• Windows Forms Problem : Anchored ComboBox get selected automatically when its container resize.

  Hello, I have a problem with the comboBox and I can't find a proper solution. I have many combo box that are docked fill in a TableLayoutPanel. When I resize the table layout, all combo box that DropDownStyle is DropDown get selected (all text are selected). This is very inconvenient since we have to go click in each combo box to unselect their text, and the UI is horrible. The solution I found is that always keep all combo box in DropDownList style, and change the style to DropDown when it get Focus (override OnEnter). This works find except the case the the combo box get focus by a click on the dropdown button, the dropdown appears and disappears right away, cause a flashing of the window. My solution for this is override WndProc t ...Show All

• Visual Studio Tools for Office Word2007 Add-In: Can I customize the Word Options dialog ?

  Hello, I am developping an Add-In for Word 2007 with the VSTO3 CTP (this add-in will be released using Cypress) I would like to know if it is possible to customize the Word Options dialog box. Typically, I would like to add a category to the left pane and provide UI elements to control the options of my add-in. For the time being, I use a custom dialog bow that I show using a button in a custom ribbon, but I am looking for a more elegant solution that would be more tightly integrated to the new Word 2007 UI. Thanks in advance for any help. There's never been any interface exposed in the Office object models for this. And Office 2007 concept is much more restrictive about what customizations are allowed.

  Hello All, Does anyone know how to set the list index of a DataGridViewComboBoxColumn. I have no problem populating and retieving the ValueMember. I just can't figure out how to set the DataGridViewComboBoxColumn to a specific item within its list programmatically. Sound simple enough. Your help is appreciated. Kind Regards, JimS ;^) Hello, I noticed that you stated that "It is important to note that if you use a DataReader to populate the Dataset the DataGridViewComboBoxColumn will display the ValueMember rather than the DisplayMember", which is the problem I am having.

• Software Development for Windows Vista turning off MIC

  Hi, Can any one help me out to turn out the MIC feature in Vista.It has some option in system's control panel as i hear.But where exactly can we do it. Thanks & Rgds Soujanya There sort of isn't a way to do it. There IS a way to shut off UAC in Control Panel, definitely. But MIC -- which I'm told is now called "Windows Integrity Control" or "Windows Integrity Mechanism" -- doesn't have an on/off switch. There's really only one big use of it in Vista anyway -- IE Protected Mode. That can be shut off if you need to. ...Show All

• .NET Development Network Logon Failed-Home network

  I am testing a simple remoting solution and it works fine with all of the components on the same computer. However, when I test over 2 machines on my home network I am able to connect to the remote machine (and instantiate the remote object) with no problems, but when I attempt to call one of the remote object's methods I get a System.Security.Authentication.AuthenticationException exception: "A remote side security requirement was not fulfilled during authentication. Try increasing the ProtectionLevel and/or ImpersonationLevel." with an inner exception of: "The network logon failed" I am guessing that this is similar to connecting to SQL Server over a home network where you can't use Windows Authentication across ma ...Show All
