: 91227

    - Permission Exception for Strong Name membership but not Zone I have a WinForm control hosted in IE. I've set up a JavaScript event handler to close the window if a button in the control is clicked. I have a permission set which grants my assembly execute permission for unmanaged assemblies and I have created a Machine Code Group which uses the permissions. The problem is that if I set the membership condition on the code group to Strong Name I get a PermissionException when executing the JavaScript event handler, but if I set the permission to Zone and then set the Zone to Local Intranet the code executes and does not throw the exception. Any ideas as to why that would be? Shane Tag: report solution suggestion Tag: 91215

    - Date comparison in rowfilters for dataviews feeding datagrids I have a datagrid attached to a dataview attached to an SQL Server table that uses datetime columns among other types. The user gets to filter on various things in the table including the datetime columns. I'd like to be able to use the rowfilter capability of the dataview. However, I've run into t he well documented problem of the fact that datetime columns include a time and therefore can't exactly match a date. As near as I can tell there is no provision for a calling functions in rowfilters. Is that correct???? Thus as near as can tell, if you want to exactly match column dat for date 1/1/2005 regardless of the time you have to write dat>= '1/1/2005' and dat<'1/2/2005'. Is this correct???? Is there any better solution???? -- Regards, Al Christoph Senior Consultant and Proprietor Three Bears Software, LLC just right software @ just right prices @3bears.biz Tag: report solution suggestion Tag: 91214

    - Instanciate reflected form without constructor... I need to scan a directory full of .net assemblies and list all Form subclasses found in a grid. This part is easy using reflection. I then need to allow the user to double click and modally display the form. Obviously I wouldn't expect anything to actually work; I just want it to be visible. Just like what Visual Studio does when you design a form. Unfortunately I cannot guarantee that the forms have default parameter-less constructors and even if they did, I cannot guarantee that those constructors could be successfully invoked (could have some static dependencies, etc). So I can't simply instantiate them. Since the forms have been built using Visual Studio, they should all have an InitializeComponent method. What I really need to do is only invoke this. Is there an easy way to do this? If it was possible to create an AssemblyBuilder from an already compiled Assembly, then I could just add the parameter-less constructor (or remove the IL from an existing one) and disassociate all the event handlers. I'm thinking that I need to create a new in-memory form subclass and dynamically transfer the InitializeComponent IL from one to the other. How hard would this be? I know that the assemblies have not been obfuscated. Nathan Tag: report solution suggestion Tag: 91197

    - Controls in a panel are shown in incorrect order Hi, I've got a graphical application where some child controls are rendered inside a panel. This controls are user drawn and are transparent. The transparency works OK, I've been using Bob Powell tricks (http://www.bobpowell.net/transcontrols.htm). However, there's a big problem: child controls are drawn BACKWARDS its order. For example, if I add two controls and then I execute BringToFront() in one of them, it draws behind the other, but when I click, the mouse events are fired on it (so it is really in front). Below is the most important code from the control, the panel where controls are added is just a simple Panel with a transparent background, I hope if someone could help me. Thanks in advance. === THE CODE === public partial class DrawViewer : UserControl { public DrawViewer() { InitializeComponent(); Initialize(); this.MouseDown += new MouseEventHandler(DrawViewer_MouseDown); this.MouseUp += new MouseEventHandler(DrawViewer_MouseUp); this.MouseMove += new MouseEventHandler(DrawViewer_MouseMove); } #region This allows to drag the control bool dragging = false; int mousex, mousey; void DrawViewer_MouseUp(object sender, MouseEventArgs e) { if (dragging) { dragging = false; mousex = mousey = 0; } } void DrawViewer_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { if (dragging) { Point MPosition = (ScrollableControl)this.Parent).PointToClient(MousePosition); MPosition.Offset(mousex, mousey); this.Location = MPosition; this.InvalidateEx(); } } else dragging = false; } void DrawViewer_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { dragging = true; Point MPosition = ((ScrollableControl)this.Parent).PointToClient(MousePosition); mousex = -(MPosition.X - Location.X); mousey = -(MPosition.Y - Location.Y); } } #endregion protected override OnPaint (PaintEventArgs e) { // This just paints } #region This is for supporting transparency protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ExStyle |= 0x20; return cp; } } protected override void OnPaintBackground(PaintEventArgs pevent) { // Nothing } protected override void OnMove(EventArgs e) { InvalidateEx(); } protected override void OnResize(EventArgs e) { InvalidateEx(); } public void InvalidateEx() { try { if (Parent != null) return; Rectangle rc = new Rectangle(this.Location, this.Size); Parent.Invalidate(rc, true); } catch { } } public void Initialize() { SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.SupportsTransparentBackColor, true); // More internal initialization } public override void Refresh() { base.Refresh(); InvalidateEx(); } #endregion Tag: report solution suggestion Tag: 91124

    - Datagrid - Windows Forms - Can't see what is in the grid The grid has rows but you can't see them. You see the grid but all rows are completly blue but when you click on a column in the row you see the text that is in the row. I sprinkled datagrid.refresh and application.doevents around but it did not help. It seems like it's memory or video card related. An intersting note is that when this happens when I am on my Dell workstation at the office but when I vpn to that Dell workstation from home I do not get the error.

    - datagridTableStyle question I have a datagridComboBoxColumn in my datagrid. I was wondering if there is any way to generate an event for the the Column that would trigger a routine that in turn populates couple of TextBoxColumns in the same datagrid. The Datagrid uses DataGridTableStyle for it's mapping and customization. Tag: report solution suggestion Tag: 91114

    - Embed PDF in Winforms Good Day, Gentlemen: I've been tasked with creating a screen that allows users to double-click items from list of filenames. Each filename in the list corresponds to a PDF file. On double-click, the corresponding PDF file should be displayed. The catch is that the PDF viewer needs to be embedded *inside* my WinForms app, as opposed to being externally launched. The user needs to be able to scroll through the PDF and optionally print it. Does anyone know how to do this? I don't mind purchasing a 3rd party component, so long as it's a fully managed .NET component. Help a brother out, Jules Tag: report solution suggestion Tag: 91111

    - Access 2002 like Combobox in .NET 2003 We are trying to rebuild a current Access 2002 (XP) mdb program to VB.NET with a SQL database - we are having problems with a suitable combobox. There are many threads discussing multiple column comboboxes in .NET. We are having success with the multiple columns similar to the combobox from Access 2002 (XP). Our biggest problem is speed. In a form in Access 2002, our combobox is able to load data in a table in separate Access database file in a fraction of a second. This table is already sorted in the proper order, and has 65,000 records (almost the limit of items in the Access combobox). For this speed test, the table consists of one field. The records are just integers counting from 1 to 65,000. The Access combobox is filled with data by setting the combobox.RowSource property to equal a SQL Select Statement: SELECT field1 FROM table1 IN 'c:\pathto\database.mde" We tried to do a similar test using the VB.NET combobox with Microsoft SQL Desktop Edition 2000. Same table as above. We tried several approaches including binding to a DataSet, binding to an array (filled the array with DataReader), and using the combobox.Items.AddRange(array). The best result we could get with the 65,000 records was to use a DataReader to fill an Array, then use the combobox.item.addrange - but this was approx. 7 seconds - still slow compared to Access, and too slow for our purpose. This 7 second was during the AddRange step, not during the looping through the DataReader to fill the Array. Filling the Array was very quick. All of our tests indicate the the slow down is getting the information into the combobox, not get the data from the database. Is there a Microsoft suggestion get a large list of data into the combobox quickly the way Access could do it? Is there a third party combobox that can work in VB.NET and load the data quickly, preferable with multiple columns? Any other suggestions? VB.NET solutions are preferable, but we do have VS.NET Pro 2003, so we can support other languages as well. Thank you for all that took the time to read this long message. PS - it was suggested that 65,000 records are too many to be showing to a user. The purpose of this list to allow the patient to select a client/patient from a large and growing list in a medical lab setting. Medical labs are always receiving new patients, and usually only see a patients once or twice. They do need to keep the patient active in case the patient returns.

    - Exception in Timer.Tick/JIT debugging Hi, I posted the following in the m.p.vsnet.debugging group, but it turned out to be a Framework (Timer) problem: <quote> I'm using VB 2003 (VS.Net 2003 IDE) and a WindowsForms project. How can I get *completely* rid of the "Jit-Debugging" dialog box? The one containing the 3 buttons "Details", "continue", "quit" (or "close"; I don't know, I have the German version). I do *not* want to see the dialog when debugging in the IDE. Instead, I'd like the IDE to handle the exception and stop at the line throwing the error. - In the options, Jit-Debugging is enabled for all three items (CLR, native, script). - In machine.config, JitDebugging is enabled. - In menu Debug -> exceptions: Option "CLR exceptions" is set to "jump into debugger" if the exception is not handled. </quote> It's easy to reproduce: 1. Add a Timer (System.Windows.Forms.Timer) to a new WindowsApplication. 2. Set the timer's Enabled property = True. 3. In the timer's tick event, write: Throw New Exception 4.

    - Closing an application before it's opened. I've written a C# Windows Forms application. Now I've decided that it needs to check that the user is a member of certain groups as it's opening and close if they're not. A bit of research suggests that I won't be able to close the application before it's finished loading. this.Close() doesn't work in these situations. What's the recognized way of achieving this? I like to do things properly. If I was starting from scratch, would I create the project as a Console Project and use something like: Form1 form1 = new Form1(); form1.ShowDialog(); to display the form? (And find some way to hide the Console window.) Or do I create it as a Windows Application and find run the group membership checks as part of the first (somehow hidden) window and then call the main window with code similar to that above?

    - Mapping from DataGridView to the actual DataRow Hi, I have a DataGridRow which i fill with data from a DataAdapter. Now when the user selects a row in the grid, how do I find out which row datarow in the dataset is "selected"? I got this to work in asp.net 1.1 fairly easy, but how do i do it in winforms 2.0? I know I can just use SelectedRows[0].Cells[0].Value to get the value of the first cell in the selected row, but this is not what I want. What I basically want, is to be able to know which DataRow each DataGridViewRow represents. -- Thomas Due Posted with XanaNews version 1.17.5.9 "If you know the enemy and know yourself, you need not fear the result of a hundred battles.

Hi
It's a windows application and internet connection is not always available
for users.

The data is saved locally. I am thinking about using XML file because there
is not much data involved.

For report, we can use Crystal Report. For .net it should be 10.0 version
and above, right?

Other solution can be ActiveX report. The downside is it's not managed code.

I have thought of use XSLT and XML to create html file and load report in
browser. However I am not sure if there is any hidden problems for example,
the format of the report is not rendered exactly for each user because he may
set the font size differently. Is it a concern?

Has anybody worked with the 3rd solution?

Thanks
Frank
