    - Managing two connected forms Hi all, in my application I need to show a form that contains text box where user can edit patterns. When text in the text box changes, second form displaying the list of items matching the current pattern is shown. The problem is that I would like the first form to hide when focus is moved to some other window _except_ for the second form. I.e., user should have an opportunity to edit the pattern in the text box and select items from the list at the same time, but when it moves focus away both forms should disappear. How can I achieve this? Tag: Check style for C# Tag: 54838

    - custom drawing menu and MdiList I have a nice custom drawing menu. One of the items is a MdiList and dynamically shows the list of all open MdiChildren. the problem is that the items that identify the mdichildren are not custom drawn. I have no idea how it could be possible to perform also custom drawing for these items. at first glance this does not look like a big problem. after all, the subitems could be drawn as standard menu items. but here comes the the additional problem - the main menu item that has the MdiList item as the subitem is incorrectly drawn because it gets sligthly wrong information about its Bounds (in DrawItemEventArgs). Big thanks for any help, Wiktor Tag: Check style for C# Tag: 54837

    - Problems in Connection pooling: Urgent Hello All, My windows application has a form that needs to display fresh data to the user at short intervals (say every 10 seconds). For this purpose, I have included a timer. On every timer tick, I perform the database related operations to display the result to the user. Note: Multiple instances of my application will be running at the same time and hence the timer running in each instance and initiation database operations. With this approach, I started receiving errors like: Connection timed out. The connection pool has reached its maximum size because every request to the database opened and closed a connection. I changed the approach to: Creating a single connection for the entire form so that all operations use the same open connection. The connection is closed when the form closes. Even then, I now get the following type of errors: a) 8/11/2003 3:21:40 PM SqlUtility Execute Error: Transaction (Process ID 73) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.

    - two-way databinding radio buttons on a windows form? Hi, How do I get the data in the dataset to update when the radio buttons change? Do I need to add code for this, or shouldn't it happen automatically? Strangely, I have a situation where the radio buttons update the dataset when they get set, but not when they get unset - so all the fields in the ds end up with true values - which cause problems when the form refreshes the data. So I isolated the code in a mini sample and this doesn't update the datasets at all... Thanks! Heidi Tag: Check style for C# Tag: 54825

    - Detecting DragDrop target when dropped into Explorer I have an application which i need to allow a user to perform drag & drop of a "virtual file" into explorer. Upon dropping the file into explorer, my app would create a blank file at the location and begin downloading data into it. I can get the app to create an empty file for use with the DoDragDrop(), which essentially moves a blank file (e.g. "%TempFolder%\foo.txt") into the proper destination, but there doesn't appear to be any method of retrieving the location of the FileDrop where explorer has moved this file to.

    - ComboBox : display different string than the selected list item What I'm trying to do : - Add a form to a new project - Add a comboBox to the form with DropDownStyle = DropDown - In form load : ComboBox1.Items.Add("01 - USA") ComboBox1.Items.Add("31 - Holland") ComboBox1.Items.Add("33 - France") ComboBox1.Items.Add("41 - Switzerland") The desired behaviour is that when a user selects a list item only the number is displayed in the textbox part of the comboBox. So if "01 - USA" is selected only "01" should be displayed. Roughly translating the way this would be done in VB6 I tried the following code : Private Sub ComboBox1_SelectionChangeCommitted( _ ByVal sender As Object, ByVal e As System.EventArgs) _ Handles ComboBox1.SelectionChangeCommitted Dim listItemText As String If ComboBox1.SelectedIndex >= 0 Then 'Calculate and store the value we want to display listItemText = ComboBox1.SelectedItem.ToString If listItemText.Length >= 2 Then listItemText = listItemText.Substring(0, 2) End If 'Cancel the selection ComboBox1.SelectedIndex = -1 'Update the textbox part ComboBox1.Text = listItemText End If End Sub However this doesn't work. I've also tried experimenting with the SelectedValueChanged, SelectedIndexChanged and TextChanged events, with no better results. It seems that changing the selectedIndex in any of these routines always cancels out changes made via the text property, whatever the order the operations are carried out in. I've finally resorted to using a timer to update ComboBox1.Text after all these events have finished firing, but it's a very shoddy solution. Surely there must be a way to do this properly?

    - How to sync combo's selected item to the field's value of the current record I'm running win2k and VB.NET (.net 1.1) I have a data entry form and one of the fields is a combo who's datasource is a dataview. The dataview has 2 columns, an ID column - integer, and a name column - string. The form is not databound so the form gets populated with data for the selected reocord via values from a business class. When the use selects an item from this combo's dropdown list, it writes the ID value to the business class, and desplays the name value in the combo.text property. When I navigate to a different record, the ID value changes for this field. How can i get the combo to syncronize to this ID value, or at least set the combo's text to the correct Name? Only the ID values are persited in the business class and not the name values. In MS Access and some 3rd party combos for VB6 all you had to do was set the combo's value to the ID and it automaticly scrolled to the correct item in the dropdown.

    - How to make Win32 controls transparent? Hi, I found that checkbox, label and groupbox have painting problem with their background. I create simple frame with background picture and add checkbox, label and groupbox on it. I set transparent background on controls to see whole picture. Yes, it works. But, if I set controls style to System (to get correct XP Visual Style): checkbox and label background lost transparency!!! groupbox doesn't repaint background (group box is like window throw the frame) So, I think that these three controls in not implemented correctly in .NET. So I start to implement my own Win32 controls. I create the "static" control (label is based on it). But the problem is the same: "static" control is not transparent. So, question is: "How to make Win32 controls transparent?" I think, that it could be done successfuly, because checkbox and radiobutton is the same Win32 class, and radiobutton is painted correctly, but checkbox is not. Thanks for any advice.

    - Shared properties across instances I have a console app running that references an Class Library. The console app runs fine, but I want to be able to run a windows form that will let me poll properties of the Class and reset them. As my console is running, it checks these properties, if one of the properties gets set, then my console app knows that it is supposed to do something, like shut down. I have setup a Shared property in my class: Private Shared sTest As Integer Public Shared Property Test() As Integer Get Return sTest End Get Set(ByVal Value As Integer) sTest = Value End Set End Property As I understood it, Shared properties are available to all INSTANCES of a class. Granted that the Windows form is probably a different process than the Console...is there anyway to create a truley shared property across all instances in all processes? IS there another way to do this?

    - How do I enable Add button in custom collection editor? Hi all. I am developing PropertyGrid runtime support for a custom class. One of my attributes in this class is an ArrayList that holds instances of another custom class. I have derived a custom collection editor for this list attribute. When this collection editor is invoked, it does display the correct caption which I assume means it knows the type of objects it is managing. My problem is the Add/Remove buttons are still disabled. From all the research I have done, I believe it is necessary for me to derive this custom collection editor because I am not working with a collection that provides access to an Item attribute for type discovery, right? I have no further enhancements that need to be made to this collection editor, so do I need to be overriding the EditValue method? If so, what should my implementation of EditValue be doing? Also, I do not have a custom TypeConverter written for the EmbeddedObject type. Is this a problem? If anyone out there can help me, I would be more than grateful. As it sits right now, I am as clueless as top management at a software design conference when it comes to collection editors. MSDN is of no help. There are a few article for the picking out there, but none explain the inner workings of the CollectionEditor in any detail. If anyone can point be to some good articles, I would love to see them. I feel like if I could better understand the CollectionEditor class, I might not be as clueless when trying to use them in real world scenarios. Thanks in advance!

    - Unable to delete controls. Hi, For some reason I appear to have lost the ability to delete controls in the designer (VS.net 2003) When I right click on any control all the options are blanked out apart from 'View Code' at the top. The Del key doesn't work either. I can still drag controls around the form but deleting them is impossible. I don't really want to go hack out all the definitions from the code... Any ideas? Thanks, Russ Tag: Check style for C# Tag: 54702

    - Form, CancelButton, Escape, prevent Form close Hi, I have a form that has a Close button. I set this close button to be the CancelButton for my form. When the close button is pressed, if there have been any changes made to the form, I popup a MessageBox asking the user if they wish to save their changes, using the YesNoCancel message buttons. If the user hits cancel obviously I do not want to close the form. If the user hits close I call Close on the form. This works fine for when the user clicks the close button, but when they hit escape the form closes whether they hit cancel and I call Close or not. How can I get around this? I've pasted code sample below. Thanks, Adam private void bClose_Click(object sender, System.EventArgs e) { FormClose(); } protected virtual void FormClose() { bool close = true; if (myDataPanel.HasChanges()) { DialogResult dr = UIHelperController.Instance.ShowQuestionMessageBox(this,"Changes Made","Changes have been made to this panel. Would you like to save these changes before closing?",MessageBoxButtons.YesNoCancel); switch (dr) { case DialogResult.Yes: close = myDataPanel.Write(); break; case DialogResult.No: close = true; break; case DialogResult.Cancel: close = false; break; } } if (close) { Close(); } } Tag: Check style for C# Tag: 54701

    - System.Threading.ThreadStateException I have a form with a grid. When a user selects some text in the Grid and presses Ctrl-C to copy the text, .NET throws an Exception with the description: "The current thread must set to Single Thread Apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it." However, I already have System::Threading::Thread::CurrentThread->ApartmentState = System::Threading::ApartmentState::STA; in my _tWinMain.

    - Is there a simple way to change the DateTimePicker style. It looks sloppy. I want to use the DateTimePicker, so the user can pick the date from the calendar. Is there a way to choose a different calendar style? I see that I can change some colors, but what I do not like most is the red kind-of circle that circles the current date. The control looks sloppy and non-professional. Is there a simple way to clean it up? Thanks... Tag: Check style for C# Tag: 54697

    - How-to create user control replacing main application form Hello all, I'm wading my way into .net by writing some custom controls. I would like to provide a parent class to these controls to give them easy access to common information. Initially tried this as a panel, but find that I can't drop non-visual components onto panels (they fall through to the main form). So now I am wondering is it possible to override the main application form with a user-authored form? I tried to do this by inheriting from System.Windows.Forms.Form, but when I instantiate such a control in the IDE, it actually appears to spawn a new thread consisting of an independent windows form which can't be accessed using the normal designer interface. Unrelated question - anyone know of a good online reference on Attributes? Thanks, Markus Tag: Check style for C# Tag: 54692

    - Simple problem with the AxWebBrowser control Hello, I am using a AxWebBrowser control in a VB.net windows form. In the form, I also have a TextBox where the user enters the URL he would like to navigate to. I want the TextBox to change it's display (to reflect the new page address) when the user clicks on an hyperlink on the web page (like in Internet Explorer). I have been looking at the events and methods of the AxWebBrowser object, and I can't find it! Any help on this would be very appreciated. thanks, Ross Tag: Check style for C# Tag: 54690

    - Using Control.Invoke I want to programatically invoke a KeyDown event to a control that has the focus. Maybe you guys know a better way to do this anyway. In my MainMenu I have an Edit sub-menu that has Copy and Paste items. Each of these menu items I setup to use the Shortcut keys Ctrl+C and Ctrl+V. However, I want the Form window that is handling the main menu messages to be stupid about it and just notify the ActiveControl of a KeyDown event to let the controls handle copying to the Clipboard themselves. Going with this scenario how, in C#, do I invoke a KeyDown event to another control programatically? Or is there a better way to notify the ActiveControl? I've tried the following, but I get a compiler error. ActiveControl.Invoke( KeyDown, this, new KeyEventArgs (Keys.Control|Keys.C)); Thanks for your help, Aaron Tag: Check style for C# Tag: 54686

For our C# project we have some code design guide lines as to whether barces
are in place and whethere lines are upto

We have FxCop and its working great but that is for checking binaries and
not for checking source code styles.

We are looking something of the sort of CheckStyle and PMD of java world.
