I need my app to be the default action for opening a particular file type. How do I control this? Also, how can my app access the file being opened?
Thanks.
In what circumstances would updating a UI control from a non-UI thread could cause the processes' handles to continually increase, when using a delegate and .InvokeRequired?
For example:
public delegate void DelegateUIUpdate();
private void UIUpdate()
{
if (someControl.InvokeRequired)
{
someControl.Invoke(new DelegateUIUpdate(UIUpdate));
return;
}
// do something with someControl
}
When this is called in a loop or on timer intervals, the handles for the program consistently increase.
I am using visual inheritance and was wondering if there is a way to change the properties of inherited controls at design time, preferably in the form designer. If not, then in the designer code.
I have my control declared as Public in the base class. I can access it in the child form code, but not in the form designer. Is this just not possible?
Does anyone know a tool that automatically compares the structure of a database and gives a report of what was changed? If it can be integrated into a CruiseControl, even better.
By structure I also mean functions and stored procedures. Which is probably not clear at first sight ;-)
The idea was to integrate that into a cruise control server
I have a WPF ListBox control and I'm setting it's "ItemsSource" to a collection of item objects. How can I bind the "IsSelected" property of the ListBoxItem to a "Selected" property of a corresponding item object without having an instance of the object to set as a binding.Source?
I doubt it is good practice but I was wondering if it is possible to register a control that is in the global namespace.
something like
<pages>
<controls>
<add namespace="global" assembly="MyControlAssembly" tagPrefix="mca" />
</controls>
</pages>
Thanks!
Dear experts,
I download the Android code and "make sdk" to build out my own SDK, but the emulator from this SDK does not work well -- it only shows the black window with the "ANDROID" string, but I can't see any desktop picture or any applications. what's wrong here? anyone could please provide me a hint? Thanks a lot.
I use the command:
$./emulator @jiawelin -debug all
and the last output message is:
emulator: android_hw_control_init: hw-control qemud handler initialized
I hear a lot of Emacs users have their init file under git version control and sync the git repository over Dropbox, when they run Emacs on multiple systems.
Why would you use git in this situation exactly?
Usually checking which system you're on and which things to load and set depending on that can happen in one and the same init file for all systems, right?
So, isn't it simply enough to put your init file in a Dropbox directory and load that one directly from Emacs then?
I'm having an issue with the treeview control from the silverlight 4 toolkit. I can't get it to view to display my data correctly, the toplevel items are shown but the childnodes are nowhere to be seen.
More info:
I have a wcf service that delivers a list of Categories with nested subcategories to my viewmodel (I made sure to explicitly include my subcategory data). My viewmodel has an observable list property (wich is named Categories) with this data from my WCF service.

Hi All,
Was just wondering how I would go about letting the user resize a TextBox control at runtime by dragging its corners in WPF. Less importantly, is the same technique used for the resizing of all controls?
Thank you :)
Hi,
I have a query related to Touch events on the UI controls.
I have 4 controls on the screen ( UITextField, UISlider, UISwitch, UIButton ). If the user touches any of the control on the screen, I want to fire touchesBegan and touchesEnded events on those controls in which I would implement some code.
Please let me know how to fire these events.
Thanks in advance,
Sreelatha.
I need to implement a list control using MFC with the number of lines being fixed. It should Use FIFO with the number of lines being a fixed number. Is there an inbuilt option to this? Or a programmable method.
I would like to create a function in C# that takes a specific webpage and coverts it to a JPG image from within ASP.NET. I don't want to do this via a third party or thumbnail service as I need the full image. I assume I would need to somehow leverage the webbrowser control from within ASP.NET but I just can't see where to get started. Does anyone have examples?
With asp.NET control dropdownlist, there is a property AutoPostBack, if it is set "True", the whole page will be posted back.

Recently i try to learn something about the unix. when i try to edit something using the vi command, it is very difficult for me since i have to switch the edit mode and control mode time by time. It is very inconvenient. Is it that i miss something or it is originally like that? Is there anyway to improve that? Thank you :)
I have a problem on adding a webpart to sharepoint page.
I have a blank page in the sharepoint, and I have a custom control uploaded to the site, on adding the webpart the the sharepoint page I get the following error:
"Attempted to use an object that has ceased to exist. (Exception from HRESULT: 0x80030102 (STG_E_REVERTED))"
I get that error even if the sharepoint page is totally blank and so is the web part.
I'm creating a web front end to control a small robot. Ajax calls will be made on a keydown, to start the robot, and keyup to stop it.
My problem is that when a key is held down the keyup, keydown, and keypress events seem to cycle continually. Does anybody know of a way to only have keydown fire when the key is first pressed and keyup to fire when it has been released?
Is it possible to require the user be authenticated (logged in) when downloading ZIP files from my site? Note that I don't have direct control of IIS7. (I'm on a shared hosting account.)
I can't simply alter the access for a particular directory because many directories are involved and most contain other files that can be accessed freely.
I've Googled this a bit and found similar questions. But I've been unable to find this exact question.
The Faking User Roles document in SDN appears to give exactly what I need. I have a few "roles" that I have access to through stored procedure calls I don't control, read-only, via a CRM I don't have direct access to.
Unfortunately, I can't find the method AddRole, or even the class UserItem, by its present name. Does this functionality exist in Sitecore 6.2? If so, where is it?
When I view my app's memory in the xcode memory tool, i see that something called QuartzCore is reported as leaking many times. Each leak ranges from 16-80 bytes.
My code is not referencing this. it's all from withing UIApplicationMain(). So I'm not sure how to control this. Any ideas?
Thank you.
how do I load a page in an iframe and set focus to a form element once the page loads? I don't have control over the page I am calling into the iframe, but I know the name of the form is 'form' and the text field I want to focus on is 'go'.
