  • this.Width=30; NOT WORKING!

    - by j-t-s
    Hi All, I've been doing this for years. But now it's just not working. private void Form1_Deactivate(object sender, EventArgs e) { this.Size = new Size(30, 29); txt.Visible = false; lbl.Visible = false; } The form just does not change Width. But, as above, the 3 controls DO become invisible. Any suggestions?

  • ASP.NET MVC model state as text

    - by David Moorhouse
    Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?

  • Usage of initialize() vs. setup() in Mootools

    - by RyOnLife
    Mootools classes have an initialize() method that's called when a new object is instantiated. It seems that setup() is a commonly used method as well. Most classes I've observed call this.setup() from initialize() and nowhere else, which has left me wondering: What's the purpose of setup()? Why not just put the setup() code in initialize()? When does it make sense to use a setup() method?

  • Code formatting when using pointers

    - by HD-VRSCA
    Is there any reason why the asterisk is next to the object type in this code? I'm a little confused by the way I see this used. Some times it looks like this: NSString* stringBefore; and sometimes like this: NSString *stringBefore; Is there a difference? Or a right or wrong way to do this? Thanks

  • Contact page MVC workflow

    - by alex
    All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?

  • How to integrate camera image into physics engine?

    - by Pedro
    I recently came across this and would like to implement something similar. The basic approach is clear: I have to threshold the image and check if a virtual object collides with the remaining foreground. Instead of implementing the physics myself, I'd like use an engine like Box2D. But how do I integrate the thresholded image into the physics engine so it is possible to interact with virtual objects?

Any ideas what to change here?

  • empty base class optimization

    - by FredOverflow
    Two quotes from the C++ standard, §1.8: An object is a region of storage. Base class subobjects may have zero size. I don't think a region of storage can be of size zero. That would mean that some base class subobjects aren't actually objects. Opinions?

  • Stopping a service and waiting in VBScript

    How can I stop a service and wait for it to finish stopping in vbscript? I've got this so far: For Each objService in colServiceList If objService.DisplayName = "<my display name>" Then objService.StopService() End If Next Googling turned up a suggestion of using objService.WaitForStatus( ServiceControllerStatus.Stopped ), but running that gives me an error of "Object required: 'ServiceControllerStatus'".

  • Any way to anticipate session timeout ?

    - by Tom
    Hi, Is there a way to "catch" the session timeout event, so as to retrieve data from HttpSession before its invalidated ? We're implementing the Filter Interface, and in the doFilter method, the user we stored in the session object at login is null when session times out. Thanks in advance.

  • ASP C# How to handle large files from database?

    - by Martijn
    In my web application I am working with files. Some files are very large. I use Response.Write() to write the file to the browser. This goes well for the smaller files, but for large files this can take a while and the bandfwith is fully used. My question is, is it possible to split large documents and send it piece by piece to the browser? I hold the document as a property of an object.

  • Hibernate reverse engineering

    - by EugeneP
    I have a structure where the main table is USER, other tables include CATEGORY (contains user_id). What I got after the standard reverse engineering procedure was: the class User contained a collection of categories, the class Category didn't contain the foreign key (user_id) but it did contain the User object. Why did it not contain the foreign key as a class property? And how do I join these two tables in HQL without that glue? HQL - please explain this part.

    - by ra170
    I came across people passing data objects as: declaration: DataObject * data = 0; calling it as: SomeMethod( data ); definition of Somethod: void SomeMethod(SomeObject * & object) My obvious question is, when and why do you have to do this (& *)? Is it passing the pointer as reference?
