Are you a student... I hope.

I am a little new to building WIndows Services and was curious if i could just create a single project named company.windowservice and deploy create multiple services in here? If so when installing the service would all services created within this single dll have to be installed as well? Any ideas? Thanks...

I'm trying to communicate with a piece of test equipment on our LAN, and I thought TcpClient would be a quick and easy to do this... I'm using VS2005, and here's what's happening...
I establish a connection to the server (the test equipment), create a stream, and write data to the server. I get the response back, and I'm happy. Then I try to send another message without closing the connection or the stream, and the write occurs, but the read freezes.
If I close the stream and connection to the server, and then build them up again, everything works fine. It just seams like a very inefficient way to do it!
I must have a basic misunderstanding of either TcpClient or the stream GetStream returns... 
Any idea what going on?

Can't be sure because you provided no information about the protocol you are working with.

Hey all,
I have a C# program that opens a word document for editing.
I need to have it open, then locate a particular line and column in the word doc, then print a text value in the spot located.
Does anyone know how I should go about this?
Thank you!
Dave

sorry if I was vague. I just need to know if there is a snippet of code out there that I could use to find a coordinate in a word document.
|
|
|
|
|
Can you give us more information as to what information you have that define what will be selected?

Well the location is (line,column) so that is very confusing.
dspyank wrote: then print a text value in the spot located
What does that mean? Insert text at that location? If so you need to go look at the Word Object Model documentation.

Mike,

locate a point ( Line 4 Column 65 )
Then have my program write to that point.
I will check out the documentation.
Sorry I was so confusing, but thanks for your help!

hello
i'm using the visible poperty to hide the panel but it doesn't hide the controls on the panel.
is there any other way other than through the visible property.

They hide that information in the documentation[^] 
but the property should work for all the child controls of the panel. If it doesn't then you must not have the other controls as children of the panel.

plz guide me on making child control on a panel.
i simply add controls by draging them from the toolbar onto the panel
|
|
|
|

Control visibility is hierarchical, if you hide a control (by setting Visible=false)
all its children are also hidden; other controls, that are not children of it,
will not be affected even if their coordinates are such that they overlap and seem
to "belong" to the panel.
So it all boils down to: make sure the controls you want to hide by hiding the panel,
have been added to Panel.Controls, and not directly to Form.Controls

do we add controls to Panel by Panel.Controls property or is there any other method.
do tell cause i'm pretty new to C#.Net
|
|
|
|
|
to add controls to a panel, you program it like this:
Label lbl=new Label();
myPanel.Controls.Add(lbl);
if you are using Visual Studio Designer, just have a look at the code
it generates for you, and you will find such statements in a method
called "InitializeComponent" it generated for you
you are not supposed to edit this method, since that could confuse (maybe crash?) the
designer afterwards.
Adding a new control to a panel with Designer is automatic: if you click inside the panel
to indicate where and how large the new control is going to be, it is automatically added
to the panel, not to the form.
But copying with Designer, I don't know how to specify where it belongs. Just dragging
is NOT sufficient. You can get it right by trial and error, keep looking at the Property
pane, for the Location property, it is always relative to the parent, so if, while dragging
your new control suddenly has much smaller x,y values then it has been adopted by the
panel !

Hi,
An application written in C#-VS2005 needs to use a class exported in a VC6Dll.
I have googled around a bit about Data Marshalling using P/Invoke. But all I could find is information on how to use the exported functions from a dll OR a struct from a dll.
I could not find any info on how to use the (exported,unmanaged) class of the dll in my C# App.
Any help or link woud be helpful.
Thanks and Regards,
Arti Gujare

Hi Led,
I did have a look at this site. For each class to be used from the dll a skeleton(StructLayout) of that class has to be defined in the project using that dll. However, the dll I am talking about is huge and consists of too many classes. I have approximately 16 exported classes which I would be using. 1) Is there a better way to do this?
These classes again have member variable as objects of other classes not exposed from the dll.
2) Could you tell me how to write the StructLayout for a class having private members as objects of other classes.
Regards,
Arti Gujare

I noticed a huge difference in time in zipping a folder (which contains x amount of files) and selecting the files inside and zipping the x amount of files inside the folder). Why is that?
|
|
|
|
|
1 - Is this the appropriate place to ask.
2 - Can you explain what you mean, you're not being very clear.
I have no idea what I just said. But my intentions were sincere.

I have a c# .net program...which generates pdf files. After all of them are generated I zip them.
Now, I had about 330 files a total of 112 MB. My program was taking an awful lot of time to zip these files. I decided to zip manually to see how long it takes. These 330 files are in a folder. If i right click on this folder and click send to compressed folder it is a lot faster than selecting all the files at once (i mean going inside the folder and selecting all the 300 files all together) and clicking send to compressed folder.
|

When your program zipped all those files, did it instruct the ZIP library to do that as a
single operation, or was it a for loop adding one file at a time ? For all ZIP stuff
I have seen, each ZIP operation tends to create an entirely new ZIP file in a temp directory...
