    - Launching IE, with encrypted parameters, to an SSL website I have a Windows Forms application where I request a username/password from the user. When the user clicks a button, I would like to launch IE to a given page on my SSL webserver and send along the username/password pair that was provided by the user. I understand how to open IE to a specific website from a Windows Forms application using the System.Diagnostics.Process.Start method, but I don't know how to include the username and password as form fields in that request (so they'll be encrypted during transmission). Obviously I don't want to include that data as part of the QueryString ... My only thought is that I can create a temporary HTML on the client side which contains the username/password in hidden form fields and does something like onLoad="form.submit();" But this solution seems messy... Any ideas? Thanks, Michael Carr Tag: debug user control Tag: 67550

I have a UserControl with a ListView docked to the left edge and a TextBox that makes up the rest. I am able to add items to the ListView when a new line is entered in the TextBox (these items are the line numbers). What I am not able to figure out is how to update the view of the ListView when the TextBox starts scrolling vertically. I would like the ListView to show those line numbers only that the TextBox is currently displaying. It would be great if someone could help me out, Navin Tag: debug user control Tag: 67547

    - Orphaned ControlBox in MDI child So, I have this MDI application. Occasionally, if I have a few MDI children open, and then close one of them, the ControlBox for the MDI children becomes duplicated, right next to one another in the far upper right hand corner, below the ControlBox for the MDI parent. It has the appearrance of Minimize, Maximize, Close, Minimize, Maximize, Close(except it looks like the Underscore, Line at top of box, Capital X duplicated). Both of the ControlBoxes seem to work. However, if I close all of the MDI children, after the last one is closed, there is still a ControlBox remaining, orphaned, below the ControlBox for the MDI parent? Odd huh Michael Tag: debug user control Tag: 67544

    - Is there really no way to hide a TabPage? Hide and Visible have no effect. this.tabControl1.TabPages[iField].Visible = false; this.tabControl1.TabPages[iField].Hide(); I hear that the TabControl in the .NET framework is a wrapper of the Tab control in the Common Control Library.

    - ADSI with NT 40 I created a windows form in Csharp. I successfully installed the application on the target computer. The OS is NT40 with the latest service pack on it and .Net Framework 1.1. I also went to Microsoft website and download the ADSI for NT 40 and installed it on the target computer. The application (using ADSI) is looking at the NT group of the user that is currently logged in. When I launched the application, ther error came up and displayed a message saying: Can not find RADMIN32.DLL in the system32 directory. The machine where I developed it has Windows 2000. I guess Windows 2K has a DLL that NT does not. I tried to search on Google for RADMIN32.dll but no results came up. Can you help? Tag: debug user control Tag: 67539

    - Guidance needed with Drag and Drop style calander Hi, I'm currently pondering how to write a simple scheduling app in VB.Net that displays a horizontal monthly timeline of days, from left to write, and then colour coded bookings for each of the resource in a grid format underneath. When creating bookings I would like to be able to highlight the days that the booking spans for a resource, just like in Outlook Calendar where you can create an appointment by highlighting the number of half-hours it spans. Subsequently I would like to be able to resize the appointment, and drag and drop it either elsewhere in the persons timeline, or across to another persons timeline. It goes without saying that I would need to keep track of the booking movements before they are saved to the database. I have searched high and low for example code that would allow me to perform such functioality, but to no avail. Has anyone had any experience of this type of coding before who could point me in the right direction? Any help would be gratefully received. Thanks. Paul Tag: debug user control Tag: 67536

    - problem with axwebbrowser on tabcontrol in usercontrol Hoping someone can help me here..... I have seen numerous references from other people with a similar problem..... I have a Windows Forms usercontrol which contains a tab control with two tab pages, each of which contains an axWebBrowser control. I am navigating each axWebBrowser to a different word document, but, when I click on the second tab page, the second web browser does not appear. If I place the tab control straight onto a windows form then it works fine. Can anyone offer a workaround? Tag: debug user control Tag: 67535

    - Drag and Drop of Class Instance I've been experimenting with drag and drop. I have a program which displays a DataSet in a DataGrid. I have sucessfully used the MouseDown event to locate the appropriate DataRow and to pass it to DoDragDrop. When I drop it, I see an item of type DataFormats.Serializable. But what do I do with the data that comes back when you use e.Data.GetData? It's a System.__ComObject, and I don't know what to do with it. Can anyone point me to an exanple or article on doing this?

    - How to bind Data Grid to non-DataTable type, but still get auto columns (sorry about the earlier version of this, I pressed enter, and it sent it without getting a chance to write subject I've recently got involved in a project that requires me to use some other type of input that a DataTable as my input, such as an array list. What I'm tring to find out, is how can I use an arraylist (or maybe some better control) to populate a DataGrid so that the 'columns/fields' show up automatically. This would be very helpful in situations in which I would like to use the wizard like features of the datagrid such as the property builder Any help would be appreciated. Thanks in advance!!!!!!!!

    - Painting over an ActiveX-Control Hello, I am working on an enhanced HTML-Editor based on DHTMLEdit. So I created a subclass like that: public class HTMLEditor : AxDHTMLEDLib.AxDHTMLEdit I have created a lot of functions to insert Tables, Images, etc. Edit them, drag Table cells, etc... What I now basically want is to draw my own stuff in the editing window on top of that which is drawn anyway by DHTMLEdit. For example a grid like Visual Studio .NET does in HTML-View. Or drawing boxes over tables which the mouse is hovering like Frontpage 2003 does... I thought I simple override WndProc, catch WM_PAINT, let the base class do that drawing stuff and then I just paint my stuff over it, like that: protected override void WndProc(ref System.Windows.Forms.Message m) { base.WndProc(ref m); if (m.Msg == WM_PAINT) { IntPtr hDC = IntPtr.Zero; hDC = GetDC(this.Handle); Graphics g = Graphics.FromHdc(hDC); g.FillRectangle(new SolidBrush(Color.Red),0,0,100,100); g.Dispose(); ReleaseDC(this.Handle, hDC); } } I tried other things to get an instance of Graphics, like CreateGraphics-Member of Control, etc. When starting the app, I see that red rectangle, but a second later it's "hidden" by the HTMLEditor, and its never visible again. I also played around with the ControlStyles, but did not find anything that worked... Anyone has an idea? Thanks in advance, Phillip Schuster Tag: debug user control Tag: 67522

    - How to get instance of control by name Hi, imagine having an INI-file with entries like: # key=Control / value=Text property of control controlA=bla bla bla controlB=bla bla bla controlA and controlB are different controls of types like TextBox, etc. Closing form will write INI-file, storing control names and text property of these Loading form will read INI-file and set text value of corresponding control quite a simple task, if you'll do it as follows: .... switch (iniControl) { case "controlA" : controlA.Text = iniValue; break; ... } ... But what about a more generic solution? Assuming that the key-value of INI-file is a known control, an instance within the form, what about a solution like: - get instance of the control by its name - set value from INI-file to Text-property Tried to solve this by using reflection - something like GetType(iniControl), but never suceeded. What do you think how this could be solved? Thanks and regards - Jari Tag: debug user control Tag: 67480

I use the System.IO.DirectoryInfo to open information about the specific directory. I am then trying to query all of the images in that folder whether the extension be .jpg, gif, or bmp. So far I have not had any luck passing more than one extension to 'GetFiles(String searchPattern). Is there a way to pass more than one extension to this method? Also is there a better way to search for files? Something more along the lines of FindFirstFile from the Win32 API? Thanks for the help Brian Tag: debug user control Tag: 67472

    - Dll Import problem ** I forgot to ask one more thing, Just see the last few lines. I have a Dll written in C. And I want to Import that Dll into my C# program and use a function in the Dll. In a previous newsgroup article I saw that I may need to wrap the Dll in a C++ .NET class and then use that in my C# application. But when I run my program I get an error saying System.IO.FileNotFoundException: File or assembly name "abc", or one of its dependencies, was not found. File name: "abc" abc is my wrapper project class library. here is my wrapper class is given below. The lib name is wdll.lib and the header is dll.h. #include "dll.h" #pragma comment(lib, "wdll.lib") namespace MyWrapper { public __gc class Class1 { public: static void myfunc1(long JobNo) { _libmain(JobNo); } static char * myfunc2(void *vJobRec, short field, short subfield) { return (GETJF_NAME( vJobRec )); } }; } Here is the actual dll header file. extern "C" { void WINAPI _libmain ( long JobNo ); void * WINAPI _getjobfield ( void *vJobRec, short field, short subfield ); }; ..... and here is where I am calling it. using MyWrapper; unsafe { Class1.myfunc2(null,0,0); } It throws the exception here, System.IO.FileNotFoundException: File or assembly name "abc", or one of its dependencies, was not found. File name: "abc" ________________________________________________ So then I tried to acces the Dll in a more traditional way , but would result in the same error. Here is just a simple console application that I did, using System; using System.Runtime.InteropServices; using System.IO; using System.Reflection; using MyWrapper; namespace test { class Class1 { [DllImport("kernel32.dll", CharSet=CharSet.Auto)] static extern IntPtr LoadLibrary(string lpFileName); [DllImport("wdll.dll")] public static extern IntPtr _getjobfield([MarshalAs(UnmanagedType.LPStr)] string s, short i1, short i2); [STAThread] static void Main(string[] args) { // Esure current directory is exe directory Environment.CurrentDirectory = Path.GetDirectoryName( Assembly.GetExecutingAssembly().Location ); string dllPath = Path.GetFullPath( @"C:\SoftwareDevelopment\testing\testing\test\test" ); LoadLibrary( dllPath ); Console.WriteLine( _getjobfield(null,0,0) ); } } } ******* ****************************************************************************** And in the previous mail I for got ask one more thing since _getjobfield returns a char pointer how can I read that value. currently what I am trying to do is unsafe { Class1.myfunc2(null,0,0); } but when i DO THIS unsafe { char * p = Class1.myfunc2(null,0,0); } It say's can not convert sbyte* to char*. The thing is that I am sending char* so I do not know where sbyte comes from But it throws the exception, Can any one help. Thanks Tag: debug user control Tag: 67470

    - Font Class - a big performance eater? I was curious if anybody else noticed this fact. Everytime you use the font class, especially creating multiple instances of the Font class in an iteration, there is a significant performance hit. The way I noticed was due to a bug in my code. I have a list class where each item is a separate object with various properties, among which a Font. At some point I wanted to test my list with a lot of items so I made a loop that was creating like 10000 items, but I used a constructor that passes a font too and I used new Font(...). To my surprize and astonishement, it took an average of 7 milliisecond for the framework to create each item. I got into a sort of panic, as I thought that my event model was too extensive or I forget to dispose some objects. It turned up that when I removed the Font object from the costructor with a null, the average time went from 7 milliseconds to 0.02 miliseconds!! That is like 350 times faster... Now I am even worried about any place that I might use the font constructor. Did anybody noticed this behavior in other instances? Does anyone know an optimized way of using fonts thank you Iulian Tag: debug user control Tag: 67459

    - No-Touch Deployment app.config problem I'm having a very frustrating problem with a no-touch-deployed application and its app.config file. When it loads from a remote server, it cannot get any settings from the app.config file. In trying to locate the problem, I have tested the following things: 1. The application works flawlessly when deployed via XCopy. 2. The application works flawlessly when accessed on my own machine via http://localhost. 3. The app.config file is accessible. I can browse to it manually and download it. 4. The app.config file is being downloaded by the application and stored in the IE browser cache, but is still not accessible to the application. 5. Another application - a simple one for testing this situation - exhibits exactly the same behaviour. I have already removed the *.config mapping from IIS for the relevant directory, and, just like before, the app.config is still accessible. I have enabled anonymous access. Just like before, the app.config is still accessible. I have thus concluded that the problem is not with my server configuration. Is anyone able to offer any insight into the situation? Anyone else encountered this problem? John N Tag: debug user control Tag: 67451

The first form then needs to do something based on how the form was closed. how the code looks Dim tf As New frmNewLeague tf.ShowDialog() If < tf closed using save button > Then do stuff else do other stuff End If Is using a global variable the best way, or can you cature how a form is closed?

    - Radiobutton databinding: Hi, I have a radio button group which I want to bind to a table column whose value is a string. Based on the string value, I want to checkmark one of the radio buttons. Here is my code in an attempt to do this. But it fails. The events don't even fire. I don't know what I am missing. All other databindings (to text boxes and combo boxes even check boxes) seem to work fine. But then, those controls don't need datatype conversion either. Can somebody please help? CatalogsDV is a Dataview of my datasource. And I have a currencyManager that positions the data. I have no problems there since other controls seem to work. Binding b2b = new Binding("Checked", catalogsDV, Const.CATALOGTYPECOLUMN); b2b.Format += new ConvertEventHandler(FormatCatalogType); b2b.Parse += new ConvertEventHandler(ParseCatalogType); this.rdbtnB2B.DataBindings.Add(b2b); // // // // private void FormatCatalogType(object sender, ConvertEventArgs e) { if (e.DesiredType != typeof(string)) return; string ctype = (string)e.Value; if (ctype == "B2B") this.rdbtnB2B.Checked = true; else if (ctype == "B2C") this.rdbtnB2C.Checked = true; } private void ParseCatalogType(object sender, ConvertEventArgs e) { if (e.DesiredType != typeof(bool)) return; bool ctype = (bool)e.Value; if (ctype == true) e.Value = "B2B"; else if (ctype == false) e.Value = "B2C"; } I am confused with the complexity of Databinding. But trying to learn. I assume the above event methods are correct, at least logically. I have placed breakpoints inside both the above events. But they don't seem to fire at all. Can somebody please help? Babu. Tag: debug user control Tag: 67430

    - Tables don't show in drop down of tablestyle in property window of datagrid Ok I'm working on a custom IDE though it's using alot of the same technologies as the VS.Net IDE. I drag and drop the datagrid onto the form (root component) and there is a dataset with tables in the component tray. I then just set the datasource to the dataset and then the datamember to the table I desire. I then open the tablestyles and add a new one and hit the mappingname and hit the drop down and nothing shows up. What I need to find out is how the datagrid populates that list, something somewhere in my IDE isn't allowing the datagrid to populate the dropdown list with the tables in the dataset. So does anyone have any idea how that list gets populated Joe Tag: debug user control Tag: 67427

    - queueing messages Hi, Ok, since I began writing this post, I have figured out the majority of my problem. I started out without a clue about how to use messages in my application (not referring to System.Messaging, but to good old windows messages). I want a Win32 application that runs without a window. I figured out how to add a message filter to the application before calling Application.Run(). That solves the problem of catching the message. Now I cannot, for the life of me, find any references to how to put a message on the application queue. Any help would be greatly appreciated.

Start another instance of Visual Studio and attach it to the first one.
Use the first instance of VS to open your control in the designer.
Set your breakpoints in the second instance of VS.
