    - app to use ftp to download a file I created a windows app written in vb.net that uses a shell command to use ftp to download a file. It works fine. I want to pipe the results of the ftp to a text file to analyze for errors. I can't get that part to work. If I do ftp by hand at a command prompt this works: ftp -i -s:ftpcommands.txt > ftpresults.txt This uses the commands in ftpcommands.txt to download a file and it pipes the results from the ftp to ftpresults.txt. When I try to do the same thing in vb.net code, it doesn't pipe the results to the file. I don't get any errors or anything. There's just no ftpresults.txt file there. I'm doing all this in the same directory that works using the command prompt directly. This is my code in vb.net: Shell("ftp -i -s:ftpcommands.txt > ftpresults.txt", AppWinStyle.MinimizedFocus, True) Any suggestions? Thanks. Tag: Problem Debugging Tag: 91259

    - user.config file In an ASP.NET web project, you can override web.config appSettings using a user.config file. Very handy with multiple developers working on the same project.. I tried doing a similar thing in a Windows form application but it didn't work. Here's what I tried: 1. Win Forms app.config file had this syntax: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings file="user.config"> <add key="input" value="From the app.config file."/> </appSettings> </configuration> 2. I added user.config to base diretory of project, and excluded it from the project. It's syntax is below: <appSettings> <add key="input" value="From the user.config file."/> </appSettings> Suggestions? http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/tdlg_ch4.asp implies that this is very possible.

    - MultiLine DataGridTextBox cell problem I have a standard Windows Forms DataGrid and wish to display 300 characters of text in a DataGridTextBox. I have made the data grid table style rows deep enough so that all the text has space to display. I have added the following code to the constructor for the form which contains the data grid:- ((DataGridTextBox)dgActPurpose.TextBox).WordWrap = true; ((DataGridTextBox)dgActPurpose.TextBox).Multiline = true; ((DataGridTextBox)dgActPurpose.TextBox).ScrollBars = ScrollBars.Vertical; but this only has an effect when the cell has focus. I would like to have all the text visible all of the time, not just when the cell has focus. The DataGrid is set with ReadOnly = true. Have I missed something, or what is the way to achieve this please? -- John Carrick Smith ============ -- John Carrick Smith ============ Tag: Problem Debugging Tag: 91251

    - Admin framework - advice needed I am looking to build (or utilize) an administration framework, We have many admin (back office) tasks that manipulate data that affects live web sites, Currently we have web forms, windows forms, scripts, etc. I would like to rationalize these into a single high level way of applying administration, My first idea was to use a "snap-in" type approach. For all admin tasks the following "concepts" need to be applied Authentication and Authorization (roles and groups) Auditing All admin forms should be easily accessible, different functions on each form may be restricted to certain users / roles / groups I have had a quick look at using MMC but I can't seem to find out what type of security model this offers. Any advice would be greatly appreciated Tag: Problem Debugging Tag: 91247

    - Need Help This is the description of my problems. I used three ways to develop irregular-shaped WinForms : 1. Firstly I set the form's FormBorderStyle property to None. I set the form's BackColor property to Color.Black and the Transparent key property to the same color, then I drew the form's background using Graphics.DrawImage Method. 2. Like Method 1, I first set the form's FormBorderStyle property to None, then I changed the form's Region property. I built the region by building a GraphicsPath Object from a background Bitmap I used in the application and stored it in my assembly to use it in the future. 3. I used a different way to draw the window. I drew the background image by using Win32 Function UpdateLayeredWindow and set the form's style to LayeredWindow. I got different results on them but none of them satisfied our requirements. a. By using the first method, I could draw the form fast but there was black margin around the shape and when I change the background Bitmap in runtime the screen would flicker even though I had used DoubleBuffer. b. For the second method, the flickering shrinks a lot, but the process of dragging the window cost a lot of system resources and there was still a black margin around the Bitmap object. c. The last method maybe the best of all, and the margin disappeared , the problem of resource consumption did not exist, the window didn't flicker any more. But there was a big problem on it : the controls on the form just "disappeared" but still could be used when I click the controls' region(or area), the system just ignored the images of the controls. The last solution seems fit us well and I want to know if there is some way to eliminate the problem of the last solution and make my controls visible. Or if can not, how can I do to improve the performance of solution 1 and 2? That's it. Great thanks. Tag: Problem Debugging Tag: 91239

    - TabControl and Form. Dispose() - Strange Behaviour Dear Group I wonder if you can help me with the following. I have a form (Form2) that contains a tabcontrol. If I click 'Tab2' Form3 should be displayed and 'Form2' closed. The instruction to close Form2 is in the Load event of Form3 but it actually doesn't matter where I put it. Every time I get this error: An unhandled exception of type 'System.ObjectDisposedException' occurred in system.windows.forms.dll Additional information: Cannot access a disposed object named "TabControl". Interestingly, If I have a button on Form3 to close the Form, Form2 closes just fine. However I want to close Form2 when Form3 has loaded. Also, if I place a button on Form to to open Form3 and don't use the SelectedIndexCHanged TabControlEvent, I also don't get this error. It's almost as it's looking for the TabControl when the error comes up. clsForms is just to keep track of my forms instances. Any ideas. Please let me know.

    - report solution suggestion 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 Tag: Problem Debugging Tag: 91234

    - 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: Problem Debugging Tag: 91231

    - 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: Problem Debugging 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: Problem Debugging 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: Problem Debugging Tag: 91197

Cheers, Dave Test #1 ====================== 1) Click on the row where ID = 1 2) Click "Add Row" button 3) Click on the cell ID = 2 Number = 4 4) Change the number from 4 to 5 5) Move off the row (i.e. hit the down arrow key) 6) Notice there are 2 rows with ID = 2 now 2, 5, 6 2, 4, 6 Test #2 ====================== 1) Click on the row where ID = 1 2) Click "Add Row" button 3) Click "Remove Binding" 4) Click "Add Binding" 5) Click on the cell ID = 2 Number = 4 6) Change the number from 4 to 5 7) Move off the row (i.e. hit the down arrow key) 8) Notice there are 2 rows with ID = 2 now 2, 5, 6 2, 4, 6 ========================== using System;

    - ColorDepth Would there be a problem if I set the ColorDepth of an image list to 24 or 32 bits? It seems to be working OK in my computer but I am wondering if other people will have a problem. I am going to assume that you would have to have a very old computer to not support these color depths, is my assumption correct? Thank you. Tag: Problem Debugging Tag: 91133

    - 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: Problem Debugging 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. Tag: Problem Debugging Tag: 91118

    - 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: Problem Debugging Tag: 91114

I have these lines in a button click

string string1 = textBox3.Text;
string string2 = textBox4.Text;
MessageBox.Show("here now");

at the first line I have set up a break point. When I run the application,
it does show the message box but it does not stop at the break point (set on
the first line).

I have no clue whats going on...

What is your build configuration? Make sure that you're set on "Debug".
