Thanks a lot for your help PivotTable and SpreadSheet Components [modified] hamidreza_buddy27-Jul-06 6:54 hamidreza_buddy 27-Jul-06 6:54  Hi What is the activex control name for PivotTable and SpreadSheet?

If so, I want to overload graphics.drawline() which signature in CF is drawline(pen, int x1, int y1, int x2, int y2). I want to change it to drawline (pen, point A, point B). Any help? Donkaiser Re: overload native function J4amieC27-Jul-06 6:02 J4amieC 27-Jul-06 6:02  er, that overload already exists! (in class System.Drawing.Graphics) public void DrawLine ( System.Drawing.Pen pen , System.Drawing.Point pt1 , System.Drawing.Point pt2 ) --- How to get answers to your questions[^] Re: overload native function [modified] donkaiser27-Jul-06 6:06 donkaiser 27-Jul-06 6:06  Sorry! it's for CF. this overload is missing. But my point is to see if it's possible to overload IDE methods. Re: overload native function Ennis Ray Lynch, Jr.27-Jul-06 6:23 Ennis Ray Lynch, Jr. 27-Jul-06 6:23  Whats an IDE method? Either 2.0 or 3.0 ( idk which ) has a method for adding additional methods to a class. If you do a web search for new features of the two it can direct you. If those are not available the pattern is a wrapper class. A man said to the universe: "Sir I exist!"

Donkaiser Re: overload native function Ennis Ray Lynch, Jr.27-Jul-06 8:17 Ennis Ray Lynch, Jr. 27-Jul-06 8:17  Its extension methods and I think it is in 3 only. Looks like you need a wrapper class.

Donkaiser Edit a column in a datagrid without using the edit column [modified] Mons211027-Jul-06 4:49 Mons2110 27-Jul-06 4:49  Hi, I was hoping if someone could help me with this problem. I want to edit datagrid entries without using a linkbutton column for edit and update. maybe we could do this using javascript. But I dont know how? On an 'edit settings' button click outside the datagrid, the cells in the datagrid should change into dropdownlists and textboxes with earlier values maintained. Thanks!

You only need to have an 'Edit' trigger if you want to open up a seperate view of the record. Detecting when one side of a Socket Connection Closes Kurt _B27-Jul-06 4:22 Kurt _B 27-Jul-06 4:22  I am using the Socket class to communicate between two applications and if I close my server app closing the socket connections my client app is unable to detect that it is closed. Even doing a send from the client app does not throw an exception. Does anyone know how to detect if a socket has been closed from the other side? Thanks Kurt Re: Detecting when one side of a Socket Connection Closes Not Active27-Jul-06 5:37 Not Active 27-Jul-06 5:37  What does the Connected property read as when you do this? Is there a timeout issue, i.e. you haven't waited long enough for the timeout to kick in and say the connection has been closed? only two letters away from being an asset Re: Detecting when one side of a Socket Connection Closes Kurt _B27-Jul-06 6:20 Kurt _B 27-Jul-06 6:20  Connected property is true. Even tried waiting a few minutes. Using asynchronous methods which do not use a timeout I believe. key down in windows forms (C# 2.0) [modified] C-Scharbe27-Jul-06 3:56 C-Scharbe 27-Jul-06 3:56  i want to catch any key down event in my windows form. but it doesn't run, because there is maybe an other control in the formular that is focused, so the key down event reacts only on that inner control. how can i catch any keydown event without referencing each control in the formular to the keydown event? another method i know is to create a menustrip and give them shortcuts (but i think it's not the perfect solution) _______________________ where is the "any" key? -- modified at 7:11 Wednesday 9th August, 2006 Re: key down in windows forms (C# 2.0) Ilia Blank27-Jul-06 4:06 Ilia Blank 27-Jul-06 4:06  Do you want catch just any key down or only key down when one of the child controls of your form (or the form itself) is focused? Re: key down in windows forms (C# 2.0) C-Scharbe27-Jul-06 5:14 C-Scharbe 27-Jul-06 5:14  any key down not specially to a control in the form Re: key down in windows forms (C# 2.0) Ilia Blank27-Jul-06 5:47 Ilia Blank 27-Jul-06 5:47  You have to install windows hook procedure to intercept all keyboard events.

Re: key down in windows forms (C# 2.0) Ilia Blank27-Jul-06 6:32 Ilia Blank 27-Jul-06 6:32  It will work only if the the form captured the input. As far as I unerstand the goal is to catch all keyborad key downs regardless to the current window. Re: key down in windows forms (C# 2.0) C-Scharbe8-Aug-06 21:31 C-Scharbe 8-Aug-06 21:31  i want to catch all keyboard key downs which were sendet if any control in the current window is focused (without catching each key down of each control in the window.) Re: key down in windows forms (C# 2.0) C-Scharbe8-Aug-06 21:39 C-Scharbe 8-Aug-06 21:39  i setted the keydownpreview true of the form and create a keydownpreview_event of the form, but the event does not trigger.
