    - Strange problem with DataGridView AutoGenerateColumns I have a DGV on a form that is bound to a BindingSource, bound to a business object. The DGV has AutoGenerateColumns = False and I have created the columns I want in the designer. When I make any change to the code behind, even something innocuous like a new line, and then switch back to the designer, it automatically generates the columns in my binding source and adds them to the ones I created manually. Also, I don't see AutoGenerateColumns anywhere in the DGV's property sheet. Am I missing something? I'm using the latest SP. Any ideas? Tag: Help to trap Datagridview cell keypress events...

    - Empty NumericUpDown Hello, I have a small problem ; I have found an alternate solution but I don't like it. The problem is simple, let's take a form, a numericUpDown inside and a button that will show the value of the numericUpDown in a MessageBox (or elsewhere, whatever). Let's say you put '5' in the numericUpDown, click the button, "5", ok. Now, erase the '5' in the numericUpDown, click the button, still "5" but _nothing_ in the numericUpDown. My problem is that I would like to catch when the user erases what's inside the numericUpDown in order to put in the MinimumValue or just display the actual Value. Of course, I don't want it to be ReadOnly. My alternate solution is to use numericUpDown.UpButton() then numericUpDown.DownButton() but as I said, I don't like it. If anyone has encountered the same problem and found a (better) solution, I would like to read it. Thanks, -- neva Tag: Help to trap Datagridview cell keypress events... Tag: 110794

    - Form Editing Events Hi, I'm designing a form and I'd like to know when a control has been edited. I know how to get around this, by putting code behind every control to see if theres a change and then set a flag, but thats a waste of time and a lot of code to write. I can see someone having a much more elegant solution, I just can't work it out. I was thinking of having every control inherit some master control so I can have one peice of code that 'detects' when a change has been made to any field or check box, just not sure how to go about it. Anyone have a nice and simple solution? Thanks, Tag: Help to trap Datagridview cell keypress events... Tag: 110791

    - Total Loss of control in VS.net 2005 code window I'm now consistently having a problem (shortly after SP1), that, heretofore, only happened once in a while. Now, I bring up the code window in VB.Net 2005 - and I loose total control - I type in a letter or two (most of the time, it's only one), and the intellisense seems to think that's all I need - the code window loses focus, sometimes thinking I'm finished, and adds parentheses at the end. Then, no matter what, I click in the code window, and I can't type in but 1 letter - then it does it again. When it first started happening, I could just shut down VS.Net - then re-open it, and it would be OK for a good while - - I'm loosing my mind with this - Does anyone have any ideas on what may be causing this?

    - "default" Desktop and Ctrl+Alt+Del Hello, I'm currently programming an application which is started replacing the userinit.exe. The code does the following. When the user logs on the application is creating a new desktop "newDesktop", then the original userinit is created at "newDesktop". So the shell uses "newDesktop" as its desktop, too. The same is with the other applications, that are started when the user logs on. After starting the original userinit the program creates another desktop "formDesktop" where the forms of my Desktop are displayed, while the system configuration of the logged on user is loaded in the background. In this form the user has to solve some tasks and when this is done correct the "formDesktop" closes and the "newDesktop" is set as visible Desktop and the program exits else the user will be logged off. For sure you ask why "newDesktop" for the shell process? The answer is that when the user logs on the visible desktop is "default". If I don't use "newDesktop" the user can manipulate the desktop before the form is displayed and this cannot be allowed. If the application sets the "default" desktop visible before exit the hotkeys and trayicons and so on are still registered to the "newDesktop" and not the "default" desktop, so "newDesktop" stays the user's desktop for the session. What is the problem I have? Well, the ctrl+alt+del event opens the taskmanager in the "default" desktop, thus it's invisible to the user, although the process exist. Making the long story short, here is the question: Is there a way to make the taskbar appear in the "newDesktop" when ctrl+alt+del is pressed? I hope I could make myself clear. kind regards, Alexander Tag: Help to trap Datagridview cell keypress events... Tag: 110772

    - DataGridView: last column can be made smaller but not bigger Hi, I have a DataGridView control where the user can resize the columns. The control is embedded inside a Panel. When clicking on and dragging the column seperator to the right of the rightmost column, I can make the column smaller when I move it to the left. If I try to move it to the right however, my cursor is halted against the edge of the control. So the column can't be made bigger. This can be reproduced in the sample at http://msdn2.microsoft.com/en-us/library/1x64c23x.aspx by clicking Customer->View Orders in the main form and doing it on the table that appears. In that sample, it is possible to make the last column bigger again by making the whole window bigger, until its length is more than the total length of the columns, creating an open space between the columns and the edge of the window. Then the right seperator of the rightmost column can be dragged freely, up until the edge of the window. However, this trick isn't practical in my own control, since the control is too small and the total column length too long. Is there some standard way to make it behave like the list view in Explorer, where you can resize past the border of the window?

    - How to avoid flicker when adding controls to a panel? Hi, I've got a flickering-problem when I try to add controls to a panel (with flow layout) at runtime. My code executes the following steps: public void BuildView() { ... // suspend layout to not perform layout each time an item is added mFlowLayoutPanel.SuspendLayout(); // remove all elements from the panel: mFlowLayoutPanel.Controls.Clear(); // in a loop I add new items to the panel: foreach (... in ...) { Panel panel = new Panel(); // set size of the panel: panel.Size = MaxSize; // MaxSize is a constant value // then the color of the panel is set panel.BackColor = Color.CornflowerBlue; // after all the panel is added the the panel with the flow layout mFlowLayoutPanel.Controls.Add(panel); } mFlowLayoutPanel.ResumeLayout(true); } Every time the method BuildView() is called, the panels are flickering. What went wrong? I thought that SuspendLayout() and ResumeLayout() will avoid that? How can I avoid flickering every time my panels are added to the flow layout panel?

    - Datagridview and the Enter Key Hi all, I have a datagrid that doesnt allow the user to edit. When the user clicks a row, the whole row gets selected. I'd like it so that when the user has a row selected and presses enter, a new form is opened and passed data from the row. At the moment, when I press enter, I can get the window to open, but the selected row moves down one. Is there any way I can surpress this behavior when pressing enter?

    - Child form focus problem Hi all, An application I am woking on consist of a main form. On the main form there are several possible ways for the user to open a non-modal child forms to display even more information. The problem I am encountering is about loss of focus. Let's say here, that initialization of the child form takes about =BD second, from the point where the window is first shown to the point where all controls have been rendered and set with data. Now, on the main form there is a datagridview which is updated on intervals. The problem occurs the user clicks a button to open a child form. The child form is created. But before initialization of the child form has finished, the DataGridView on the main form is updated. Seemingly because of this, the main form gets focus and is moved to the front, and the child form is moved to the back. The user can manually put focus on the child form again and continue working, but tuhis is a behaviour that is very anoying to the end users. Have any of you encountered something like this before? The non-modal strategy is by design. The users want to be able to go back to the main form, without closing the child form. Therefore, I'm searching primarily for any help on the focus problem, and will only use a modal child form strategy if no resolution to the problem can be found.

    - Windows Form App and VPN I have some clients who have users who reside outside of the company's network. The company is going to allow remote access through a VPN on the server for access to the SQL Server database. I want to have my forms app which will run on the client machine to automatically open the VPN when the program starts and close it when the program ends. That way, the clients doesn't have to set anything up and they don't have to worry about how the data is accessed. Is it possible to this from a windows form app and if so what operating systems would the client have to be running in order to do this? Bill Tag: Help to trap Datagridview cell keypress events...

    - OnPaint automatically call e.Graphics.Clear()? Hello. I have a question about OnPaint override. For example, if i have the following code in my inherited form class, private Brush _brush = Brushes.Black; private RectangleF _rect = new RectangleF(0,0,100,100); private int counter =0; protected override void OnPaint(PaintEventArgs e){ if (counter==0){ counter++; e.Graphics.Clear(Color.White); e.Graphics.DrawString("Test", this.Font, _brush, _rect); } } I expect the OnPaint method will do nothing after the first call. That means, the string "Test" should stay on screen if the form is not resized/moved/covered by other windows. However, in reality, the OnPaint do the e.Graphics.Clear() automatically. I'd like to know if that is possible for me to stop that behavior. In my application, my form contains many individual text strings. The strings are updated periodically individually. I would like to render the updated strings only, not rendering the whole thing for every string update. Thank you very much for your help!

    - Filtering key strokes Hi, having a card reader attached to the PS/2 keyboard interface, I would like to filter the keyboard input, so that the input from the card reader does not reach the GUI controls. I tried setting KeyPreview=true on the form and catched all input with the KeyDown event. In order to detect, if the input comes from the card reader, I need to check a sequence of at least 10 keys. So I collect the keys in KeyDown and if it's a card reader sequence, I trigger a special action for it. If it's normal user input, I need to "forward" the collected key strokes to the form. The second part is the complicated one. Having a sequence of key strokes in an array of type System.Windows.Forms.Keys, how do I resend these to the application? Sendkeys only accepts a string and seems to not support all values of the System.Windows.Forms.Keys enum. Is there maybe a way to resend keystrokes using the integer values captured from the KeyValue member of the KeyEventArgs? bye, Marc T. Tag: Help to trap Datagridview cell keypress events...

    - What are my options in this Windows App? I am creating a Windows Forms app that will use SQL Server as the database. The app will be used in the following ways. 1. It will be used in the Clients office where the app will sit on the clients desktop pc and connect to the database on the server. 2. It needs to be used by those outside of the office network. ex. a remote office that is not a part of the network where the database is residing. 3. I might have users on the road that with wi-fi access need to connect to the office database. I don't want to create a browser based app using ASP.Net. I don't want to use Citrix. Here's what I think are my options. Am I missing any? which would you recommend? 1. Create a windows forms app that sits on the client and a web service that sits on the server that connects to the database. The user does something on the client and a call is made for data to the webservice which returns data to the client. 2. The app creates an opens up a port upon startup and accesses data directly and then closes the port upon exiting the app??????????????????? Any other suggestions or recommendations?

I have tried using threading and updating the databound object (by marshalling to the UI thread) by using a separate thread however there are still delays when 32000 rows / items are added. It stops other windows from responding for a brief second. I also have an animated gif on the form and that stops responding. Is is possible to have the datagrid run completely within a separate thread, or have two UI threads run in the form so that the form and animated gif is not affected when the datagrid updates? Any help with this would be appreciated Tag: Help to trap Datagridview cell keypress events... Tag: 110665

    - Validating bound text box I have a windows form (.net 2.0). On this form I have a BindingSource. I set the DataSource to a dataset that is created in code then "built" using the ReadXMLSchema method. I have have bound a textbox to one of the fields in that BindingSource that is of type int. If I type anything but an int, I cannot do anything. I cannot close the form, I cannot set focus on another control. No exception is thown. The DataError event on the BindingSource doesn't fire. The Validating event on the TextBox fires and in fact I have had to check the value so that I can raise a message if the item is not a number. But I would rather catch whatever it is that is stopping me from leaving that control and displaying an error at that point. -- Russel Loski, MCSD.Net Tag: Help to trap Datagridview cell keypress events...

    - clickOnce (more instances of installation) Hi, I have created a basic application, which is deployed as clickOnce and has some dll and one config file. Application 1 = main .exe file + dlls + one specific .config file Application 2 = main .exe file + dlls + another specific .config file ... What do I need to set to install them as completely independent ? I tried to change everything in ClickOnce Deployment Manifest file, but one application still updates the second one... In ClickOnce Application Manifest file, it seems that there is nothing specific changeable, but maybe I'm wrong. (I need also have two shortcuts in Start/Programs, but as I said, one installation always replaces the another... ) Thank you very much for any answer or idea Ondrej Dobecka ondradocasny@community.nospam ondrej.dobecka@tietoenator.com Tag: Help to trap Datagridview cell keypress events...

I did this recently by adding event handlers for key presses directly within
the classes that I'd derived for my columns. In your case, if you are lucky,
it may be that all you have to do is derived from the data grid view text
cell and then pass your events directly down in to the base class.
