    - memory not being released Hello all, I have a winforms app running on framework v2.0.50727 which isn't not releasing memory back to the OS after closing forms. Simple forms (a list + button) or complex ones (tabs, lots of text boxes, third party masked edit control) behave the same way, Every time is instantiated it allocates memory which never gets released. The code sequence is Dim frCustomer As New frmCustomer .. custom code to populate form ... frCustomer.ShowDialog() frCustomer.Dispose() If Not frCustomerIs Nothing Then frCustomer= Nothing Where should I start troubleshooting? What am I doing wrong. Thanks a million, Gigel Tag: Context menu depending on panel Tag: 112683

    - Difficult issue with ITypedList and subclasses I am employing ITypedList to expose properties of contained classes and am having trouble with properties nested a few levels down. My class structure looks something like this: EmployeeCollection ' A collection of Employee objects, Implements ITypedList Employee ' Decorated with an attribute that points to a CustomTypeDescriptor. This CustomTypeDescriptor class exposes properties of an Activity class that is contained in Employee. Activity ' A Simple class, also decorated with an attribute that points to a CustomTypeDescriptor-derived class. This class exposes properties of the Attribute class, contained by Activity. Attribute 'A simple class contained by Activity. I bind a DataGridView to the EmployeeCollection class. I've been successful in using ITypedList when going one level deep, but when I cannot seem to expose the properties of the Attribute class at the highest level. In other words, I want to display properties of Employee, Activity, and Attribute in the datagridview, but cannot see below the Activity class's properties. Any insights would be appreciated. P.S. Sorry if this message posts several times. Not sure why this happens. Tag: Context menu depending on panel Tag: 112682

    - RDP ActiveX control in winform i'm writing a simple c# program to start an RDP session from a windows form. everything works fine except i can not determine how to cause the program to allow me to execute a specific application on connection: try { rdpSession.Server = myServer; rdpSession.UserName = myUserName; rdpSession.AdvancedSettings2.ClearTextPassword = "************"; rdpSession.Domain = "myDomain"; rdpSession.AdvancedSettings2.ConnectToServerConsole = true; if (rdpSession.SecuredSettingsEnabled >= 0 ) { rdpSession.SecuredSettings.StartProgram = "c:\\Windows\\notepad.exe"; rdpSession.SecuredSettings.WorkDir = "c:\\temp"; } else { MessageBox.Show("Can't access the secured setting (startprogram)"); } rdpSession.Connect(); } my understanding from the documentation of the control is that: These restricted properties are accessed using the IMsTscSecuredSettings interface and the IMsRdpClientSecuredSettings interface, and are available in the following Internet Explorer URL security zones: My Computer Local Intranet Trusted Sites They are disabled in these zones: Internet Restricted Sites when i examine the value at SecuredSettingsEnabled in the debugger it is always -1 and therefore skips executing the startup application. [it does start a desktop session in which i can execute the application - which seems to circumvent the intended "security feature"??? - but perhaps i am thinking wrongly???] is there a way to cause the application to evaluate what Internet Explorer URL security zones it is running in - the concept seems inappropriate and inapplicable to running my executable? but again perhaps i am not thinking correctly?

    - Do I need to call base.WndProc in this scenario? Hi all, I have been working around the notorious 'Automatically scroll selected control into view' 'feature' of the .net framework using the following code. Now I read that if I do not call base.WndProc, this can cause problems like 'Error creating Window Handle' and I am getting this error. My code is as below. How do I modify it to prevent the WM_SETFOCUS from being handled but still call base.WndProc()? Thanks! private const int WM_SETFOCUS = 0x0007; protected override void WndProc(ref Message m) { // Listen for operating system messages. // The WM_SETFOCUS message is sent to a window after it has gained the keyboard focus. if (m.Msg != WM_SETFOCUS) { base.WndProc(ref m); } } Tag: Context menu depending on panel Tag: 112676

    - Multiple AddHandler for multiple Controls on a form Hello all, We have a bit of a problem. We have a form where we have to add controls dynamically during runtime. That part is quite simple. Now, we have to add a ButtonClick event for each of the controls. That's where it becoms tricky. Here is the bit of code we use: ------------------------------------------------------------------------------------- TextControl = New Asd.ControlLibrary.AsdTextControl Me.TextControl.BackColor = System.Drawing.Color.Transparent ....additional properties setup If CheckStoredProcedure <> "" Then Me.TextControl.CheckStoredProcedure = CheckStoredProcedure Me.TextControl.ButtonBook = True Me.TextControl.ErrrorProvider = True Me.TextControl.CheckRequired = True End If AddHandler TextControl.ButtonBookClick, AddressOf TextControl_ButtonBook Me.Controls.Add(TextControl) -------------------------------------------------------------------------------------- Now, everything works fine and each control acts as a separate control, but the TextControl_ButtonBook fires only for the very last created control. I have tried adding 'sender' parameter to the procedure but the addressof won't accept it. Any help and/or insight is much appreciated. Thanks in advance.

    - Programmatically changing the size of a textbox I have a textbox that is multiline but I only want to show one line at the start until that line is filled in. I am going to use the textchanged event to check the length of the text in the field. If the length of the text is greater than the length of the field, I am going to change the height of the textbox to show another line and when that is filled I am going to add a new line etc etc. My question is what is the easiest way to move all the controls below this textbox down?

    - Help. Problem with MaskedTextBox in DataGridView control Hi, I am adding a MaskedTextBox control to a datagridcontrol. So far, I can see the masked value, but when I start the application up, the maskedtextbox cell is blank. When I select it, I can see the masked value "00000-000-00000-0". I change the value and click a readonly cell. The maskedtextbox values goes blank. When I click on the cell again, the value reappears on selection event. However, When I click on a non readonly cell, the maskedtextbox value totally disappear. At startup, the masked value 00000-000-00000-0 is invisible until I select the value. Here is my code.

    - DataGridView ComboBoxColumn I am trying to use the DataGridView to accomplish a certain task. Here is my scenario: I have a datasource that has a Model/Make relationship. It can be likened to a user filling in what cars they own. So they add a new row and select the Mae of their car from a combobox. Then they can select the model from another combobox in the same grid. The model combobox only contains possible models for the make selected. In turn, if they go back to that row later and select a different make, the model choices should now correspond to the newly selected make. Everything else on my winform is bound so, for consistency sake, I am trying to keep all this databound too. Any ideas, sample code, etc??? For what it is worth, I am aware that one can create a custom datagridview combox column. I have looked at this briefly and it is hard for me to determine what events I would need to override in order to get my desired functionality. Any ideas? Thanks in advanced!

    - App.config - Break up into multiple files? Hi, I have a legacy application which I can't change which has a _huge_ app.config file. I want to break it up into several smaller files and use !ENTITY to include them into the main app.config file; <!ENTITY foo SYSTEM="../../foo.config"> <foo> &foo; </foo> Suffice to say, this doesn't work. I get 'reference to undeclared entity 'foo' line 2 position 6'. It looks like the section handler is reading <foo> as a totally seperate XML document ('line 2' is the giveaway), which of course, doesn't have the <!ENTITY> bit. Does anyone know if it's possible to break up app.config into seperate files and include them like this (or any other way!)? It would seem not. Many thanks Paul.

    - Ignoring all key events in whole application Hi all, I've been struggling with this problem for quite a while, and have searched the internet many times, and tried many of the ideas which that turned up - but haven't managed to get this to work! Basically, my application receives serial messages from another system. If a certain field is set to true in the status message then the application must not let the user do anything using the keyboard. As in the application must ignore all key events in all possible ways - none of the code in any KeyUp, KeyDown or KeyPress events should execute, and all controls should ignore keys (ie. if the focus is on a text box, then the text box must not allow the user to add any text, and the same for any other controls). When the field is changes back to false then the application should return to normal. Basically, what I am looking for is a way to stop the application getting any key events whatsoever. Is this possible? If so, what is the best (or only?) way to do it? I have struggled with such things as e->SupressKeyPress (which didn't seem to work at all), PreFilterMessage, PreProcessMessage and haven't managed to get anything to work! If anyone has any ideas at all, I would be very grateful to hear them! Cheers, Robin Tag: Context menu depending on panel Tag: 112653

    - Set focus to a Desktop's child I have created a command prompt window (ruinning cmd.exe with the Process class) and made it child of Desktop (or i attached it) using the APIs FindWindow and SetParent, this way: SetParent (MyCmdProcess.MainWindowHandle, FindWindow("ProgMan", null)); This works fine! Now, I want to create a little app to, when it is executed, it shows the desktop (i already do this) and SET THE FOCUS TO THE CHILD COMMAND PROMPT WINDOW (that is not a normal form). How can I do this? Notes: 1) FindWindow (null, "PID_Terminal") returns null, maybe because it is a child now. 2) After I turn the command prompt a desktop's child, MyCmdProcess.MainWindowTitle is set to a empty string ("").

    - Same application in dual monitor Actually the thing is i am devoloping a windows application, which will be displayed in multiple monitors. i have one single exe, which will be displayed in 2 monitors for example. In cloning mode (windows display setting) both the screen will display the same content. (eg. form1 will be displayed in screen1 and screen 2, since both are same, check box click on screen 1 will show check box click on screen2). Now in my case i want to show 2 different forms of same exe in screen1 and screen 2. (eg. form1 in screen1 and form4 in screen2). (1) first how do i do that? or is there any alternative ways? (2) If i click a check box on form1(screen1), although the screen2 display form4 , the check box on form1 in screen 2 should be checked. how do i achieve this functionality. There are actually 2 touch panels connected to the system. And both the touch panels are interactive and shows the same(one main part of the application). In the application for example there are 2 forms in which through one form it controls temperature of the room and through other form it controls room light. But since this is one exe at a time only one operation will happen.(for eg. if an operation in form1 hangs the system(screen1), system will be hanged in screen2 too even it doent show form1) In extended display, can we show same application, interactive in both the screens? in which the screen can show same form or different form? right now i am thinking to create 2 objects on form1 at runtime and attach to the screen boundaries. but how we communicate an event in one object to another object?

    - Dynamic controls and postback. I have to modify existing code : Basically, it implemnts tabbed forms. On the pageLoad, the code creates the two selection controls, plus kind of page depending of selected control. On selected control_click, do a page redirect to itself, putting in the url the new selected control. This somewhat works, but when the user clicks on another tab, there is a first rendering of the page with the initial page (page_load + control_click) , then a redirect, then a new page_load with the new controls displayed. How can I ameliorate the round trip time, by rendering the new page in the control_click, and not doing a redirect. I have tried it, but its says invalid view state. So I disabled view state for the tabbed page (it is in a table cell) , but it keep saying control ID already used. (None of the dynamic controls created have ID). Is there a better way to do tabbed forms ? NB asp net 2.0. Thanks. François. Tag: Context menu depending on panel Tag: 112616

    - DateTimePicker - how to show nothing when user has not specified a date? Is there some way to have the DateTimePicker display nothing? I came up with a hack but I was hoping that there was a less offensive method than the horrid little code snippet that fell out of my fingers when I wasn't paying attention. Here's why I need to have the date time picker be able to not display date information. My client wants to display nothing if the underlying data model does not have a datetime value. If the user sets focus in the control then the client wants the date time picker to immediately light up with a default date time. If the user leaves the control without entering a value then it goes blank again. Otherwise, it hangs on to the user's entered value from then on. Here's the hack. When the form is first shown, display the date time picker if the data model's date time is valid. Otherwise, hide the date time picker and display a text box where the date time picker would have been. When text box receives focus, hide the text box, show the date time picker and transfer the focus to the date time picker. On leaving the date time picker, hide the date time picker and display the text box if the user did not enter in a value. If the user did specify a value then leave the date time picker visible and the text box remains hidden. Most of this horrid little code snippet works just fine (or at least as well as one might hope for). However, there is a problem with the text box's tab index. It is set with the same value as the date time picker's but it insists on being someplace very different in the tabbing order. Why is this and how can I fix it? A second little puzzle has to do with the date time picker's Leave event handler being called in response to calling dateTimePicker.Focus(). Why is the Leave event being called? How do I stop this? -- Richard Lewis Haggard General: www.Haggard-And-Associates.com Please come visit here for a couple thousand good giggles!: www.haggard-and-associates.com/Humor/humor.htm Tag: Context menu depending on panel Tag: 112609

    - General question about deployment strategies for Dot Net 2.0 Winfo I work in a large corporation with a large amount of legacy code. It is intended to eventually replace the legacy code with Dot Net 2.0 apps. They have a legacy update distribution system that they are rather 'fond' of. (i.e. it isn't going anywhere anytime soon.) It seems to be mostly a copying system, possibly using xcopy. Every machine in the system gets its application updates this way. There is a reluctance to use ClickOnce or the Windows installer. Frankly these applications are for internal use only, the security requirements are not that strict, and the code is not that complicated. Given that, tell me if my assumptions are correct: In general and at a minimum, when compiling a VB Winforms app, all necessary reference dlls and resources are copied into the bin directory. Assuming that the target machine has Dot Net 2.0, all that is needed is to copy the bin directory to the target machine and it should run. (As yet there is no need for shared assemblies or other complications.) Tag: Context menu depending on panel Tag: 112607

To make it easier to reproduce I've simplified: 1) one group box with a combobox and a textbox and the combo has the focus; 2) the user first selects and item from combobox and the focus passes to textbox; 3) user doubleclicks on textbox and the current groupbox which fires this: a) current groupbox visible status changes to false; b) based on the information the user selected on the combobox, a DatagridView is displayed in another groupbox, changing focus to it; c) and now, this is the problem, if the user uses the mouse roller then combobox, in the invisible groupbox, SelectedItem is changed and I can't explain why. If the first groupbox stills visible, the problem does not occurs, but that is not an aceptable solution, because the form remains with too much information. I hope my problem has become clear. Thanks. João. Tag: Context menu depending on panel Tag: 112605

    - Forcing a datetime format for all users all over the world Environment : framework 1.1, winforms, webservices, sql server 2000 Architecture of the application : database is hosted behind the webserver. Client winforms application is installed on the client machine and webservice are used to transfer the data from the client exe to the database over the internet. Database\ webserver server is running on GMT time where as the client machines can be running on any time zone and any part of the world. Ado.Net Datasets are used to transfer the data between the client machine to the database over the webservice. My application has 50 forms having thrid party grid controls used all over. since it is gong to be used in all different countries, i want to do force the datetime to have a specific format which is 'dd-mmm-yy hh:mm:ss' for all culture. One way to do it is to hardcode this format in every form's control but i think there might be a better way which is using the cultureinfo object, is there any way to force this object to show a specific format for datetime so that if it is set in one place (like the start of the application) all controls in all forms will show this datetime format. If anybody's got a piece of code, please show me the link. thanks Tag: Context menu depending on panel Tag: 112603

    - Problems creating a custom column within a DataGrid We're doing a project using VS2005. A coworker needs to create a custom column within the old datagrid. (Can't use the new DataGridView for some reason unknown to me.) This column will be a checked list box. I have not worked with the datagrid in some time but I have managed to hack together a test program using leftover code. (The usual techniques. Create a custom tablestyle, add the columns, etc.) The code does work, at least so far as when i click on a particular row, the checklistbox displays and is populated correctly. (The grid itself is bound to pubs.titles. The checkedlistbox is bound to publishers. No real code. Just fill the datasets and display) The problem is this. I believe I am looking at only one instance of the checked list box for the entire grid rather than a separate instance for each row of the grid. Any changes I make in one row are visible in any other row. I realise this is a pretty vague description but what would be some obvious things to check for?

    - Delete controls that are initialized but not added to other controls. Hello, I create a complex UserControl, about 200 sub-controls in it, when I complete it, I found there are many useless controls, e.g: button1, it is initialized, but never be added to any other control as child control, so it is useless. I want to optimize my control by deleting those controls. I am wondering whether I can do it through some automatic tool? Thanks zlf Tag: Context menu depending on panel Tag: 112592

    - Winform App and security issues I have a .Net WinForms app running on a server and the user accesses it through the Citrix Neighborhood. A feature of the app is that it creates an excel spreadsheet file and then the user can choose to save it to their local hard drive. When the app was under VB6, this was not a problem but now under .Net the app hangs when trying to save to the local drive. I tried it and it worked but then I have administrator privileges on the server. What do I need to do to the app so that users who do not have administrator rights on the server can allow the app running on the server under their logins to save the file to their local drives?

    - Problem with ClickOnce Deployment I'm having a problem with a ClickOnce deployment. We have two identical (so far as I know) Windows 2003 SP1 servers. I have successfully published to one of the servers and installed from it. (There is still a slight problem we have not resolved. We have to create a copy of app.config.deploy and rename it <app name>.exe.config.deploy. Still haven't figured this one out but once we do it, it works, no problem.) On the problem server, however, the publishing still works, but when I try to install from the server, I get the following error log.

    - DataTable binding, Column change events, and BindingManagerBase PositionChanged I've assembled a form with numerous controls that bind with different DataTables representing a relational database. The DataTables are arranged hierarchically. To navigate the rows in the DataTables I'm using Prev/Next button events that access the respective DataTable's BindingManagerBase.Position field and modify it. Works _fairly_ well. I've noticed that my DataTable.ColumnChanged event handler (used for validation) fires once for each change the user makes (which is good and expected), and once when navigating to a new row (which is puzzling). For example, with no row edits a click on the Prev or Next button, the ColumnChanged event handler fires. Does this seem accurate, and if so why? -Jamie Tag: Context menu depending on panel Tag: 112580

    - changing columns and data in a listview at runtime I have a executable winforms application I would like to change. I use quite a number of listview controls in my main form. I dump about 15 columns of data into a couple of listviews. This data comes from classes that implement Ienumerable such as the below... I use a method in the main form to update the listviews... s. I want to change this application to Only to show 4 columns of data (new data) Have the ability for the user to choose at a right context menu click of the listview to add up to 19 columns of data And have this data sorted in the list view after choosing the column and sorting QUESTION: Is the correct thing to do to populate the listview with 19 columns of string data and recreate the listview to try to hide the unwanted 15 columns Let the user choose what columns he/she wants in the right context menu and let the listView handle the sort and show only the columns selected -or- Create a new hashtable with 19 columns of data Recreate a new listview in place with the user selected data columns kill the old one and pump in only the data from the sorted and related hashtable -or- Something else?

    - Displaying rich text format in a DataGridView We've all seen search engines where keywords from the query are bolded in the search results. I'm trying to replicate that in a DataGridView. However, it only supports plain text. Is there any easy way to accomplish this? I did run into some stuff on the web about converting RTF to a BMP but, in my experience, it doesn't work well. There's got to be a way to extend the DataGridViewTextBoxCell to support RTF directly. Thanks. Tag: Context menu depending on panel Tag: 112573

    - Problem reading/writing to a config file. A friend handed me a copy of MS Press's 'Programming ADO.Net 2.0'. There is a bit of code on pg 99 regarding config files. I have been trying to write a demo program based on this for my own understanding. The purpose (I thought) was quite simple: to create an editing screen for config strings, to read, write, and update them. Unfortunately, while I can add strings, I can't seem to update them. I keep getting 'configuration is read only' messages. Here's the code for my Save button. Dim setting As ConnectionStringSettings Dim config As Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) Try setting = ConfigurationManager.ConnectionStrings(txtName.Text) If Not setting Is Nothing Then ' An attempt to get around the read-only problem. ConfigurationManager.ConnectionStrings.Remove(txtName.Text) ConfigurationManager.RefreshSection("connectionStrings") config.Save(System.Configuration.ConfigurationSaveMode.Full) config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) End If setting = New ConnectionStringSettings() setting.Name = txtName.Text setting.ConnectionString = txtContent.Text config.ConnectionStrings.ConnectionStrings.Add(setting) ConfigurationManager.RefreshSection("connectionStrings") config.Save(System.Configuration.ConfigurationSaveMode.Full) Catch ex As Exception MsgBox(ex.Message) End Try Tag: Context menu depending on panel Tag: 112572

    - databinding issue Hi, I have a business object I want to use for binding. There are a series of combobox on the form that are populated via a bindingsource which sets the DataSource, DataMember, ValueMemeber. THis populates the combo with available values. Now, I bind all the controls on teh form to my business object. The BO has a property which I set to be bound to the SelectedValue of the combo. The property in question is defined as an enum. It seems like the binding mechanism cannot read/write from the property when defined as an enum. If I change it to Integer, it all works correctly. Does anyone know the cause of this issue? Is there a work around or something I need to do to make this work? Thanks in advance for any assistance you may provide. Tag: Context menu depending on panel Tag: 112561

You can set different menus on different panels using ContextMenu property

Or you can assign menu dynamically in right-click handler using same
property
