I'm trying to use different functions like SendInput and SendKeys to send input for controlling a DOS program running in a Command Prompt window (very old DOS program - no source code). Both of the above functions work on a standard Command Prompt, but it doesn't work on the DOS program once I run it. It also seems that many of keyboard macro programs don't work on these types of DOS programs either.
Does anyone know of how to send the key input in the way that many DOS programs are reading input from the keyboard?
I solved this once a very long time ago using libs in Windows XP (still running this OS) but lost the code and my source of information  .

It may be almost impossible. Some DOS programs talked directly to the hardware to get input and you can't do that in Windows unless you write a kernel mode driver. Even then it may still be infeasible. Get real and junk the DOS program - this is 2007!!!!

Actually it is totally possible with a project right here on CodeProject!!! http://www.codeproject.com/cpp/sendkeys_cpp_Article.asp
It took me this long to eventually find my functioning code, which led me back to the article. Now I just have to check that a C# version exists and if not I will convert the project myself.
I am real, and I can't junk the DOS program because I work in the real world where you can't just re-write software on a whim to meet the latest craze, especially where it would be dangerous to do so (people's limbs at risk).

I am glad you have found a solution that works in your particular case.
I am real too, I make my living writing programs for the real world. DOS programs started to die ten years ago and no critical applications should rely on such programs any longer - hardware and software support is non-existent; it is a matter of chance whether they can be made to run now and there are absolutely no guarantees for the future (i.e. next week). Development of an alternative to the DOS app should have started at least five years ago.
Whatever may be said against Windows there has never been a more universal, stable and consistent operating system on which to develop software for all sorts of applications. To speak of it as a "whim" and "the latest craze" is dangerously short-sighted, especially if people's limbs are at risk!

how should i use the parametercollection class , i mean i have the following information like
Stored procedure Parameter Name
Stored procedure Parameter direction (input/output)
stored procedure Parameter value
stored procedure Parameter Type (decimal , string)
Now how should i use the parametercollection class , in order to insert this information i the add function

Yahoo Messenger Id = soniagupta1

i tried the following code
class abc
{
ParameterCollection p;
public ParameterCollection ab
{
get
{
return p;
}
}
}
public class waste
{
public waste()
{
abc a;
a = new abc();
a.ab.Add("ParameterName", TypeCode.Decimal, "ParameterValue");
a.ab[0].Direction = ParameterDirection.Output;
a.ab[0].Size = 100;
}
}
can i improve the code?

I generally use a set of helper methods. Roughly, they do the following:public static DbParameter Parameter<T>(string parameterName, DbType parameterType, T value, int size)
{
DbParameter param = Parameter(parameterName, parameterType, value, ParameterDirection.Input);
param.Size = size;
return param;
}
public static DbParameter Parameter<T>(string parameterName, DbType parameterType, T value)
{
return Parameter(parameterName, parameterType, value, ParameterDirection.Input);
}
public static DbParameter Parameter<T>(string parameterName, DbType parameterType, T value, ParameterDirection direction, int size)
{
DbParameter param = Parameter(parameterName, parameterType, value, direction);
param.Size = size;
return param;
}
public static DbParameter Parameter<T>(string parameterName, DbType parameterType, T value, ParameterDirection direction)
{
DbParameter param = new DbParameter();
param.Direction = direction;
param.Name = parameterName;
param.DbType = parameterType;
param.Value = value;
return param;
}Then, all you need to do is cmd.Parameters.Add(Parameter("@ID", DbType.Int, 100));

Pete, that seems a lot of work for what I usually do:
int value1 = 10;
cmd.Parameters.Add(new SqlParameter("@param1", value1));
Or am I missing something?

Sort of. The full version that I have takes care of a lot more than this, and is standardised so that more complex types of parameter can easily be created.
There's been a lot of work put into the library to ensure that it copes with a wide variety of cases - including things like automatically putting the right parameter modifier (e.g. @) onto a parameter name, based on the database type. It's sort of a cut down version of the Enterprise Library, and it means that we can target multiple databases with the same codebase, just by changing an entry in the config file.

Aah, thanks. Would you mind clearing something up for me please? The excerpt generates a compiler error for trying the call the protected constructor for DbParamter. Were you just generalising for the example? If so, I'm curious to know how you implement concrete helpers.

This was a very generalised example, mainly to demonstrate the fact that you can use a DbParameter. Our routines actually accept the DbCommand and use the CreateParameter method on this. One hint as to why we don't use the Enterprise Library - our routines can work with delegates (anonymous methods), attributes and default values. They've grown over the years, as our experience/needs with our clients has grown.
One day, I might write an article on them and detail how they've grown. It's an interesting way to document how infrastructure evolves with client demands.

what is DbParameter in this context?

If you just target SQL Server, just replace this with SqlParameter. DbParameter is the base class that SqlParameter derives from, and (as noted in the other posts in this thread), requires slightly different behaviour.

Hi Pete....
can u tell me something about <T> in the following context.
<code>public static SqlParameter Parameter<T>(string parameterName, DbType parameterType, T value, ParameterDirection direction)</code>

It's a generic parameter. It basically means that you can pass the value in without having to box it to an object then unbox it. Without this, you would have to declare object value.

Hi,
I have a MdiParent Form, that contains MdiChild forms. That MdiParent also contains some controls on it (panels). Default MdiChild Form behavior is that it is displayed behind all control's on MdiParent. So if there is a panel on MdiParent and I drag a MdiChild so it interferes with panel, panel is in front of it and I can't see the MdiChild part behind the panel.
Is there any simple way how to change this default behavior, so that MdiChildren are in front of all MdiParent - controls ?

Hello,
I think there is only the possibility of "BringToFront()"
All the best,

No. This cannot be changed. All MDIChild forms are rendered on a control docked as Full in the MDIParent form. This control is called the MDIClient. Any other controls you place on the MDIParent form will always hover over the top of the MDIClient control.
You will have to either get the reference to the MDIClient control (it's in the MDIParent form's Controls collection, just like any other control), and turn off it's Dock property, and resize it to give you room to put your other controls on the MDIParent, OR you put all of you're other controls in their own seperate window.

Hi,
I want to that then click a back and forword internet explorer button then appear message in asp.net C#
|
|
|
|
|
|

What sort of message ? Do you want to forbid it, or just pop up some message ? I'm not sure that javascript can tell that you've pushed those buttons, if it can, then you can write javascrpt to do that.

what the best biometric fingerprint scanner or reader that is easy to manipulate using c# or vb.net?
im about to purchase one to be used in one of my client. we will be using it for employee daily time record.
can anyone point me to the right direction of what type/model/brand to use? i have not used this type of equipment before.
thanks in advance

Hi!!
Maybe I can help you. In a recent project I have test two models from different manufacturers:
-DigitalPersona...
-FingKey Hamster
We decided to decline DigitalPersona because is too slow starting when operating system starts and to capture fingerprint. Hamster doesn't not. IS very fast and has a payment sdk with samples to c# with a low cost. And now you have a second version on Hamster(Hamster II). I recommend it.
Look here -> http://www.nitgen.com/New_site/eng/product/pc_hamster.asp
I hope this help you.
