The problem to make the marker size of Legend bigger with MS chart control Seraph_summer2-Jan-09 4:34 Seraph_summer 2-Jan-09 4:34  Generally, the marker size of the legend should be changed automatically with changing the marker size of the corresponding series. but I found that when the marker size of the series is increased to larger than some value, the maker in the legend does not change at all! (it is changed only when the marker size is increased from very small value to some value, then it is not changed anymore!) is this the bug of Chart Control? I found the maximum marker size in the legend is too small for me, I try to make it bigger, but I can not. anyone can help me to clarify it? comparisons between Zedgraph and MS chart control Seraph_summer2-Jan-09 4:07 Seraph_summer 2-Jan-09 4:07  I compare the speed of plotting between Zedgraph and MS chart control, I found MS chart control is much slower than Zedgraph. Anyone knows the reason? Or just because MS chart control contains more functions which may need more time for initialization or because MS chart use differet implementation technique from the one Zedgraph?

I just plot the same line chart with Zedgraph and MS chart control (i.e., the same x and y list values), then the time taken by MS chart control is much longer than Zedgrah.

Just use the control that works best for you. Christian Graus Driven to the arms of OSX by Vista. Re: comparisons between Zedgraph and MS chart control Dave Kreskowiak2-Jan-09 6:13 Dave Kreskowiak 2-Jan-09 6:13  Your testing, or results, is very incomplete. Besides, the MSChart control is older than dirt itself, wasn't designed with the .NET Framework in mind (interop overhead, and pre-dates even the idea of the .NET Framework). Then there's ZedGraph, which was designed entirely under .NET. Is it really such a surprise??

Note 1 : i don't want to do this by caspol.exe, i want to do this by code or setting properties(within my app). Note 2 : i found this url[^] for grant permisson to assemblies (Using the Trust Assemblies Location Property), but it is for VSTO and i want to do this for Visual Studio 2005. can anybody help me ? Thanks Re: How to set my app full trust (CAS) ? [modified] #realJSOP2-Jan-09 3:26 #realJSOP 2-Jan-09 3:26  I'm not sure a) you can do that programatically, or that b) it's a good idea. Security is put into place for a reason, and any application that attempts to circumvent it should be untrusted.

Re: How to set my app full trust (CAS) ? Mark Churchill3-Jan-09 15:55 Mark Churchill 3-Jan-09 15:55  Yes it is possible to do it programatically. Obviously your application will need to be full trust to do it. Think it though! What would be the point of having this security if an application can just grant themselves the permissions they don't have without any checks?

I am using Visual Studio 2005 and C# to develop a Windows application. My database is a MS Access 2003 database. On my Form I have a DataGridView that is bound to a table in the database. There are also a few DataGridViewComboBoxColumns that are bound to different lookup tables in the database. I specify the BindingSources for all of these using the designer. When I run the app the DataGridView is populated as expected. The DataGridViewComboBoxes also work fine and I can change the values. The database is also updated correctly. So everything seemed fine. Then I added a Button control to the form by dragging a Button control from the Toolbox onto the Form. Before I added any further code I ran the app again to check something. This time I encountered a problem. After I clicked the Close button in the Controlbox (Top right on the form) the DataGridView gets cleared of data row by row and when all the rows have been cleared the following message appears: "Index 0 does not have a value.". I just cannot see the relationship between just adding a Button to the form and this error message. I am stumped and any advice will be appreciated. Regards. Kobus Re: Problem when closing Form containing DataGridView #realJSOP2-Jan-09 2:51 #realJSOP 2-Jan-09 2:51  It seems pretty obvious that you're trying to delete one more row than the grid has. Try using the debugger - I know, that might seem too much like being a programmer, but after the first few times, you'll find the debugger to be pretty damn useful.

What baffles me is that I have not made any changes. I have not added new records, or modified records. or deleted any rows. I run the app and immediately closes it and the error comes up.

For saving web pages, work with "WebClient" class. It has got methods to download a file or data from a webpage. Then use regular expressions to see what are the other resources (images,styles etc) used and send separate request for these to download. There should be an article on this here in CP.

My application has a DataGridView, which contains a DataGridViewComboBoxCell. Is there any way to make the combo box drop down its list on the first mouse click? Currently, the first mouse click activates the cell, the second one creates the hosted combo box, and the third click finally drops down the combo box list. I'd like the combo box drop down immediately on one click instead of 3. Thanks and best regards Dominik Too many passwords to remember? Try KeePass Password Safe! Re: One-Click DataGridViewComboBoxCell kbalias2-Jan-09 1:58 kbalias 2-Jan-09 1:58  Hi I am not sure if you can set it for individual cells. If you set the EditMode of the DataGridView itself to EditOnEnter then the comboboxes drop down at the first click. Unless another DataGridViewComboBoxCell was in open position. Then the first click will first close the open one and the second click will open the selected DataGridViewComboBoxCell. All the other cells in the DataGridViewRow will also now be editable as soon as they get focus. Regards.

Kobus debugging BHO Maverickcool2-Jan-09 1:12 Maverickcool 2-Jan-09 1:12  hi i'm having troubles debugging an BHO with IE7 and VS 2008 i'm using the BHO from http://www.codeproject.com/KB/cs/Attach_BHO_with_C_.aspx[^] the application is working fine for me I searched to how to debug BHO. this is what I found: "Set your IE home page set to about:blank . That way you can start up the browser as fast as possible and go where you need to. So, start up the first IE window. Then, from VS.NET use the Attach to Process item in the Debug menu to attach to iexplore.exe. Set breakpoints in your BHO. To break within the constructor, just open a second IE window." I did that but it didnt work for me it's just ignoring my breakpoints do you know otherway to debug? or maybe I'm missing something? thanks
