• Dave9999 Column header painting - text margins

  Hi, By default, there seem to be 6 pixels between the column divider and the first letter of a column header. I'm trying to reproduce the exact look & feel of another application, which has 3 pixels in its grid headers. So I need 3 pixels, (left and right), not 6. Is there an easy way of setting this I looked at the FAQ, which had a section on "Row Pre Paint and Post Paint". I'm not familiar with GDI painting, is there any simple code I can use to get this effect I don't really have time to try myself at the moment... Thanks! Hi,goPlayer Try something like this: DataGridViewCellStyle style = new DataGridViewCellStyle ( this .dataGridView1.ColumnHeadersDefaultCellStyle); Padding padding = new Padding (); padd ...Show All

• hazz Programicaly creating a ShortCut

  In my Windows Forms application I have created a self-exracting archive (Program Installer) for my main application. How would I go about creating shortcut icon that points to my applications executable file I looked in the System::IO::File class but couldn't find anything and don't know where else I would have to look. Thanks much! (I am making a transition from C++ to C#, so you will have to excuse my obliviousness to things like this.) :) C# doesn't use header files. A rough equivalent is Add Reference in the Solution Explorer... I am using VC# Express Studio so I don't believe it has the "Setup Project" in the Express SDK. And the second link you provided is broken. Another quick question... ...Show All

• Tony_NTFY dataGridView; selecting cells

  When the user presses the enter key, I want the next cell (in the same row) to be selected. How can I achieve this in a dataGridViewControl   I didn't find any property about the 'enter' key behavior. So, I think this can be solved overriding the onkeydown method on your datagridview, or handling the datagridview's keydown event on your form. To select the next cell you just do this: DataGridView1.CurrentCell = DataGridView1.Item(DataGridView1.CurrentCell.ColumnIndex + 1, DataGridView1.CurrentRow.Index) I hope I could help you. I had a similiar issue which I solved using the code below. I could not get the desired effect by simply overriding OnKeyPress, c ...Show All

• Christoph_S Windows installer problem

  Hello! I install my aplication as administrator and I choose "Everyone" during installation. I install it in c:\Program Files\myApp. When I try to run this aplication as ordinary user then it appeared error message that access to the path c:\Program Files\myApp\somefile is denied. It is caused because I try modify config file which is created automatically by exe file (and it is placed in Program Files where ordinary user  doesn't  have permission to modify  any files). How can I solve this problem Thanks for help. Sebastian If users (or the application running in user context) needs to write to this file you shouldn't put it in the Program Files Folder in the first place. If you reall ...Show All

• Matti-Koopa Uninstall Problem?

  Dear all, I created a msi setup in vb.net, after i have installed the application. I tried to uninstall the application. However, after the uninstallation, some of the files cannot be removed by the uninstallation. Is there any ways to remove all the files Thanks Regards George yeah, i agree, i noticed it too for most installers. thanks stefan for clearing it up. can you recommend a more detailed documentation for orca then Orca is just a simple table editor and IMHO very simple to use. What you will need however is a detailed understanding of the tables that make up the msi database. This is documented in the MSI SDK: http://msdn.microsoft.com/library/en-us/msi/setup/windows_i ...Show All

• Dinesh Kokate Designer wont save property on overridden datagridviewcolumn

  I've overridden a datagridviewtextboxcolumn and the cell it is using. I have created a property for my custom column that will show up in the designer but when I change its value through the designer it will revert back to the default property value. I can set the property manually through code and it will work. I have tried this by both by 1) storing the private variable itself in the overridden DataGridViewTextBoxCell, creating a public accessor in it, and also creatung a public accessor in the overridden DataGridViewColumn to access the Cell's public accessor, and 2) creating the private variable and public accessor only in the overridden DataGridViewColumn, and accessing it's value from the GetValue method of the cell by calling th ...Show All

• Jared2000 Help in implementation of a magnifying glass

  I have an image viewer application which I want to apply a magnifying glass effect on certain area of the image. The problem I've run into is that when I slowly dragged the magnifying glass across (when left mouse down) the magnifying glass window didn't move smoothly. I believe it has something to do with drawing the graphics of the original image on the background. May someone please help me solve this issue Thanks. This "this.Update()" method call in picPanel_MouseMove() is probably the source of your problem. Invalidate(true) should be good enough. Actually, you shouldn't need anything there; Windows should detect that the moved magnifier window has revealed a portion of picPanel that ough ...Show All

• Suthy67 textbox.SelectAll() does not seem to work.

  I want a textbox to highlight any text when it gets focus in such a way that I can subsequently paste a few characters from the clipboard over this entire text with the right click mouse. I placed a command this.textbox1.selectAll () in textbox.GotFocus method but it does not highlight anything. What am I missing Thanks. You can override Method OnGotFocus. I was also in thinking about the problem, and had to dig in my old projects that do such things, it was my Masked Edit Box Control. There i see that i had used this method. Project was in VS 2003 but will also work in VS 2005. protected override void OnGotFocus( EventArgs e) { base .OnGotFocus(e); this .SelectionStart = 0; this .SelectionLength = this .Text ...Show All

• Steve1999 How to get history of 10 recent web page?

  Hi! How can I get the history of the recent webpages (For example the 10 most recent webpages are in a menu strip and a new item is added everytime a new page is navigated to) Matt depends how your application is handling the history. usually to store the history you would write to say, an Xml file (serialize the collection of webpages you have visited), then deserialize this list once you are loading up your application again. you would have a section in your menu strip with the 10 recent pages visited, so whenever you add another one, if there are 10, take away the oldest one (the first one in the list) and replace it with the new website you are visiting. ...Show All
