    - Howto: PassportIdentity class usage for MSN We want to support synchronizing some files with the users private documents share at "http://www.msnusers.com/My%20Web%20Documents/", so he is able to use e.g. it's documents from multiple client machines. The user provides and we store the needed credential infos (user/mail address and password) for the passport challenge/responses. Now my question: is there a way (like in MS Messenger) to provide these credentials in a https://... url as query params? Or: how we solve the login process via passport to access the WebDAV user folder at msn? We want to have a behavior similar to that of the windows system file explorer, if you open the colorfull butterfly icon folder in "My Network places": Open a credentials dialog (if we did not have them all) and then strait forward accessing the folder/file we need there. Related issue: It is currently a hassle or even not possible to get the .NET build in PassportIdenty work with a non-ASP.NET application. Is it possible without install/dealing the Passport SDK? All passport infos on the Internet we found are related to ASP.NET applications, but we need it in a Windows Forms App... Any help would be likly to have, we did not know who ever can help here... -- Thanks i.A. Torsten Rendelmann http://www.rendelmann.info/blog/ PS: Answer/Reply always to the group!

    - timer tick in form is re-entrant ?? Hi Anyone else encountered this problem? In a VB or C# project I have 2 forms. Both have a forms timer. The timer in the one of the forms is running at 55ms and raises an event which is handled by the first form. The handler disables, sets the interval, then re-enables the timer on its form. It also sleeps for 60 ms. The problem I've found occurs when the 55ms time overruns (say when the computer is doing something else ). After the timer has been re-enabled the first timer tick ( the one raising the event ) is called again even though the first instance is still running. Hence the call stack looks like this Tick1() RaiseEvent ... Re-enable timer Tick() The key here is the re-enabling of the first timer. If that is not done then the problem does not occur. Anyone else encountered this? It can't be considered normal behaviour for the timer tick can it? thanks for any input Liam More detailed code follows Public Class DialogForm Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " Event DialogEvent() Private Sub DialogForm_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing Timer1.Enabled = False End Sub Dim b As Boolean = False Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick If b = True Then ErrorLabel.Text = Str(Val(ErrorLabel.Text) + 1) End If b = True RaiseEvent DialogEvent() b = False End Sub End Class Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " Private Sub DialogButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DialogButton.Click Dim f As New DialogForm AddHandler f.DialogEvent, AddressOf DialogEventHandler 'f.ShowDialog() f.Show() End Sub Sub DialogEventHandler() Sleep(50) Timer1.Enabled = False Timer1.Interval = 1000 Timer1.Enabled = True End Sub End Class Tag: datagrid issue Tag: 73355

    - Returned values from web service is wrong Hey Im calling a webservice wich is returning a DataSet. In the DataSet, wich is generated from a SQL query, there is a date field. This datefield (datetime) has the value '12-04-2004' (Danish date format, or actually i think it stores it as italian in the database. Corresponds to DD-MM-YYYY). If i try to write the returned DataSets values out, in my program from the returned DataSet it keeps writing '11-04-2004 15:00:00'. What is that? Anyone who can explain to me what happens? Ive tried to see wether the value that is written is right, in the xml document that returns from the web service. The value looks like this: <dato>2004-04-18T00:00:00.0000000+02:00</dato> So i presume that the returned value is correct, but it is apparently wrong in the dataset on the client side, or it is converted to the day before during writing out the value. label1.Text = DataSet.Tables[0].Rows[0]["dato"].toString(); label1.Text is now '11-04-2004 15:00:00' even though the value in the returning xml document says the 12. April 2004 It happens with all of my dates. They are all set to the previous day at 1500 hours How can i solve my problem? Anyone knows anything about this? Please help.... -- Cheers Jimmy Tag: datagrid issue Tag: 73352

    - Crystal Report - Server Application Unavailable I have a Crystal report that I'm calling from a website - the report executes and then exports to a PDF, and then the PDF is then shown in a new browser window. It runs fine the first time, but any subsequent attempt fails at the point of exporting to PDF and the server eventually times out with a "Server Application Unavailable" message. The event log has a "aspnet_wp.exe (PID: 1764) stopped unexpectedly. " message logged. The only way I can do anythign further is to restart IIS or restart the aspnet_wp process. It tuns fine every time on the development machine, but on the Test & Production servers the problem occurs. Both Test & Production have had the IIS Lockdown run against them. Any ideas ? Thanks in advance for your help. Cheers, Cameron Tag: datagrid issue Tag: 73351

    - Running a VB.Net application in a language different than the Net FrameWork I have developped and tested a multilingual application which is running fine. When testing from inside .NET I created a drop down menu where I can choose the language allowing changing the language of the User Interface. I am storing this data in the registry so when I launch my application it is being loaded with that settings. This is working fine when working from inside VB.Net. Running the actual Exe it seems that my language settings are overwritten by the language of the Net Framework. Could it be true ? If it is true is there a way to overwrite this ?

    - via NUnit: Trace.Listeners.Add failure In my c# app I create a TextWriterTraceListener object and add it to the Listeners collection via a call to Trace.Listeners.Add(...). This works fine in my application; however it causes the unit tests to fail when the code gets run via NUnit tests. This appears to be some kind of permissions problem, probably related to the fact that NUnit is running my tests through reflection, but I don't have a clue how to proceed. Any suggestions or pointers would be appreciated...

    - Socket class and thread safety The Socket class is said not to be thread safe in the documentation. Logicaly, that would mean that thread safety measures are required when dealing with asyncronous socket operations. However, I have never seen any exemple deal with locking the socket reference in asyncronous context. What is the correct thing to do? Also, is there really any advantages to using sockets through a NetworkStream? Is there a prefered model when dealing with a binary protocol? Thank you very much, Etienne Boucher Tag: datagrid issue Tag: 73334

    - FileSystem Bug ? I have found a strange behavior I use FileInfo class to retreive LastWriteTime property of some file The file is just a JPEG image. When the image is editted by photosho (actually the image is rotated), the LastWriteTime property shows correct modification date. However, when I rotate the image with the built-in WinXP Image Viever, the property does not reflec the recent image change: it shows previous {image changing date} I checked Image properties using windows explorer, and it show exactly the same what FileInfo class does. If image is modified (rotated by winXP built-In Image Viewer, the "Modified" property does not reflect the recent image change. The only thing I noticed that changes are file attributes After rotation with WinXP Image Viewer, the "archive" attribute is removed So, is it a bug or XP Image viewer modifies files in a way that bypasses FileSystem .. or what ?? The most important thing I would like to know is actual file modification date (date of last modification), regardless of what program had been used to modify the file. Is it somehow possible Thanks In Advanc MichaÅ? Januszczy Tag: datagrid issue Tag: 73332

    - Help 3DES File Encrypt in VB6 to 3DES File Decrypt In VB.NET Hello, My problem is two fold. 1) I must support a deployed legacy application written in VB6 SP5. I need to export data from a database, compress it and the encrypt the data using 3DES (to prevent tampering) data gets transmitted at night to the home office of my company. Rewriting this application in .NET is not an option as the application was 5 years in development. 2) After I receive the data from the outlying offices, I need to Decrypt the data using VB.NET 2003 and the Cryptography namespace prior to transforming the data into an AS/400. I have successfully written VB6 code which encrypts and decryptes the data through calls to advapi32.dll. Unfortunately, any attempts to decrypt these files using VB.NET's Cryptography namespace results in a error and the attempt always fails. Can someone give me some examples or guidance in VB6 to VB.NET data 3DES encryption/decryption??? I am really stumped on this topic. Sample code would be nice!!! Remember the conditions - Encypt Under VB6 / Decrypt Under VB.NET 2003. Thanks underwmd Tag: datagrid issue Tag: 73300

    - adding grid to working currency manager disables addnew I created a group of 12 pretty typical databound forms around a currency manager. They all worked perfectly, patterned after chapter 13 of ADO.NET, Core Reference, published by Microsoft Press. In one case, the DataAdapter daDT filled the dataset instance dsDT1 with one table, DateType. The table had three columns: ID(autoincrement), DateType(string), and Active(boolean - default true). Two textboxes and a checkbox. The user could view the rows one by one with the usual <<<>>>, and edit, add, delete, update(the dataset, which was merely ending the edit), and updating the ms access database(submitChanges button). Also a cancel button. Pretty run of the mill Nevertheless, it acted quirky from time to time. One MVP took it upon himself to help me. It befuddled him as well. Finally he asked me to email the solution to time. After several days debugging, he found the problem. daDT.fill(dsDT1.DateType) caused the quirks. Instead I should use daDT.Fill(dsDT1, "DateType"). That solved the quirks Then I decided to make the form more visually appealing. I added a datagrid called dgrd whose datasource in the property box was dsdt1.datetype. I used the mousedown event and the hittest method to synchronize changes in the grid to the currency manager , and the handler for cm.positionchanged to synchronize the grid with changes in the position in the currency manager. Not hard, just adapted from the April 2004 msdn dvd Everything worked but the Add button. If I clicked Add, the textbox for DateType wouldn't clear. A row would be added to the grid with <null> in the DateType column, and various exceptions would follow depending on the button I clicked next I submitted a question more than a week ago and Cor Ligthert endeavored to help me. I thank him for that. We tried dataviews three different ways. In the form_load event I set the dgrd.DataSource = (DsDT1("DateType")), but the IDE wouldn't accept it. Cor suggested dgrd.DataSource = DsDT1.Tables("DataType"). It didn't help The problem has to be a defect in ADO.NET similar to the previous one. Rather than eliminate the grid, which adds delightful visual cues to the user, can somebody figure out a workaround Code follows.

    - Saving my Solution File How do I automatically save my project Solution upon exiting Microsoft Development Environment. Under the <Tools> <Options> <Environment> <Projects and Solution> <Build and Run Options> I have selected "Save all changes" but this does not save my solution file, consequently it does not update the "date modified" file attribute in order to display the proper date on the MDE Start Page. Should I be using another option if so which one? Tom Tag: datagrid issue Tag: 73291

    - Compact framework throwing formatException but 'normal' framework doesn't I'm trying to write a web services client using VB.NET (VS 2003) for a PocketPC (using .Net Compact Framework 1.0 SP2) either on the emulator or my device. Other services are working fine however when I try to call a service that returns a complex object I get a "formatException". The exact same code works perfectly using .NET Framework 1.0 on my PC. (Aren't the .Net Framework and .NET Compact Framework the same?) Unfortunately I don't have access to the server code (written in Java) so I can't simplify the object to identify which part is causing the problem (see below for the response I get back from the server) Is there any way to debug the code that is processing the response? I found some autogenerated code in VS which invokes the web service but not the code that actually reads the service response. Does anybody have any ideas as to how I can get this to work using the .Net Compact Framework?

    - System.ComponentModel.Win32Exception: The operation completed successfully Hi, I wrote a form that and behaves a lot like the desktop alerts in Outlook 2003 (fades in and out unobtrusively), then filled it with current condition weather data (www.weathercorneralert.com). I'm having the oddest exception that I can't track down. The app refreshes current conditions hourly (with a System.Windows.Forms.Timer). If I put my computer in stand by or hibernate, then bring it back up, I often get the following exception (type, message and stack trace): System.ComponentModel.Win32Exception The operation completed successfully at System.Windows.Forms.Form.UpdateLayered() at System.Windows.Forms.Form.OnHandleCreated(EventArgs e) at System.Windows.Forms.Control.WmCreate(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmCreate(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) This is the _entire_ stack trace. Note the lack of any user code in the stack trace. Also note that this build is built in debug mode; I was hoping to get some line numbers. I get the same thing when I build in release mode. I'm clueless as to how to prevent this exception from being thrown. I'm almost at the point where I'll just catch a Win32Exception in my Application.ThreadException handler and swallow it. Can anyone offer any suggestions? Thanks a lot in advance, Travis Tag: datagrid issue Tag: 73276

    - PocketPC 2003 unable to get device ID using KernelIoControl Hi, I can not get the device ID of PocketPC 2003 devices. I have been using the code at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/retrievedeviceid.asp The KernelIoControl call always returns a status of ERROR_INSUFFICIENT_BUFFER. It tells me that the required buffer size is 36, but gives this error even when I set the buffer size to 36. I read in another post that it has something to do with PocketPC 2003 apps running in user mode only, which does not give me the permission to call KernelIoControl? If thats the case, is there any way in PocketPC 2003 to get a device ID? Any help would be greatly appreciated. Thanks, Tony Tag: datagrid issue Tag: 73263

    - A simple Text Template tool Hi, I was trying to use Galois.Net to specify code generators and I had to look for some text template tool to simplify the syntax. I was looking for something similar to the syntax of an Asp.Net page; for example, a template file could look like the following: <%@ Assembly Name="ReturnString.dll" %> <html> <title>Testing generator</title> <body> <p> Hello <%= ReturnString.Val() %> <p> </body> </html> and if the ReturnString.dll is compiled from the following code: public class ReturnString { public static string Val() { return "World"; } } we should expect the output to be: <html> <title>Testing generator</title> <body> <p> Hello World <p> </body> </html> I wrote such a tool and I decided to post here because it might save other people a few hours of works since it was not completely trivial. Galois.Net can be found at http://www.a2ii.com/galois/index.htm .And using it to specify code generators, I have the impression that "I'm going places". I haven't done much testing but it was sufficient for my need. To use it, you should compile the code below e.g. "csc TextTemplateTool.cs". And run it, with the command: "TextTemplateTool hello.txt" where you saved the template text above in a file named "hello.txt". (You should also have compiled the ReturnString.dll assembly i.e. csc /out:library ReturnString.cs). NOTE: the "code behind" facility expect the dll to be in the same directory as the application). I have tried to keep the code to a strict minimum. You shouldn't have problems extend it to suit your needs.

    - Problems running apps on Citrix for non-admins My managed WinForms application is running fine on Citrix when logged in as a local administrator. When running it as a normal user, it seemed not to even start. To diagnose the problem, I wrote a simple HelloWorld WinForms app that has the exact same behavior. To continue the investigation, I ran SysInternal's FileMon program which revealed that a drwatson.log and user.dmp file were being created. Apparently when an regular user runs a .NET app on our Citrix server, a stack overflow is occurring. Has anyone got any ideas. I'd be happy to forward anyone interested the drwatson log file.

    - RichTextBox flicker solved The RichTextBox control in .NET (1.1) seems to have a flicker problem. A search of google revealed a lot of advice to remove flicker when reformatting and coloring the text, but no one seems to know how to remove the flicker when you simply enter text and there's more than about a thousand characters. To see this problem, drag a rich text box onto a form. Make it around 600 by 600 pixels, and turn the font up to 12 pt. Run the program and enter four or five lines of text. You get a lot of flicker on any further edits, and the problem gets worse as the control gets bigger and the length of text gets higher. The answer seems to be to add this code to a subclass of RichTextBox, which throws away a particular event. I'm not sure how it works, and YMMV, but my homegrown MySQL based personal journal software is now much more pleasant to write in. class FlickerFreeRichTextBox : RichTextBox { protected override void WndProc(ref Message m) { if ((m.Msg != 0x2111) || ((((uint)m.WParam >> 16) & 0xFFFF) != 768)) base.WndProc(ref m); } } I'm only posting this because I had quite a time finding the answer, and I thought this would make it easier for future seekers. It's amazing a bug this big got into the framework. Well, appalling, at least. Chris Capel Tag: datagrid issue Tag: 73244

    - What does GC.GetTotalMemory really tell us? Jon Skeet posted some code in another thread using the GC.GetTotalMemory(true) method as a way to demonstrate the amount of memory being allocated for a certain data type. That method was new to me and I thought it looked like a great simple way to implement some general memory monitoring. So I put a timer on my Mdi parent form and had it display the results of that call every couple of seconds. When the results were pretty weird compared to what I expected, I wrote the following console app. I think I understand why the results do what they do except: - Why the big 11k jump when the hog is created? Is that mostly the MemoryHog class itself? - Why the jump and not drop when hog is set to null? Also, if I understand the documentation for passing true in the parameter, doing so doesn't necessarily guarantee collection of all generations, only whatever can be done in a preset amount of time. Not that it probably matters in my scenario, but just for my curiosity. -------------------- using System; using System.IO; namespace JunkConsoleApp { public class TestClass { public static void Main() { long howMuchBefore = 0L; long howMuchDuring = 0L; long howMuchAfter = 0L; long memorybeforeCall = 0L; long memoryAfterCall = 0L; howMuchBefore = GC.GetTotalMemory(true); Console.WriteLine("Memory Before:\t\t{0}", howMuchBefore); MemoryHog hog = new MemoryHog(); howMuchDuring = GC.GetTotalMemory(true); Console.WriteLine("Memory with hog:\t{0}", howMuchDuring); hog = null; GC.Collect(GC.MaxGeneration); // Just to be absolutely sure! GC.Collect(GC.MaxGeneration); howMuchAfter = GC.GetTotalMemory(true); Console.WriteLine("Memory After:\t\t{0}", howMuchAfter); Console.WriteLine(new string('-', 50)); memorybeforeCall = GC.GetTotalMemory(true); Console.WriteLine("TestMethod-Before call: \t{0}", memorybeforeCall); TestMethod(); memoryAfterCall = GC.GetTotalMemory(true); Console.WriteLine("TestMethod-After return:\t{0}", memoryAfterCall); Console.WriteLine(new string('-', 50)); memorybeforeCall = GC.GetTotalMemory(true); Console.WriteLine("TestMethod-Before call: \t{0}", memorybeforeCall); TestMethod(); memoryAfterCall = GC.GetTotalMemory(true); Console.WriteLine("TestMethod-After return:\t{0}", memoryAfterCall); Console.WriteLine(new string('-', 50)); Console.WriteLine("Press a key"); Console.Read(); } public static void TestMethod() { long memoryAtStart = 0L; long memoryWithHog = 0L; memoryAtStart = GC.GetTotalMemory(true); Console.WriteLine("TestMethod-Start:\t\t\t{0}", memoryAtStart); MemoryHog hog = new MemoryHog(); memoryWithHog = GC.GetTotalMemory(true); Console.WriteLine("TestMethod-With hog:\t\t\t{0}", memoryWithHog); } } class MemoryHog { private string s1 = "hello"; private string s2 = "hello"; private string s3 = "hello"; private string s4 = "hello"; private string s5 = "hello"; } } // namespace JunkConsoleApp Tag: datagrid issue Tag: 73219

    - How do I retrieve the Control Type Name? I am writing an application (in C++) to interrogate the controls on any currently running .NET application. Most of the information I need I can retrieve from the window and class information available through the HWNDs retrieved using the EnumChildWindows() API. My problem occurs with controls that have the class name like 'WindowsForms10.BUTTON.app3'. So far I have seen this class name used for button, checkbox, radio button and group box controls, and basically all the other windows' styles are the same for each control type. The only way to distinguish these controls is by the control type name, and as far as I can see this property cannot be accessed from an external process. However I have noticed that at runtime controls within a .NET application seem to have a property/variable called 'WM_GETCONTROLNAME' which appears to me to be a type of windows message. Sending this value as a windows message to a .NET control has no effect. Could someone please tell me if this WM_GETCONTROLNAME can provide me with the functionality I need or do I need to inject my own code into the running process in order to retrieve the information I need from the inside???
