Yes.
Given that RAM is cheaper than disk access, you're better off storing the data in memory and writing any changes to the XML (assuming you want to persist the list across application runs) file.

Hi,
I am getting following error while opening windows form in solution
"Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information..."
I Rebuilt the solution and all references are also fine. But still i am getting the error and could not able to open the form in design view.
I saw an article saying hotfix is available for this problem at MS site (http://support.microsoft.com/kb/912019/en-us), but the page is not available.
Any ideas are welcome
Thanks

I was wondering if anybody knew how this dll works?
http://www.deskperience.com/textcapture/index.html
Basically I need to get text information from another application's data grid. I could use api calls to get text from a textbox or list or just about anything but the data grid. Any ideas? Thanks.
P.s. I really want to avoid OCR if at all possible.

You could do this, but unfortunately I can't remember which APIs you'd need to call, also it'd be fairly specific to your application.
|

|

It doesn't matter how specific it has to be per application, I just need to be pointed in the right direction. Does anybody know the API calls?
|
|
|
|
|
The basic strategy would be to use the Win32 API to get a handle to the required control and then look for functions which can extract text from that handle. I'm not sure which APIs you need to call but I think that if you look through the MSDN documentation the names of the functions are fairly self-explanatory.
|
|
|
|
|
I am getting as far as getting the handle to the control but there aren't any api calls for getting datagrid information. Only listboxes/text boxes, etc... This is where I am stuck! I searched msdn and didn't find a thing.
|
|
|
|
|
Is there a handle for the individual cells of the datagrid?
Are you trying to access a .NET datagrid or is it a "classic" Win32 control?
|
|
|
|
|
.net, and I can't seem to get individual handle to a cell... the handle is for the datagrid itself.
|
|
|
|
|
Are you always going to be dealing with a .NET control or do you also have to interop with "classic" components? If it's just a .NET control then I seem to remember that there's a way which you can deal with getting a reference to the .NET object.
Of course if you're dealing with both then you could just put something like: if(classicComponent) { do Win32 stuff } else { do .NET stuff }
|
|
|
|
|
May not always be .net... If I could get an example of either though, I'm sure I could figure out the other once I have sort of idea of a direction to go in. Do individual cells of data grids have handles?

I have no idea and I'm afraid at the moment I don't have too much time to investigate, I might have some time later in the evening but unlikely.

Hello,
I've read the following article:
http://support.microsoft.com/kb/319401[^]
It actually worked very nicely with my project but when I grouped listView items (using Group property) it stopped working completely.
Can you please tell me how can I fix that?
Your help would be greatly appreciated.

Hello,
I am trying to set background image to listview, but when I load image it doesn't get adjusted to listview size (stretch - auto size adj.)
I using following code to load image
mListViewUI.BackgroundImage = Image.FromFile(@"c:\jpeg\image1.jpg");
Any help is appreciated.
Thanks in advance.
|

|
|
|
Isn't there a BackgroundStyle (or something similarly named) property which handles this, it's an enumeration with Stretch, None, Fixed, etc as values.
|
|
|
|
|
Bitmap bmp = new Bitmap(mListViewUI.BackgroundImage, mListViewUI.Width, mListViewUI.Height);
mListViewUI.BackgroundImage = bmp;

Hi,
I am developing a MDI application. In this application on click of some menu items I have to display some forms(say MenuForm1, MenuForm2, MenuForm3) with some data. But at the same time I want one form(say BackGroundForm) which is a child form of my MDI application should be active in the background of the form which gets displayed on click of some menu items.
If I declare those forms(MenuForm1, MenuForm2, MenuForm3) as child & if I pop them up using ‘show’ then for 1st time they are visible in my application but next time if I click that menu item then they are not visible. Same problem I’m facing if I don’t make them as child of my MDI & pop them up using ‘ShowDialog’. I am hiding forms(MenuForm1, MenuForm2, MenuForm3) on click of a button which i placed on same forms(MenuForm1, MenuForm2, MenuForm3).
I want that ‘BackGroundForm’ in my application because I want to put some button controls on one form & that form should be active all the time until the application is running. So I had put some buttons in this BackGroundForm & I cant put buttons on MDI parent form .
How I can solve this problem in my MDI application…?
Thanks in advance,
Vinay

I'm new to using the Visual C# 2005 Express - is the console window
supposed to just flash up and disappear when displaying output from
a console program? The book examples I'm using seem to assume so.
I've found a code snippet: System.Console.ReadLine();
which does the job, but is it usually necessary to include this line
or something similiar to keep the output window from disappearing please?

Well, usually you'd execute a console app in a command prompt window, so the app would execute and return to the command prompt.
If you double click it in explorer, it will open a command prompt window, execute, and when your program is done, it closes the window.
ReadLine is waiting for user input, so the app hasn't ended yet, which keeps the window from closing.
In other words, it's a hack to keep the window open.

No this is supposed to run under the MS Visual C# IDE. I have two "step-by-step" type books
and both expect the programs to run using the IDE environement; neither seem to consider this
problem...
