    - Multi-window application example Hi, I am porting an application from Windows Mobile to the desktop. This is my first .NET desktop forms application (my experience is in ASP.NET). I am looking for a sample application that employs a solid programming model for managing a multi-window application. This application has a lot of dynamiccally built forms and opens and closes forms as necessary and can have multiple forms open at once. Its very simple on Windows Mobile because all forms are always maximized and you can layer forms on top of each other with no problem. Thanks for any assistance. -Dave Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106910

    - Layered architecture Hi. It is often maintained, that a layered architecture is something one should consider in any nontrivial application (see e.g. Data Binding with Windows Forms by Brian Noyces). I have a VS2005 solution with 3 projects in it: 1. Adveita.UI - a WinForms executable for user interaction 2. Adveita.BLL - a library project for buisiness logic 3. Adveita.DAL - also a library project, for data access In order to achieve a full decoupling between the UI and DAL layers, I find myself writing wrapper classes in the BLL layer to present tables, columns etc. to the UI layer. Also, I am writing a lot of code to bind controls like text boxes to data and the like. I think, that the designer should be doing this for me in most cases and I that I am perhaps doing something basically wrong here. On the other hand, examples in books and downloadable samples are rather simplistic and hardly tackle questions like these. Can anyone comment on this, point out to me samples or articles addressing these questions. Regards, Gudni Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106908

    - Custom Form working at runtime but cannot be loaded in designer Hi, I have a custom form that works fine when I debug it or run it in release mode but cannot be loaded in the designer... Actually, it can be loaded in the designer when no control is on it, but the resizing tool (in the designer) is offset both horizontally and vertically and when I put a control on it, as soon as I save, the designer throws an exception (but cannot be reproduced everytime) and the form cannot be loaded anymore unless I remove all the controls from it... but the major problem is the offset of the designer... also, I'm unable to move the newly added controls on my form... I can resize them when I add them and after that cannot even select them... this behavior happens when I want to use the custom form (inherit forms of my projects from this form)... When I want to see the form in the designer (the CustomForm itself inherited from system.windows.forms.form) I receive and exception too (here it is) Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located. Hide at System.ComponentModel.Design.EventBindingService.EventPropertyDescriptor.SetValue(Object component, Object value) at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeAttachEventStatement(IDesignerSerializationManager manager, CodeAttachEventStatement statement) at System.ComponentModel.Design.Serialization.CodeDomSerializerBase.DeserializeStatement(IDesignerSerializationManager manager, CodeStatement statement) Events cannot be set on the object passed to the event binding service because a site associated with the object could not be located.

    - Exception handling, Retry, Resume Next There are situations where you want to retry/rerun the same code again (if user wants) for unlimited times for a particular exception thrown. For example in situations like there's no CD in the drive or some file is locked by another process you want to display message dialog to user with "Retry" and "Cancel" buttons (As Windows shows "Retry" option if no CD in drive) and if user clicks "Retry" you want to run the same code again that thrown the exception. How can I construct the same "Retry" exception handling behaviour in C#. Secondly, how can I construct VB6's "OnError ResumeNext" equivalent in C# for particular exception handling. "OnError ResumeNext" actually resumes with next instruction/code if a line/code produces an exception. For example in a loop if something raised exception I want loop to continue with next iteration. How can the VB6's "OnError ResumeNext" constructed in C#. regards, Adil Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106895

    - Control sizing bug for UserControl hosted in IE7 I have reported this bug on Microsoft Connect but have seen no activity so I thought I would post here and see if anyone else has been affected by this. I have written a UserControl and successfully hosted it in a web page. When this web page is displayed in IE7 the control gets shrunk to half size whenever you open additional tabs to display other pages. I think this happens because the pages are rendered at half size in the tabbed pages view. Has anyone else seen this? If so and you want some action, go vote on or validated my bug report on Microsoft Connect. http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=205530 Thanks, Peter Bromley Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106891

    - Automatically Wrap Text in Label I have the following scenario: I have a TableLayoutPanel in my form. In one of the cells I want to place a Label control to display some text. The label might have just a few words. It might have a paragraph. I would like the label text to automatically wrap inside the cell in the TableLayoutPanel. If the row in the TLP is not large enough, it should automatically grow so that it can display all of the text. 1) I have tried setting Dock:Fill and AutoSize:False on the label. This will cause the text in the label to wrap, but it will not grow past the size of the cell in the TLP. If I set the row in the TLP to be AutoSize, the whole row becomes hidden. 2) If I set it to Dock:Top, AutoSize:False, and set the TLP row to AutoSize, this works, as long as the height of the Label is set to a value sufficient enough to hold all of the text. But if the height is not big enough, the text gets cut off. In case 2 above, it seems like I am on the right track, and that it would work if I had some way of dynamically making the Label taller depending on whether it still needed to wrap the text. Any suggestions for me on how I can accomplish this? Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106890

    - Switching localizable forms language messes up design I have a C# windows forms project that was designed in Visual Studio 2003. It works great. I have recently decided to upgrade to VS 2005 and .Net 2.0. I opened the project in VS 2005 and it converted it fine. I fixed the odd obsolete line of code and it compiles and runs. The problem is that my previous design was done with the systems display set to Large Fonts. My new dev system is set to Samll Fonts because this is the default setting in windows. These means I have had to go into each form and modify it slightly but that is fine. Now, my program is setup to be localizable between english(default) and french. Whenever I need to make a change to a french version of a form I just change the language in the form properties to french and boom, there it is. Now this worked perfectly in VS 2003 but in VS 2005 when I try to change the language back to english(default) after making a mod to the french version, my whole form gets screwed up. The background colour of the form and almost all of the text box properties get reset to the windows default settings. The biggest problem about this is that it is a big form with over a hundred labels and text boxes so to have to change it back all of the time can be very time consuming. I have tried everything imaginable to get it to stop doing this. I even removed the french resx file, and switched my form to not localizable, then I switch it back and re-create the french resx file, and whenever I go back to english, it is all messed up. Does anyone have a clue as to what is wrong? Unfortunately I cannot post the code for the form as it is secret in nature.

    - Zorder and splash screen Hi, I have a form which is a splash screen. A static method is used by my main program startup to show the form, which creates the form on a seperate thread and shows it using Application.Run( splash ). The problem is when my main form shows and the splash hides, the main form ends up behind any other window display (such as my web browser or explorer windows). I've read this is because the first message pump that ends causes the application to deactivate, but I haven't been able to find a solution to this. I had replaced Application.Run with this loop: while ( !shouldClose ) { Application.DoEvents(); } Where should close is a boolean that indicates if the form should close or not. (Which is set by another static method called from the main thread). Any ideas? Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106874

    - Help with double-click and drag-drop Hi: I posted this 3 days ago in another V-Studio2005 group and got no replies. There seems to be better response to requests in this group. Hope nobody minds me trying for an answer here. I have windows forms .Net 2 app. in which I was using double click to activate a form. I also wanted to be able to drag items out of one form onto another. I got both working separately, but I can't seem to get them to work together. The mousedown event is trapped by my drag-drop routine. This prevents double-click. As soon as mousedown fires, the app thinks it is dragging out. The datagridview control will not accept to have both double-=click and drag-drop both as possible user-actions. Any help or ideas will be greatly appreciated. Thanks and have a great day!

    - cType error? I'm using several routines in my program that work on properties in a textbox. The KeyPress is one of them. They all work fine for all of the textboxes listed in the Handles ... part of the sub shown below. Except for one. I have one text box, txtAdd2, that ends up being passed to the subs as 'Nothing'. So when I try to reference the object in my subroutines I get the following error: "An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll Additional information: Object reference not set to an instance of an object." Here is the KeyPress event code. Stepping through the program the error triggers on the Me.SelectNextControl line because the sender is 'Nothing'. I get similar errors when sending a reference to txtAdd2 to other routines; Private Sub Enter_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtAdd1.KeyPress, txtAdd2.KeyPress, txtAdded.KeyPress, txtBDay.KeyPress, txtCity.KeyPress, txtEMail.KeyPress, txtFName.KeyPress, txtHPhone.KeyPress, txtJoined.KeyPress, txtLName.KeyPress, txtMPhone.KeyPress, txtState.KeyPress, txtStatus.KeyPress, txtWeb.KeyPress, txtWPhone.KeyPress, txtZip.KeyPress If e.KeyChar = Microsoft.VisualBasic.ChrW(13) Then Me.SelectNextControl(cType(sender, TextBox), True, True, False, True) End If End Sub Any help would be appreciated.

    - filtering DataGridViewComboBoxColumn contents 2 seperate but related questions 1) I have a DataGridView filled with an employee schedule, the employee is selected from a ComboBox column. Everything works fine so far. Over time, employees may be deactivated (but not deleted). The ComboBox dropdown is to list only active employees (i.e. filtered by an Active bit). This works too, but if an employee with existing lines in the schedule is deactivated, the name displayed in the ComboBox on the schedule DataGridView goes blank. It's just a display problem, the underlying data is OK and no exceptions are raised. In other words, I need the ComboBox to display ANY employee, but the dropdown to show only ACTIVE employees. What now? Custom control? --------- 2) Same project, different screen. The (nontechnical) customer decided to do some GUI designing on his own... yikes. He wants a DataGridView where the first column is ComboBoxes filled with inventroy item categories. Then the second column is to be a ComboBox of inventory items, and its dropdown should be filtered by the category selected in the first column. Usability-wise I think that makes good sense - but unfortunately I think it's not possible... is it? I suppose you could create a hidden column of BindingSources and set the filter when the first column validates, or something like that. Has anyone been through this? The inventory can contain thousands of items, even a sorted ComboBox column won't really get the job done. We almost need a "dropdown tree" column to drill down to the right item. Suggestions?

    - DataGridView always displaying a Vertical scrollbar I have managed to always display a vertical scrollbar in a DataGridView by subclassing the DataGridView and handling the VerticalScrollBar.VisibleChanged event. The problem is that the horizonal scrollbar appearance is based on the visible DataGridView view without the vertical scrollbar. So if the user does a resize, about half of the last column gets covered before the horizontal scrollbar appears. It seems that DisplayRectangle tracks the correct visible size but I can't find a way to change it that will effect the horizontal scrollbar. Overriding DisplayRectangle did not work. Thanks.

I am running windows XP home on two machines. I know, my friend who is running XP professional, at least on one machine is able to scan the other computer on the neck work with Norton antivirus. When I have tried it Northlands has found the drive but only scan seven files I am wondering if it is something to do with not running Windows XP professiona my friend gave me this command l\\<Computer Name>\C$ (we're computer name is the name of the drive) to test the network it could not find the path. Even though the path is correct I would appreciate any feedback on what I can try. And if that is something to do with Windows XP professional.

    - Opening a browser window from a Window Form Hi there, I'm trying to open a web page in a browser. I wanted to open the default browser on the computer, rather than limiting it to IE, so I did the following (web page has been changed to protect the innocent! ;oD) // botch - this gives an error if blocked by zonealarm or other firewall try { System.Diagnostics.Process.Start("http://www.google.com/"); } catch (Exception ex) { MessageBox.Show("Error while opening browser window. Check your firewall permissions.\nError returned was : " + ex.Message); } As the comment shows, if the .NET application's access to the internet is blocked by ZoneAlarm (or a similar 'outward bound blocking' firewall) then the Start() fails - but it does not return an error or exception, or indeed return at all. Stepping through in the debugger shows that the Start() never returns and the next line is not executed. Strangely, the UI keeps working, kind of; if you then do the above a second time then it gives an exception of 'The system cannot find the file specified'. Of course it works fine if the firewall allows access, but that's not much comfort. Does anyone have a solution? Failing that, can someone suggest another way to open a web page in the default browser that does not have the above problem. Failing that, can someone suggest the best way to open a web page in IE without the above problem? Thanks tons - this one's driving me crazy...

    - Blocking Cookies Hi there, Does anyone know how I can add sites to IE's cookie blocking system? I'm pretty sure it's possible, I've seen a program do it (though not in .NET 2.0). Ideas anyone? Thanks in advance, James CC Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106781

    - Get access to cookies from windows forms Hi there, I need to access cookies stored on a client computer from a windows form (in C#, .NET 2.0). I know that I can find the Temporary Internet Files stored in the Local Settings using TempInternetDir = Environment.GetFolderPath(Environment.SpecialFolder.Cookies) + "\\"; and then use standard System.IO functions, eg string[] cookies = Directory.GetFiles(TempInternetDir); string contents = File.ReadAllText(TempInternetDir + cookieName); Unfortunately with that there are several problems, specifically (a) I can't read cookie specific details, such as expiry date, internet address, etc., and (b) the system is 'glitchy', for example deleting a file with File.Delete(TempInternetDir + cookieName) deletes the underlying text file but it's still listed in Temporary Internet Files. Can anyone suggest a way to access 'Temporary Internet Files', and cookies contained within it, legitimately, and so read the details, edit files, delete files, etc. Thanks for your help in advance. All the best, James C-C Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106780

    - Different Column Widths I am trying to do a 'simple' task in a DGV control. The problem is this. I have an unbound DGV with all 'AllowUser' options disabled. RowHeader.Visible=False ColumnHeader.Text is labelled as needed. For simplicity the DGV has 7 columns and 15 rows. The 15 rows are populated and the DGV is made visible. Everything is just fine. But now I want rows 6,7 and 11,12 to have different column spacing to the other rows. I have not been able to find a way. I tried hanlding the DGV.CellFormatting Event but cant get the desired results. In other words I want one DGV control to have different column widths depending on row number? Can anyone out there help? Thanks -- Roger -- Roger Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106778

    - Unexpected events being raised when button is disabled I have 4 buttons ( 3 in one tab page 1 in another tab page) of a windows form. There is also a group of radio buttons. The single button on the second tab page is called Run. When RUN button is clicked, there is code to disable all the 4 buttons including the run button. However, the moment the line of code, run.enabled= false is reached the radio button clicked event gets fired. In the event handler of a button click when we try to disable the same button why does it raise a radio button checked event?? How do I avoid this Tag: Method Conversion from VB6 to VB.Net 2005 Tag: 106777

In vb6, I had a program that had the following code:
StrPtr
LenB
Picture1.Print
Picture1.CurrentX (& Y)

They don't apparently transfer over in vb.net 2005 - - -

I hate to admit it, but I found this code somewhere on line and I have never
used these properties/methods again for anything else and don't know what to
look for in place of them...

Can someone help me find the answers please?

Both are not required any more. For which purpose did you use the method?

> Picture1.Print
> Picture1.CurrentX (& Y)

Handle the picturebox' 'Paint' event and use 'e.Graphics.DrawString'
instead.

Yes.

I had stuff like that.

Embarrassing to ask, isn't it.

Do yourself a favor - re-write the app using updated principles.

Yes - look at the upgraded code to give yourself an idea in certain cases
BUT don't re-use the upgraded code ad hoc.
