Thank you. That was the answer I needed. I have implemented the hash table into the application and it does the trick. The application I'm working with is well established and this particular feature, which happens to be a search for a serial number based on a bar code value, is a specific request by one customer. I can't redo the application simply to fit one customer need, and so I wanted something that works with the existing application architecture, which you have provided.
Thanks.

I did do a google search and looked at a few books but am stuck.
I have a form that I want to reset the text boxes on:
1) reset the text boxes within the group box
2) reset the whole form

Excellent - now what have you done so far? How far have you got with your code - or were you wanting us to write the code for you?

Thanks for the reply smart guy (AKA ass). Want a chance to redeem yourself?
What I am asking is a newbie question and I have no idea how to go about reseting a whole group of textboxes. Questions I have asked myself:
Is it possible?
Is it a built in function of the MS C# IDE like "groupbox1.child.text = ""?
looking for some help and not smart ass comments.

if you mean to reset the controls to its a default value for a property i.e Text you may follow this step
1. create list to buffer a property value for each controls in your form
2. get property value back to controls according its index
sample
private ArrayList initialValues = new ArrayList();
private void StoreInitialValue()
{
foreach (Control ctl in YourForm.Controls)
{
initialValues.Add(ctl.property);
}
private void ResetToInitialValue()
{
for (int i=0; i< YourForm.Controls.Count; i++)
{
YourForm.Controls[i].Property = (typeof(your.stored.property.type))initialValues[i];
}
}
}
hope it helps

Hi,
Does anyone know a free (or not too expensive) C# lib for fingerprint reading and comparation?
Thanks,
Dirso.

You might want to take a look at Windows Image Acquisition Library (WIA). I've only used it for document scans but it may have what you need for fingerprints.
If you're working with specific hardware, then you may want to check and see if the vendor has a C# library for their products.

I was looking to add in some simple word processing ability into my application. I need spell check and a few other simple things Microsoft Word does.
Does anyone know of a control / article that could offer any assistance here?
The less word automation needed, the better.

In .NET 3.+ WPF, spell-checking is built into either the textbox, richtextbox, or both. As for other capabilities their are a few articles on this site that can assist you. Do a quick search.

check out visual studio office tools:
www.microsoft.com/downloads/details.aspx?FamilyId=5E86CAB3-6FD6-4955-B979-E1676DB6B3CB&displaylang=en
You got a version for VS2005 (.Net 2.0)
and a version for VS2008 (.Net 3.5)
Using these tools you can write add-ins to word and/or use word's controls.
besides that, if you like you can automate/control word application itself using office interop (just google it). meanning, you can automate real instance of word to do things for you...

Hi all,
I need to call a business logic class via web servicing without using reflection. I pass the class name and method as string parameters in the web service. But it doesn't work the conversion from string to an object.
If I pass the object class then it works but I don't want to do that as the webservice must run independently
The code I use is,
[WebMethod]
public object ExecuteMethod(string ClassName, string MethodName, params object[] arguments)
{
object obj = null;
Type type = Type.GetType(ClassName);
try
{
obj = type.InvokeMember(MethodName, BindingFlags.Default |
BindingFlags.InvokeMethod, null, null, arguments);
}
catch
{
throw;
}
return obj;
}
Thanks in advance

ClassName need to be a fully qualified type name.
BTW: what you are doing is reflection
|

|

Could you provide me with the code without using reflection
Thanks

Hey, guys.
In searching for a solution to my problem below (http://www.codeproject.com/script/Forums/View.aspx?fid=1649&msg=2645163[^]) about stopping the MS dialog boxes in the WebBrowser control, I've discovered that the IWebBrowser2 interface has a property called Silent that seems to fit the bill. WebBrowser doesn't seem to implement IWebBrowser2 out of the box and embarrassingly, my COM background is in C++ rather than C# so I find myself fumbling a bit.
I'm hoping it's only minor rocket science to derive a new WebBrowser control & implement this interface so that I can get to the Silent property. All I'm using the browser control for is to navigate to a site & then save off an image capture of it to a jpeg. Everything is working fine, but I'm getting hammered by MS messages boxes complaining of scripting errors, unknown publishers, etc. (and I've tried all the browser control properties and IE options to no avail). I'm hoping Silent works as advertised.
Apologies for such a newbie question, but a little guidance in this area from the more experienced hands would be most appreciated. What's the quickest path to getting IWebBrowser2 implemented on the WebBrowser control?
Thanks!

Hey, man.
Thanks for the link, I appreciate it. I actually downloaded and looked at that around 4 AM this morning. He'd done a really nice job on his control, but for both the problem I'm trying to solve and as a simple tutorial on implementing IWebBrowser2, it's major overkill for my needs. He's implementing the interface, but it's buried in with a ton of other stuff and I just don't have the time to dig for it.
I was hoping to find a quicker, simpler, more to the point article entitled, "How to implement IWebBrowser2 when you're just too plain stupid to use COM in C#, in three easy steps." Or something of that sort. One can dream.
I do normally enjoy going through a good book or article, especially of this quality, but it's crunch time on this project (i.e. code till you fall asleep at the keyboard, wake up, code some more) and I'm currently just trying to put out the fire at my feet as quickly as possible. You know how it goes...

Dude, don't use WebBrowser to scrape a screen. Use networking stuff to get the HTML directly!

Actually, I'm doing a fair amount of that in a different portion of the system, but that's a different critter.
What I'm talking about here is saving a screenshot of the web site's home page, which means something needs to read the HTML, handle all 90 gazillion variations of language versions and malformed tags, and then ultimately render that HTML as a graphical image. That's pretty much the short definition of a browser, which is why I'm useing the WebBrowser control to save off the jpeg of the home page screen shot.
Man, if there's a better way to get that jpeg that doesn't require me to deal with browsers, scripting errors, malware, IE popups telling you that they've done something about said malware, etc. then I'm absolutely all for it. Is there something easy and obvious that I'm missing here?

I am porting a VB6 winsock.ocx based library to a .Net Sockets implementation, and I am not the most savvy sockets programmer. The architecture of the communication system was designed long before I got here; so changing the overall design is not an option. Moreover, this system has a low frequency of tcp traffic, so the Socket.Connected will almost always be out-of-date.
The fundamental issue is the connected property of the socket. It does not seem to be funcitonal; however, I have found others that have had similar issues http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.connected.aspx[^]
When I stepping-through the code in the debugger, unplug the network at the right moment, and view the sock object with the quick watcher, it shows me the value of sock.Connected has changed to false as expected. However, while running the code below, in debug mode but not stepping-through, the behavior of sock.Connected is different (when I unplug the wire, it does not update to false).
Thoughts?
private bool isConnected(){
bool rVal = false;
try
{
bool blcking = sock.Blocking;
try
{
byte[] junk = new byte[2];
sock.Blocking = false;
sock.Send(junk, 1, 0, SocketFlags.None);
rVal = sock.Connected;
}
finally
{
sock.Blocking = blcking;
}
}
catch (SocketException e)
{
rVal = e.SocketErrorCode == SocketError.WouldBlock;
}
return rVal;
}

My thought is, I hope you are hung up on the concept of interrogating the socket for it's state because that's what you saw in the VG6 *gulp* uh, mess. I hope you appreciate how difficult it is for me to even type VV6, see I just can't do it.
Using exception handling you can can just execute your code and catch exceptions indicating the socket is not connected. You should search around the internet, Sockets.com has been around for ever. Look for examples like the one in the documentation for Socket.Send[^]

I don´t know if you got the anser to your question, if not try to download some chat applications here in codeproject.
I started to built one but i didn´t finished it yet, and i didn´t find the code to acomplish all the things i have in my mind.
I´am not an advanced programmer but, i see in your post some similar code to the one i typed (and read before).
Good Luck
