Iam currently in the middle of writing a screen grabbing app in c#. One of the requirements for the application is that the form or window of my application doesnt appear in the grabed images. Under XP this was easy as I just set the form to not appear in the task manager in the form properties in visual studio and when it was minimised you couldnt see it at all.
The same nearly applies to vista, I cant see the window when minimised and it doesnt appear on the taskbar. However when it is minimised I seem to get a floating tab of the window in the main desktop.
I dont know if this can be disabled with a vista control panel setting or there is some other way of doing it with code but I cant seem to find it either way. Can anyone possibley help with this.
Much appreciated Mike

Try to write a subject line that says something about the thread.

Yes, of course.

If you are going to be running a single instance of the application, any database will be able to handle that amount of data, even an Access database.
If you are building something that are going to be used from several instances of the program, or is going to be incorporated into an intranet/extranet, or if you see any of this as a likely development in the future, you should use a more stable database solution, like MS SQL Server.
You don't have to forsee any future needs, though. MS SQL Express is fully compatible with a full grande MS SQL server, so it would be fairly easy to upgrade if needed. Any type of database can be imported to another, but there are some differences in connection, data types and sql queries.

But i guess these kind of applications are better if done using ASP.Net as it could be worked via webpage(internet) or intranet(if want to use it locally with in campus).
Please correct me if am wrong.
If i am right then i should build this application using ASP.NET, C#.NET, ADO.NET, SQL server 2005
Thanks

It depends on what the application has to be able to do, really.
Most applications that work against a database doesn't really benefit much from being windows applications, as they are working against a central database anyway.
Web applications have some benefits over windows applications, though. All that you need to use it is a browser, you don't need any .NET framework or specific datbase drivers installed. You actually don't need the computer to run Windows at all.
Unless you have some special requirements in the application that needs it to be a windows application, you can very well make it a web application.

Hi,
I have written a script where user can upload a file into a pre-defined destination file. But I want to add couple features to this
1) I want to validate so that only preferred users can access this application.
2) Everytime a user uploads a file, a log table needs to be updated with the user name(may be windows login name), upload date& time, File name etc.
Can some one help me with the scripting part for this pls.
Thank You

hi,
one way is to iterate through all the items in the list and add them.
you could try the following:
object[] obj= new object[listBox1.Items.Count];<br />
listBox1.Items.CopyTo(obj,0);<br />
int sum = 0;<br />
foreach( object o in obj)<br />
{<br />
int tmp = Int32.Parse((string)o);<br />
sum += tmp;<br />
}<br />
textBox1.Text = sum.ToString();
and one more thing please don't post the same message in multiple forums.
hope this helps
regards

Iterate over the items of the listbox and sum them
|
|
|
|

Well the concept of listbox is that it holds multiple values just like an array but the listbox control treats every data as string .lets assum that we are having a listbox name lbt1 holding seven values each value on each index.
We have to apply a loop first untill the total number of items in lbt1.e.g
// declar/initiate variables
int val=0;
int addval=0;
int total=0;
for(int i=0;i<this.lbt1.items.count;i++)
{
val=int.parse(this.lbt1.items[i].tostring());
addval=addval+val;
}
this.txt1.text=addval.tostring();

i want to use directx to capture screen then save to file,because i know only a little about managed directx,so the first i Want to create a device link to the desktop,then copy the data from that device,but after i instanced a device,i can't use it,i do not know why, my code like this:
IntPtr hwnd = WinApi.GetDesktopWindow(); //i use api to get hwnd
IntPtr hdc = WinApi.GetDC(hwnd);
Device device = new Device(hdc); //instance here
//then i didn't know how to get the data i use this code
Texture t = Device.GetTexture(0); //can't work here
//or i use this
Surface s = device.GetRenderTarget(0); //also can't work
i really don't know how to do can get the data from the screen then save to file,i hope someone can help me to deal with this question,or you can give me a method to capture the screen,but do not use the gdi+ or graphics.CopyFromScreen method, i only want to use directx to do that. thanks.

You don't want to use DirectX for that, it's just not needed, and doesn't really help. You're on the right track, you just need to copy from the hdc to a bitmap. The desktop is not drawn using DirectX

thanks for your answer, but if i want to save the screen continually like a vedio, i will save 24 bitmaps per second, this will use a lot of CPU and memory, so i'm finding a way to save the screen more quick and less use up. could you tell me how to do that,thanks very much.

Hi,
In my business logic directory I have a Property class. The namespace for this class is:
namespace MyWebsite.BusinessLogicLayer
{
public class Property
{
}
}
In my website, the I have a backend (admin) control panel where property is added, and the namespace is:
namespace MyWebsite.Web.ControlPanel.Property
{
public partial class InsertProperty : System.Web.UI.Page
{
}
private void InsertNewProperty()
{
// Here I try to insert a new property
}
}
In the InsertNewProperty() I get all the values from the input controls. When I try to create a new instance of the Property class it doesn not find it, instead it gives me an option to chooose only from the Property namespace. My reference to the Property class is like this in the .aspx page:
using MyWebsite.BusinessLogicLayer;
So I do not know what it does this. Can someone please advise me correctly?
Regards
ma se

hi,
in such conditions, use full name:
eg:
MyWebsite.BusinessLogicLayer.Property p = new MyWebsite.BusinessLogicLayer.Property()
hope this helps.
regards

you can alias one of these property objects with a using statement. It's something like using MyNamespace.MyObject = MyNewName, but I'm not sure of the precise syntax.

as Christian mentioned, you could use
using MyNewAliasProperty = MyWebsite.BusinessLogicLayer.Property;
then in code
MyNewAliasProperty p = new MyNewAliasProperty ();
regards

|

|

You can also use an alias for the namespace:
using Bll = MyWebsite.BusinessLogicLayer;
When you want to specify a class in the namespace, use the alias:
Bll.Property prop = new Bll.Propery();

If you can change name of either class or namespace (Properties perhaps?) by all means do it. If it is late, it is late, and use aliases as suggested above.
