    - Maintaining and Using App Login details Hi, I'm developing an Windows forms based app that will draw data from a SQL Server 2000 system, that is set to use SQL Authentication (i.e. connection string must pass uname:pword). Given that various forms will need to use a SQL connection to generate data for data grid's etc ... how can I pass this authentication information around the various forms? A solution is to start the application from a VB.NET class, that has a shared member with the connection string (set once the user completes the login) Or create a shared connection object? Should I create a new connection object for each form? I currently test whether the login credentials are correct by enclosing within a try..catch clause an attempt to open and close a connection, failure will indicate invalid details (or perhaps a dead SQL Server!) ... any improvements on this? I assume that when using the form designer in VS.NET that if I manually program the connection (i.e. outside the section of code written by VS.NET ) that I can point the adapters/datasets etc. to the required connection. There are a few questions here ... but I've not so far found any answers here, on Google or elsewhere :( ! Thanks in advance for help Tag: Shockwave Player in Windows Forms? Tag: 77795

    - KeyUp event routing issues in Windows Forms. I believe I have found a bug in how keyboard events are routed in Windows Forms. I am not sure if this is a bug or how to work around it. MessageBoxes (MessageBox.Show) that are opened over top of a form end up routing their KeyUp events to the active control beneath the messagebox. For example, if I have a TextBox control focused on a form, and I open a message box, pressing "enter" to close the message box causes the TextBox control to receive a KeyUp event for the enter that was pressed in the dialog! It's almost as though the message is getting routed to the incorrect location. To reproduce this problem, create a new Windows Application (C#) project in Visual Studio 2003 (.NET 1.1. The issue occurs in the service pack edition as well). Drop a TextBox control onto the form's canvas from the toolbox. The bug occurs in any control that can receive focus, but in this case I will use a TextBox. Add a MouseUp event handler to the textbox with the following code: private void textBox1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e) { MessageBox.Show("The textbox was clicked. Pressing 'enter' on this dialog will cause the keyboard event to be incorrectly routed to the text box."); } Then add a KeyUp event handler to the textbox with the following code: private void textBox1_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { MessageBox.Show("An Enter KeyUp event was received by the text box. If you pressed enter to close the dialog, this message was incorrectly received! Pressing enter again on this messagebox will cause an endless loop!"); } } Save the project and then run the application. Click on the textbox to cause the messagebox to appear, then press the enter key while the messagebox is focused. The KeyUp event was routed to the wrong location, possibly causing undesired behavior! I noticed this bug with we were writing "ESC" key handling code in our application to close documents. A messagebox would appear, and if the user pressed "ESC" to close the messagebox, the ESC key event would get routed to the document, which would cause it to close - definately not correct behavior! :( I don't have the KeyPreview property enabled on the form. Is there any work around for this? KeyPress and KeyDown don't get executed however. I suppose I could move the code into the KeyDown event. Tag: Shockwave Player in Windows Forms? Tag: 77785

    - SelectedIndexChanged event in comboA causes same event to fire in comboB I have a vb.net 1.1 winforms app and have several combo boxes on a form 2 combos have the same data and are populated from the same data table using the bind method. One is the ShipToAddress and the other is the BillToAddress. when the user selects an address in the shipto combo, after its SelectedIndexChanged event fires, the SelectedIndexChanged event fires in the BillTo combo which, of course, is causing big problems. Why is this? is it because they are bound to the same data table? Is it a bug in vs 1.1? Can anyone recommend a fix or work around for this? Thanks. -- moondaddy@nospam.com Tag: Shockwave Player in Windows Forms? Tag: 77784

    - Form with background transparency issues Recently I wanted to create a small little program that could sit= on the desktop and not block the desktop wallpaper=2E There are= two methods to accomplish that ( that I am aware of )=2E 1) create a bmp as a background image and set the transparency= key to match its color 2) specify the form's background color with a matching= transparency key Now my issues with both methods, but first it should be known= that I have set the forms to have no border or title bar and= have implemented code that allows me to click-and-hold anywhere= on the form and move it=2E The data actually displayed on the= form is just text and one rectangle, all drawn by me ( there are= no controls on the form itself )=2E 1) I have two issues with this method, although it is what I'm= prefering to use at the moment=2E The first seems to be the= discrepancy between how the program is handled when the= computer's Color Depth is 32bit or when it is less than 32bit (= 16bit )=2E When the color depth is 32bit then I am able to click= on the entire area the form inhabits ( even that which is= transparent ) and move it, but if the color depth is less than= 32bit ( 16bit ) then only the drawn text or rectangle outline (= since it has no fill ) can be clicked to drag the program= around=2E Clicking on the transparent areas just passes the click= through the form to whatever is below ( even when I know the= form has focus )=2E I'd like to be able, regardless of the= desktop's color depth, to click anywhere within the form area= and move the application=2E The second issue I have with this method occurs when I take my= executable and put it on another PC ( my PC is XP Pro, the other= PC is XP Home=2E=2E Both SP2 )=2E The problem is similar, but a= little different=2E When the 2nd PC's color depth is at 32bit,= the transparency does not work=2E The green/lime ( that's the= transparent color I'm using ) background shows=2E Needless to say= this is not acceptable=2E When I change the color depth to less= than 32bit ( 24bit this time ), the transparency actually works,= but I come across the same issue of clicks on the transparent= areas just passing through=2E 2) With this method I have not tried it on a 2nd PC yet ( I don't= have it available where I am atm )=2E Its basically the same= "issue" as mentioned above with color depth less than 32bit,= except it does it with a color depth of 32bit and 16bit=2E Clicks= on the transparent areas just pass right through=2E I'm tempted= to just go with this method and possibly make one area on the= form that is meant to be used to drag it around ( similar to the= idea of the box that appears to move tables in MS Word ), but= I'm hoping there's a solution I'm unaware of before I do that=2E Anyways, all of this brings up some interesting questions=2E -What does color depth have to do with transparency handling? -Does the version of XP ( Home or Pro ) handle transparency= differently? Probably some more questions also=2E Not sure if it matters, but I'm doing all of this in C#=2E Any help or suggestions offered will be greatly appreciated=2E -------------------------------- From: othell m=2E ----------------------- Posted by a user from =2ENET 247 (http://www=2Edotnet247=2Ecom/) <Id>n5f4+mRIPU647s2eV3QftA=3D=3D</Id> Tag: Shockwave Player in Windows Forms?

    - Source for multi-track editor? Hi, I need to build a testing scenario generator that will create binary messages for an application we have built. The UI would look like a movie editor in that it would have parallel timelines for the actions of several people and several machines. The user would be able to lay down action icons on the timelines to show what was going on at any given time and specify the some properties of the action. At some point the user could click <Make Scenario> and all the corresponding input for testing would be generated. What I'm wondering is anyone knows of some source code in C# for a similar kind of editor that might serve as a starting point. Even a custom timeline control that could be replicated would be a good help. Thanks! Tag: Shockwave Player in Windows Forms? Tag: 77766

    - Disable Task Manager I'm trying to figure out how to PROGRAMMATICALLY disable the Task Manager while logged in as a "non-administrator" user (only belongs to the "Users" group). I know I can programmatically disable the Task Manager by having my app write a 1 to the registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System. Unfortunatley this only works, though, if the user who is running the app is logged in as an Administrator. When I try to run the app as a just a regular "non-administrator" User I am not able to write to the registry! So... Is it possible to do this? If so how? Tag: Shockwave Player in Windows Forms?

    - Detecting idle time from a .Net application I'm having a lot of trouble finding a universal and stable solution to the problem of detecting a session's idle time. I have a .Net application that runs in the system tray, much like many of the messenger services out there. From what I've read in the newsgroups, there are several mechanisms that I can try, but the biggest problem is that I have to get it working on Win98, WinME, Win2K and WinXP. The options I've found are: 1) On a timer, use GetLastInputInfo to check the last input event No good. This requires Win2K and up - I need to run on 98 and ME 2) Add a low-level mouse and keyboard hook in my .Net application using SetWindowsHookEx specifying the hooks WH_MOUSE_LL and WH_KEYBOARD_LL Again, works great in XP, but WH_MOUSE_LL and WH_KEYBOARD_LL are incompatible with 98 andME 3) Add a global mouse and keyboard hook in an external DLL using SetWindowHookEx and WH_MOUSE and WH_KEYBOARD This work fine accross all platforms, but for some reason whenever the screensaver kicks in, my hook stops receiving events. So my question is, is there another solution I should try, or is there something I should be aware of that could get any of the above solutions to work? Tag: Shockwave Player in Windows Forms?

    - delete selected rows from a datagrid I have a datagrid whose datasource is a datatable. I want the user to select (multiple) rows in the datagrid, press a button and have the selected rows deleted. Iterating through the rows in the datagrid and testing to see if each is selected and then deleting the associated datarow from the datatable is probably inefficient but nevertheless doesn't work because the selected rows in the datagrid are reset as soon as the first record is deleted from the datatable. Is there an obviously correct method for doing this? Tag: Shockwave Player in Windows Forms? Tag: 77763

    - Newbie: Dataset - ComboBox synchronization Hello, I have two questions involving Datasets and populating ComboBoxes and other controls with them. 1) Two cmbboxes are populated by two different fields of the same table and, of course, synchronized. However the second field is not required in the DB and missing contents sometimes. Ex: Field1 Field2 john 1990 mary paul anna mario 1967 james .....,etc. So when the user scrols through cmbField1 there is no problem, however if you want to scroll through the year there are big gaps that you go through because there is no contents there. Is there a way to get around that and STILL keep the cmb Boxes synchronized? 2) Now, after having the above from the same table and trying to get *Related* info from another table in my DB (of course still synchronized with the other two controls) I added a second table to the dataset with the INNER JOIN info. I access the new field by : Table1.field3. But field3 belongs to Table2 !!! not Table1! Is this normal? People say it's not a good idea to add more than one table in the same dataset. If this is true how can I get Relational information that is still synchronized? (i.e. fields 1 and 2 from Table1 and field 3 from Table 2) The fact that I get what I want is not enough. I need to know if it's the right way for my case and if there is s better way. Any help/feedback would be Greately appreciated. _steve_ Tag: Shockwave Player in Windows Forms? Tag: 77762

    - Combo Box Display Member is reset Context: setting a collection of business objects as the DataSourceof a ComboBox. The collection itself extends CollectionBase, and has public properties exposing the desired display and value members. In this particular case, the display and value member is "Value". Prior to setting the combo box datasource, the display member and value member properties are set, then the datasource itself is set. So, before setting the DataSource, the DisplayMember = "Value", but after setting the DataSource, the DisplayMember reverts to "". To put a twist on the issue, the second time that the DataSource is set, everything works as it should... Thanks for any and all input. -- Sancerre Tag: Shockwave Player in Windows Forms? Tag: 77758

    - MSComm doesn't fire OnComm event in a User Control Iâ??m developing a user control (in C#) that encapsulates the MSComm control. MSComm control is available as a COM component. So, Visual Studio.Net automatically prepares an Interop wrapper for this component. I want to use my user control in a C# windows application. Iâ??m able to send the data through this user control. But the problem is that my user control doesnâ??t catch the OnComm event. Iâ??m sure that there is no problem with the settings of MSComm control. This is because when I put an MSComm control in a separate windows application and then tried to catch the OnComm event, it worked fine and I got all the data from the Input property within the event handler. To Summarize: MSComm control doesnâ??t fire OnComm event in a User Control application. MSComm control does fire OnComm event in a Windows application.

    - Problem with Creating User Profiles on Windows XP Hi all, Please ignore the other post.. The cat jumped on the machine and sent it before I could stop it!! Was wondering if anybody has expericence this problem.. I am writting an application in C# using windows forms, to create windows user profiles and then updating the registry information for the new profiles. I have managed to create the user successfully and thought that I was writting the registry information correctly. That was until I checked the 'C:\Documents and Settings' Directory, when I noticed that the new users directories did not reflect their names. But instead comprised of non printable characters!!! Here is the code sample in C# ////////////////////////////////////////// DirectoryEntry NewUser; DirectoryEntry AD = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer"); // delete user when existing try { // this throws when no such user NewUser = AD.Children.Find(strNodeName, "User"); MessageBox.Show("User already exists!!"); return; }// Catch not found exception catch(COMException cex) { Console.WriteLine(cex.Message); } // Add user using the user schema NewUser = AD.Children.Add(strNodeName, "user"); NewUser.Properties["description"].Add(this.txtFirstName.Text + " " + this.txtSurname.Text); // NewUser.Properties["PasswordExpired"].Add(1); // user must change password at next login // Set user flags sample here sets Account disabled, pwd can't change // this flag is different for LDAP accounts NewUser.Properties["userFlags"].Add( UF_NORMAL_ACCOUNT | UF_DONT_EXPIRE_PASSWD ); // invoke native method 'SetPassword' before commiting // for AD domain accounts this must be done after commiting NewUser.Invoke("SetPassword", new Object[] { this.txtPassword.Text }); NewUser.CommitChanges(); // Add user to guests alias DirectoryEntry grp = AD.Children.Find("Guests", "group"); if(grp.Name != null) { grp.Invoke("Add", new Object[] {NewUser.Path.ToString()}); } MessageBox.Show("Account Created Successfully"); AD.Close(); ////////////////////////////////////////// Then I proceed to update the users Registry information!! At this point their is no Directory for the user in "C:\Documents and Settings\" directory ////////////////////////////////////////////////// NativeMethods._PROFILEINFO profile; IntPtr hToken = IntPtr.Zero; hToken = NativeMethods.CreateLogonToken(UserAccount, UserDomain, UserPassword); if(hToken != IntPtr.Zero) { profile = new NativeMethods._PROFILEINFO(); profile.dwSize = Marshal.SizeOf(profile); profile.lpUserName = UserAccount; // Directory Still Not Created at this Point!! int ret = Win32.LoadUserProfile(hToken, ref profile); // This function Invokes if(ret != 0) { // Use WMI to get the SID of the user (this requires W2K3 or XP) using (ManagementObject account = new ManagementObject("Win32_UserAccount.Domain='" + UserDomain +"',Name='" + UserAccount + "'")) { account.Get(); // Get key wich is the root for the users hive loaded in HKU UserSID = account["SID"].ToString(); if(UserSID.Length != 0) { // Now update the registry information for this user!!

    - Stack Trace Fails To Report Line Of Exception? Greetings, I have been capturing and logging exceptions in an application I developed. I've noticed for some time now that certain exceptions track back to the Application.Run method and provide no other line number useful for identifying the actual line throwing the exception. For example: at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef hWnd, Int32 nCmdShow) at System.Windows.Forms.Control.SetVisibleCore(Boolean value) at System.Windows.Forms.Form.SetVisibleCore(Boolean value) at System.Windows.Forms.Form.ShowDialog(IWin32Window owner) at System.Windows.Forms.Form.ShowDialog() at System.Windows.Forms.ThreadContext.OnThreadException(Exception t) at System.Windows.Forms.Control.WndProcException(Exception e) at System.Windows.Forms.ControlNativeWindow.OnThreadException(Exception e) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageA(MSG& msg) at System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at Clarity.Cashflow.Interface.TransactionForm.Main(String[] args) in c:\documents and settings\mlanza\my documents\visual studio projects\clarity.cashflow.satellite\interface\transactionform.cs:line 369 Line 369 appears below: TransactionForm frm; try { frm = new TransactionForm(); Application.Run(frm); //line 369 } catch(System.Exception ex) { Core.ErrorLog.AddEntry(ex); } As you might guess, this is not very useful. Of course, I know the exception was thrown somewhere within the context of my whole application, just not the actual line number. Yes, there are a number of clues provided in the stack trace, but nothing half as useful as an actual line number. My guess is that for this to happen, the actual line number must not be wrapped in a try-catch block. Now, for the most part, I have try-catch blocks everywhere throughout my application. Upon recent review I discovered I was doing something unusual -- I have try-catch blocks wrapping calls to events that are handled in turn by the even subscriber. When I wrote this logic it was my understanding that such a try-catch block would still do the trick. For example: try { RequestInputEventArgs ri = this.OnRequestInput("Enter Transaction Remarks", prompt, cdt, false, String.Empty); } catch(System.Exception ex) { Core.ErrorLog.AddEntry(ex); } The subscriber method: private void TransactionManager_RequestInput(object sender, RequestInputEventArgs e) { InputBox input = new InputBox(e.Caption, e.Prompt, e.DefaultText, e.ValidDataType, e.AllowEmptyString); input.ShowDialog(this); e.Cancel = input.Cancel; if (!e.Cancel) e.InputText = input.InputText; } As you can see, there in no error handler in the subscriber. I am assuming the error handler in the class raising the event is still in effect for catching errors, even those thrown in the subscriber. Is this true? If so, does anyone have an other ideas why my stack traces aren't pinpointing the actual line numbers? Mario T.

    - Newbie: Aligning Labels and TextBoxes on form Hi, When I design forms, I frequently have a lower-right aligned Label to the left of a TextBox. For example, I might have a Label with the Text property set to "Name:" and a TextBox to the immediate right where the user types his name. It's very hard to get the bottom of the label to align with the bottom of the text box. I discovered that VS.NET will perform the alignment for me if I select both items and use Format | Align | Bottoms. When dealing with long forms containing dozens of Label-TextBox pairs, I run into problems when I try to select ALL of the controls and, for example, move them all down an inch or two. I might do this if I realize that I forgot to include a particular label-textBox pair at the top of the form. When I move everything down (or up), I lose my alignment. The Labels and TextBoxes no longer have aligned bottoms. They are close, but not a match. This means I have to re-select each of the pairs and align them one by one EACH and every time I decide to change the form in a way that moves these pairs around. This is getting frustration for me. Is this a bug? Is there a workaround? Thanks. Sal B. Witness Protection Program ID#19730127 Tag: Shockwave Player in Windows Forms? Tag: 77714

    - newbie question: how to set a launched process (by Process.Start methods) as Modal I am using C#.NET WinForm. The scenario I have is: a WinForm child form launches a process using Process.Start(app_name). Other than checking the HasExited property and waiting, is there a way to forced a launched process (a third party application) as Modal (i.e. user has to respond to that process before get back to the WinForm application)? Thanks in advance for the help. MichaelJ Tag: Shockwave Player in Windows Forms? Tag: 77711

    - Object's Form Text or Name? Hi All, I am trying to figure out how to get an object's Form Name or Text value. If I have a ListView object called LV1, I want it's Parent Name/Text. Using the Parent Object will not do because the ListView may be contained within other objects such as Panels, Groups, or Tab Objects. Any ideas would be appreciated, John.

    - MouseEnter MouseLeave BUG - form caching? Hi all, I have been told of a mouseEnter mouseLeave BUG, that I have experienced (wich I can't find in the KB). For a brief introduction I'll explain it: The first time you show a form, mouseEnter/mouseLeave events of child controls fire correctly. When you close the form and show it the next time, only the first mouseEnter event (for the controls that had previously fired it) works, then no more mouseEnter/mouseLeave events are fired, no matter if you close the form and show it again. I have experienced this the first time with a picturebox, but lookig for other ways to do what I wanted to, I notice that the problem is at least with labels, buttons and pictureboxes. So I guess it is a bug of the framework for windows forms. My question is... I want to cache objects that include forms. I don't want to instantiate them all the time... is there a way to "clear" event wiring/messages of the form (remember that the first time the form is showed everything works fine)? Also, will that be the same overhead of destroying/recreating the object? Any other ideas for form caching are welcome... TIA, Pucara. Tag: Shockwave Player in Windows Forms? Tag: 77693

    - Sorry if this is oin the wrong place I am not getting any feed back at all. Is this a really stupid question or is it just that knowone has an answer? Hi All, I not sure where to ask this question so I will start here. I have a piece of wireless hardware that streams music from my PC to my HiFi. Running on the PC is a windows service that the wirelss device talks to. I would like to find out how they communicate with one an other. When I select an album on the wireless device and press play it must send a message or raise an event which the aforementioned service traps or responds to by looking in its database and streaming my selection. I would like to knock up a little catch all app which I could use to try and track what was going on and any pointers would be much appreciated (VB6 or VB.NET). Sorry if this is vague but its way of my normal path. Thanks for any help. Geoff. Tag: Shockwave Player in Windows Forms? Tag: 77689

There are plenty of posts regarding using a Flash player in standalone
Windows Forms apps, but what about the Shockwave player? I don't know
much about the differences between Shockwave and Flash, but I've been
told that you can do far more with Shockwave.
