    - Backup database from code: Access denied on user specific directories I want to backup a sql express database from my windows forms C# code. I can do this by running a sql command "BACKUP DATABASE TO..." (or using SMO) and I can save the backup file to any subdirectories of C:. The problem I have is that I want the user to be able to save the backup file to any location, including C:\...documents and settingsm\my documents... However, the file access for these directories (user specific) are more limited and the BACKUP DATABASE command fails due to Access Denied. Should I mess with the ACL to grant NETWORK SERVICE read/write permissions on the directory they want to save to? I am not very comfortable doing this as I don't like the idea of changing the ACL security on someone's system. The simplest solution is for me to restrict where they can save the backup file (to subdirectory of C:\), but if there are any other solutions, I'd like to hear them. Thanks.

    - using DateTimePicker with null entries Hi I have a windows form that includes a datetimepicker control. The form gets its data from a ASP Web service. The database field that supplies the data to the DTP control can have null entries. Unfortunately the DTP control either displays the correct date when there is data in the field but when there is no data (null), it displays todays date. Is there any way of geting the DTP control to display nothing when there is no entry? Hoping somebody can help. Kind regards Ross Petersen Tag: Form proprties - Is it a bug or .. ? Tag: 111652

    - Problems with the Windows Forms Designer Hello all, I've been working on a project in VC++.NET 2005 which contains a form with a custom control. Today when I opened the project, the designer complained: Could not find type 'VIAWorkspace.Toolbar'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built. Now, I've rebuilt the solution. When it runs the toolbar appears as I expect it to, but the IDE refuses to correct the problem. How can I fix this? Evan Tag: Form proprties - Is it a bug or .. ? Tag: 111647

When someone enters the editing of the node text, TreeView process the Ctrl+C and puts the marked text into clipboard.

    - combobox with command items Hi I want to have a combobox with some commands in it and a data source. Basically the list should look like command1 command2 ----------- data1 data2 data3 To solve this problem i decided to derive my own combo box form standard ComboBox control. I exposed 2 properties in this class 1) List of CommandItems 2) ArrayList as data source Now i tried to merge these 2 sources as 1 source and set the data source for the base class. I also set the DrawMode to OwnerDrawVariable and subscribed to DrawItem event. I thought that i would be able to draw the items on my own. This way i am able to insert the separator between command items and the data items. However when i do this i am unable to set the DisplayMember of the combobox it doesn't work at all. Additionaly i also am thinking even if i am able to do that it has to be different for data list and the command list. Any ideas on how can i achieve this ? ~Abhishek Tag: Form proprties - Is it a bug or .. ? Tag: 111617

    - Anchoring issue. Lets say I have a control at the bottom of my form and I have it set to anchor Top, Bottom, Left, Right That does exactly what I want it to do.... Ok here's my issue. I have recently taken the contents from that form and placed them on a user control instead. I set the output type to dll for the project with the user control. I implement my own interface, compile, and then place the dll in a plugins directory of my host app. My host app then rakes the directory, finds any types that implement the interface and when it finds one it loads that user control as a new tab in the host apps tab control. The interface requires that there be an init function. The host always runs this when it finds the dll and passes in DB information. Inside the init function I have tried to also set the user controls anchor like so: this.Anchor = ((System.Windows.Forms.AnchorStyles) ((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); I'm not sure if the syntax is 100% in this posting because I've commented and uncommented and recommented so many times trying different combinations. Just know that I'm setting it the same as if I were using the designer. Top, Bottom, Left, Right... Now the Host app has a tab control as I've already stated. It has it's anchor set to Top, Bottom, Left, Right so that it expands if the form does. Now when it loads, everything runs off the screen. So let me lay out the context more clearly: Host Form - Tab control - Anchor Top, Bottom, Left, Right - User Control found at runtime - Anchor Top, Bottom, Left, Right - Control - anchro Top, Bottom, Left, Right I can create the same app with just a tab control and place the end control right on a new tab page and anchor it. That works as expected and everything expands as it should. but once I put the control on a user control and then load that dynamically into the tab control setting it's anchor, everything expands way off to the right and bottom.

    - How can I use C++ codes with .NET Framework codes? I would be pleased if someone gives me a general idea; how I am going to do this. I am using visual C++ .NET 2003. I made a simple program using conventional C++ code. This program accepts data from the user, does some calculations and outputs the result back to the user using the console. Now, I want to use the .NET Framework to interact with the user through Forms, Dialog Boxes and Controls. I managed to create all the forms that I need to interact with the user and they work very well together. But, now I want to use the first program that I made from conventional C++ with .NET Framework. In other words I want the user to input data (through Forms and controls) and then I want to manipulate the data mathematically (using the conventional C++ code) and out put the result (through other Forms and controls). So my question is how can I use the conventional C++ code with the managed code and which file(s) am I going to use? For example, I have the following files:- References: .. .. Source Files: AssemblyInfo.cpp Form1.cpp Form2.cpp Form3.cpp Stdafx.cpp Header Files: Form1.h Form2.h Form3.h Resource.h Stdafx.h Resource Files: .. .. ..

    - How to tell if file is text based I want my application to load any file that is text based (php, txt, rtf, asp, etc) - - just not any binary file In the Open file dialog, that's easy, but I want users to be able to load the files by drag/drop - - so therefore, I will need to check for the types of files. I could go through the different filetypes if FILENAME.endswith(".txt"), etc, but that would end up being pretty ridiculous How can I check the file, as it comes in, as to whether it's text based or binary?

    - MaskedTextBox with negative double numbers I am trying to use a MaskedTexBox to accept positive and negative DECIMAL/DOUBLE numbers. I tried by setting the Mask to a custom mask of "0000.00" but that allows for no negatives. I tried with "+00000.00" but the same problem. According to the documentation there is a design variable ValidatingType. But at least in VC# Express 2005 such property does not appear in the list of properties at design time! So what I did was to manually set the ValidatingType to typeof(double) in the constructor. But the same problem persists. Any ideas? or was this some great half-baked idea?

    - BeginInvoke failing when executed in a form that was created in a worker thread... I previously posted this in the VB.General forum, but thought that this one might be a better place for it...sorry about the double post. I have created a simple form with code that looks like this: '****************************************************************************************** Public Class FEventRaiser Inherits System.Windows.Forms.Form Event MyEvent(ByVal eventName as string) Private Delegate Sub EventRaiserDelegate(ByVal eventName As String) Public Sub New() ...other code removed for clarity. 'Force the creation of the form's handle. While Not IsHandleCreated Dim temp As IntPtr = Handle End While End Sub Public Sub RaiseAnEvent(ByVal eventName As String) If Me.InvokeRequired Then 'Call made on thread different from the thread this form was created on...BeginInvoke. Me.BeginInvoke(New EventRaiserDelegate(AddressOf RaiseAnEvent), New Object() {eventName}) Else 'Call made on same thread as this form was created on...raise the event. RaiseEvent MyEvent(eventName) End If End Sub End Class '****************************************************************************************** If I create an instance of this form from within another form, and then make calls to 'MyRaiseEvent' from within a threaded timer, it works as I would expect: Public Class Form1 Inherits System.Windows.Forms.Form ... Private WithEvents mEventRaiser as FEventRaiser Private WithEvents mTimer as System.Timers.Timer ... mEventRaiser = New FEventRaiser mTimer = New System.Timers.Timer(1000) mTimer.Enabled = True ... Private Sub mEventRaiser_MyEvent(ByVal eventName As String) Handles mEventRaiser.MyEvent 'This event is handled on the same thread that this form's message pump is running on. Debug.WriteLine("Event processed on thread: " & AppDomain.GetCurrentThreadId) End Sub Private Sub mTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles mTimer.Elapsed mEventRaiser.RaiseAnEvent("This Works") End Sub End Class Even though the timer event handler is firing on different thread IDs than the main thread, the call to the mEventRaiser.RaiseAnEvent ends up performing the necessary BeginInvoke, which results in mEventRaiser raising an event back on the main thread...this is the behaviour I would expect (and want). If I then modify this code somewhat so that the mEventRaiser is actually created once in the timer event handler, then it all stops working (please ignore the hack method I used for instantiating the CEventRaiser object...the real way it's done is in a worker thread created at the same time the threaded timer is created). Here's the new timer event handler: Private Sub mTimer_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles mTimer.Elapsed If mEventRaiser Is Nothing Then 'One-time creation of event raiser. It used to be created in the main thread, but now it's created in 'the context of the timer's first-time-firing thread. mEventRaiser = New FEventRaiser End If 'As before...ask event raiser to raise event. This no longer works. The BeginInvoke in the RaiseAnEvent call 'does nothing. mEventRaiser.RaiseAnEvent("This doesn't Work") End Sub End Class I hope you can makes sense of this code, and any insight you can provide would be greatly appreciated.

    - weird problem with ComboBox - DataSource contains data, but the Items collection stays empty I created a custom control which simply is a data-bound ComboBox. It has a custom property that causes an ArrayList of KeyValuePair elements to be passed to the DataSource property. It also sets the DisplayMember and ValueMember properties. What's weird, is the fact that my control sometimes works fine and sometimes it doesn't. I have no idea why, but when I put on Form1 everything is fine, while on Form2 the Items collection stays empty, although the DataSource property contains data and it is exactly the same data (pulled from the database in the same way) that I use in case of Form1.

    - decimal separator, regional settings Hello there! Here is my problem, in the simplest scenario: - an Access 2000 format database (created with Access 2003) - a simple table that contains one single field defined as Number, Decimal, 18,2 - VS2005 standard, C# - a data source / dataset that cotains that simple Access table - a DataGridView, created by drag and drop, with all the helper objects (adapter, navigator etc) that edits that simple table - WinXPSP2 with ***Regional Options in Control Panel set to Romanian*** , with no other customization And here's the problem: what magic do I have to do to enter decimal numbers in that grid and save them in the database? Because as long as I type in 1,23 (given that the decimal separator in Romanian Regional Options is the comma), the grid displays it correctly, I can save it to the daabase, but when I reload the data by reopening the form, my number is 123 (and it really IS 123 in the database!).

    - Settings for Windows Service I have a requirement to create a windows service application that will need have settings (e.g. list values, connection settings, etc.) stored externally (i.e. not hard coded). To allow administrators to manage the settings I'll be creating a windows form application, very simple one, that will run in the system tray and when a setting needs to change (once in a blue moon) the administrator can right click and change/add a setting through a dialog window. The dialog will give the user the ability to restart the service so the settings can be read by the service at start up again. Here is my question. To store the settings i'm inclined to add an app.config to the windows service and have the windows form app read/save settings to the config file.

Everything seems to be working fine at run time but at at design time, the designer cannot display the derived control unless I place declarations for the various form controls in the designer code. See the code below for an example. Note that if I remove the comment from the line 'Friend Shadows Label1 As Label in the derived control, the designer is happy and works fine but of course this effectively breaks the link between the controls and their handlers in the base class. If I retain the comment, the designer gives the error "The variable 'Label1' is either undeclared or was never assigned." How do I overcome this? Is there a way that I can fool the designer without commenting/uncommenting code? Am I simply doing this all wrong? Bill E.

    - seems pretty simple but.. maybe not. (if this is the wrong ng, plz point me to the right one).. i'm trying to add simple text find capability to a tool at work and am having problems. i want it to work just like Notepad - that is the Find dialog remains in focus after clicking the Find button and at the same time, the found text in the edit control is hilited and remains so even while the edit control does not have focus. i can get the text to hilite alright but it's only visible if i set focus to the edit control just after calling the Find method. this is totally opposite of what Notepad is doing. does anybody have any idea how Notepad accomplishes this?

    - Running ReportViewer report in another thread using BackgroundWorker Hi: I'm trying to give user something to look at while a ReportViewer based report runs. It takes a while because app connects to data over the internet. Problem is report locks-ups when launched in DoWork event. Backgoundworker seem to work with non-visual stuff. Is the problem because report renders in a Window? A simpler approach is just pop-up a nonmodal form and release after report finishes. That works, but controls look transaparent.

    - Application type question Hi My vb winform app updates between site sql server and in house access db. The app needs to always run and is in the start-up of client's sbs 2003 (windows 2003) server. Problem is if client restart server and forget to login the app does not run. I am resisting doing it as a service as a service has some development restriction as well as installation complications making it difficult to debug too among other things. What is the best solution to this situation? Should I go the service route? In which case is there an easy way to convert a winform app (with a visible form - for monitoring purpose) to service type app? Thanks Regards Tag: Form proprties - Is it a bug or .. ? Tag: 111512

    - Dynamic Control Example for 2.0? Could someone provide a quick example for .NET 2.0 WinForms of how to dynamically add a control "btnDynamic" to a form when button "btnStandard" is clicked. I don't want to hardcode "btnDynamic" to the form and make it simply visible, I don't want it to exist at runtime until "btnStandard" is clicked, but when "btnDynamic" is created and instantiated, it participates in the form's full event cycle and has its own click event and etc. Thanks.

    - ListView CheckBoxes hello everybody, I had a problem with a ListView - Object.. I want to list some stuff in a ListView, I created some columns and startet to fill it. In the properties of the ListView I set "VirtualMode" to "true" .. so I could define the values for the columns. I want to select each entry by an checkbox, but the ListView didn't draw the checkbox. If I set the ListViewItem.Checked = true, then I will see the Checkboxes .. but if I don't set it to true, then there will be only the entries without the Checkboxes. I tried the "DrawMode=Own" .. but the result is the same.. could anyone help me? thanks a lot, Ben Tag: Form proprties - Is it a bug or .. ? Tag: 111510

Hi Tamer,

>From MSDN:
"This property is not supported on child controls whose
RightToLeftLayout property is true."

Sorry =).
