How can data be collected that is sent to a native application? Is there a way if I wrote a launcher program to watch all the data sent to the app I launched?
Or if I watched a particular table handle?
Thanks,

There is no reliable way to do this. An application can get data in so many different ways it's silly. There's simply no way to catch them all...

What's a "table handle"?

Hmm, nothing reliable? Anything useful though?
A table handle is a value assigned by windows to various application windows.

There is no standard for something that cna't be done in only one way. How many different database engines are there? How many ways to access them? How many ways to get information in through an IP port? Memory mapped files? RPC calls? Named Pipes? ... Starting to get the idea now?
You have to target VERY specifically the method the application uses to get this information. And in most cases, you'll find that what you want to do will take an extraordinary effort to accomplish this.
And it's not a "table handle", it's a window handle. Information is not passed through that handle. It's used to indentify windows to which messages are sent. And just about all methods for getting information into an application do NOT use a window handle to do it.

I'd like to write an app where c# can set or retrieve values that are on a editable pdf; anyone know of a product allows crafting of fill / edit pdf 's to be manipulated like this?

Distiller?
As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

 Hi folks
I am receiving an error when I attempt to add a typed dataset to a windows form.
The error msg says:
"Could not add an instance of
ClientsWinClient.localhost_DeckAndLaundry_ClientsWebService.Clients1 to the
designer.
To resolve this problem, build the project, fix any errors, and add the
instance to the designer again."
I have done all that, to no avail. I have even deleted the web reference for the form and then recreated the web reference, but it hasn't made any difference.
This is running on a PC with windows XP PRO SP2 and is using the .net framework version 1.1.
If somebody could assist, I would be most appreciative.
Kind regards
Ross Petersen

i have a c# application and i want to distribute it to many people.
i believe not all of them have the FRAMEWORK
i can not give them all the 32 MB. ( right ?)
is there any thing like : "take from framework JUST WHAT IS NECCESSARY " ???
so the file will be smaller ?
and if not , what can i do ?
|
|
|
|
|
Tell them they are better off when their system is up to date and install the framework.
Other possibility would be NOT to use .Net but C++, VB6 or something similar instead.
|
|
|
|
|
At this moment if someone on Windows doesn't have .NET framework then that is mainly theirs problem...

Why not? Direct them to the correct download page at the Mictosoft homepage, where they can download the framework if needed.

If you application is the simple app (e.g. Desktop application) and there's no need to dynamically load/create types or expose types defined in your app to external clients (plug-in, unmanaged apps) - you can try one of these "IL to executable" compilers.
All these products are commercial (at least I haven't heard of any open source/freeware products) - google on "Xenocode, Salamander, IL Compiler" and try it out.

HELLO ALL ,
I HAVE A CRYSTAL REPORT ON SQL SERVER 2000.
THE REPORT EXPORTS INTO PDF FILE
THE REPORT HAS MINIMUM 500000 ROWS JOINING WITH OTHER MASTER TABLES
THE QUERY IN REPORT TAKES ABOUT 15 MINS TO RETURN RESULT.
BUT WHEN I TRY TO EXECUTE THE REPORT IT TAKES HOURS AND HOURS BUT DOES NOT RETURN
THE PC CONFIG IS
P3 1GHZ 1 GB RAM ECC , 72GB SCSI HDD
SQL SERVER 2000
VISUAL STUDIO 2003 WITH CRYSTAL REPORT 9
THANK YOU
Vola !!!!

Hi
This might be caused by the way CrystalReports builds it SQL query statements. It builds VERY complex SQL statements by joining all the tables you linked through the wizard. The best way to optimize the performance is using (optimized) SQL-Expressions for data selection with your own sub-selects instead of linking the tables through CrystalReports.
The phenomenon that executing the report takes much longer then working in designer could be caused by the fact, that CrystalReports caches the data once loaded.
Maybe this helps you a little bit
Best regards,
Don Teflon

Thank You,
The Problem seems that
When the report executes it tries to cash the entire report into memory and then export
But when i chopped the data into batches of 100000 records
Each exutions takes 22 mins to complete.
so there mabye a bottleneck of report against hardware performance
Anyway Thanks a lot 
Best regards,<br />

Apparently there are no event associated with a change of the form's WindowState property.
How do I know when my windows has been miniaturized?
|
|
|
|
|
If I remember right with every state change the SizeChanged event gets thrown. You would then just have to compare it with the previous state.

Yep, I found out just a little while ago 
Thanks anyway!

I installed some software on a client's PC today and had some weird issues with layout and window resizing. He was running Windows 2000 (not sure what service packs right now), and I had to install the .NET Framework (2.0) for him today.
For example, I had some Label controls (with image backgrounds set to a fixed size) positioned in the top right corner of the form (inside a Panel actually) and anchored to the top and right. On his PC though, the Labels were floating about ~30 pixels lower than they should. The rest of the controls seemed to be layed out like normal.
Also, the Form had a minimum size set, but no maximum size. It starts at the minimum size, and resizing the window larger works fine for me on my machines. On his machine, though, the form *started* smaller than the minimum size and he couldn't resize it up to or past the minimum size. He could resize it UP a little bit, but even then it was less than the Form's minimum size (I could tell because of the layout of hte controls and the background image on the Form). The other form used in the application is set at a fixed size, and I set it so you cannot resize it, but oddly enough that form started *larger* than that set size.
Has anyone else seen this behavior? I have installed this same software on other machines in the same company that were also running Windows 2000, and it worked fine, so I'm not sure if it has to do with the machine running Win2K or not. All my test and development machines are Windows XP. Maybe it has to do with his settings under Display Properties -> Appearance in Windows? I'm just hoping someone has seen this before and knows how to fix it or exactly what is causing this behavior.
Any help is greatly appreciated, thanks!
Andy

I suspect there is a mess between your client's DPI setting and the AutoScale property of your control.
Just as a quick check show the Window's display property => settings => Advanced
If the DPI setting is not 96 that could explain it...

Hola, I am trying to use C# to make a HTTP POST request. This request should carry file data, and have some parameters in it as well.
This is quite easy with HTTPRequest, but the problem is, I need progress information as well, and the only apparent way to do this is to use the WebClient classes (UploadFile or UploadData). I've been trying both the whole day, without much success.
My code looks something like this:
WebClient client = new WebClient();
Uri uri = new Uri(url);
// Placing the parameters in a name-value collection
NameValueCollection param = new NameValueCollection();
foreach(string[] nameValuePair in parameters)
param.Add(nameValuePair[0], nameValuePair[1]);
// Addin headers.
client.Headers.Add("User-Agent", "MyApp");
// Adding the parameters
client.QueryString = param;
client.UploadFileAsync(uri, "POST", fileName);
Basically, judging from the server response, it appears that the server can see that a file is coming in, but cannot read any of the parameters that I send along in the request. To make matters worse, WebClient is doing something dodgy while using the HTTP protocol: none of the requests turn up on my HTTP sniffer! So I can't tell what is going out of my computer.
Help!!!
