Create the button with an onclick event, and set it's ID based on a property of the data source, so you can work it out from there.

Hi Christian:
Thanks for the reply.
When I add the button I select the Select button from the Button column in the datagrid properties. The only place I can see to set its ID is in the Command name text box in the datagrid properties. I also tried using a Delete button and Edit, Update, Cancel buttons.

If you're using webforms, don't use the designer, it's crap. You want to set the ID using ID=<%DataBinder.Eval("columnName")%> within the aspx code.

I need to create a login(registration) page using Windows Forms for redirecting different users to access data from an Access database.Could you please give me any hint about it?
|
|
|
|
|
So you want to use passwords from the Access database, from the Windows account, or of your own creation ? You're writing a Windows Forms app that uses Access for the data layer ?

Actually I want for the users to put in the form their own registration data which will be written in an Access database.Thank you

So the passwords are stored in Access ? Then all you need is to check access to see if hte password and username match, right ? Which bit are you stuck on ?

Greetings,
I am working on a C# desktop application.
There is a piece of code when the user clicks on the tracking number, it should bring the browser to the UPS web site and pass the tracking number to the web site to get currently delivery information.
I was wondering who knows the right syntax to pass the variable string to the web site.
So far, I am just passing the literal variable (track_no).
the code is as follow:
string track_no;
ControlName[iCnt,7].Tag = "http://wwwapps.ups.com/tracking/tracking.cgi?type1=1&inquiry1=track_no"
If you can, please reply to my email hsu@arbonne.com.
Thanks a Million
Handy Su

Greetings,
Never mind, I figure it out.
The answer is as follow, if some stuck like me in the future.
ControlName[iCnt,7].Tag = "http://wwwapps.ups.com/tracking/tracking.cgi?type1=1&inquiry1=" + track_no.ToString();

Dear All,
Does anyone know how can I call a function from an Intel Library?
Please help...
Best Regards,
E.A.

What language is the library written in, C? If C, you can use P/Invoke[^] to call the native library.
If it's written as a C++ class instance function, then you may need to wrap the dll in a managed C++ function that instanciates the class and calls the member function.
If the DLL uses COM (which I doubt, coming from Intel), you can add a reference to the dll itself inside Visual Studio (or manually use the .NET aximp tool), and a runtime callable wrapper will be generated automatically for you.
Tech, life, family, faith: Give me a visit.

Thanks Judah,
It's in C/C++...
Actually I have a ".dll" file in the bin folder,a ".lib" of type C/C++ inline file & an "exports library file" in the lib folder...
Shall I call the .dll or the .lib?
What's the use of the "exports library file"?
Sorry if my questions sound naive but I have never dealt with dlls before...
Best Regards,
E.A.

Hi,
I'm using Visual Studio 2003 .NET and the application has this title bar with a heading and two buttons - hide/show and close - this title bar is circled in the image provided (image link). My question is what kind of a control is it, or maybe a combination of controls and how do I create something like that to insert into my form.
Top red oval in the image is the title bar I'm asking about

Thank you in advance.

They are called docking windows, your in luck because I have tried out loads of different ones today, see the article Dock Manager for a free implementation, if your after designer support and more I've found either SandDock or Actipro UI studio are the best.
The larger circle in your picture is called a propertygrid this is part of the framework, right click your toolbox and choose add/remove items as it is not enabled by default.

How would i be able to use tags on nodes in a treeview to store and retrieve information.
|
|
|
|
|
If you have a bunch of Infos you want to store in a node you could make a helper class containing everything you need and store it in the node:
private void SetInfo(MyInfosClass info, TreeNode node) {
node.Tag = info;
}
private MyInfosClass GetInfo(TreeNode node) {
return node.Tag as MyInfosClass;
}
A in my opinion better idea would be to inherit from TreeNode and add some extra properties.
public class MyTreeNode : TreeNode {
private string _info1;
private int _info2;
public string Info1 {
get { return _info1; }
set { _info1 = value; }
}
public int Info2 {
get { return _info2; }
set { _info2 = value; }
}
}
With this solution you naturally would have to instantiate and use the MyTreeNode class instead of TreeNode.

Hi all,
I am considering using the default xml serializer in C#.
My concerns for using the default xml serializer or implement the serializer code myself are as follow,
1. The class has arrayList inside which need to be serialized.
2. The class have base class which also need to be serialized.
3. I need to control the depth of the serialization for the objects referenced by the class
So what should I adopt ? Use the default serializer or write my own code ?
Thanks
|

|

1. No problem - the ArrayList is also serializable
2. No problem as long as all used classed are serializable (either by atrtibute or ISerializable interface)
3. Probably a problem but this depends. With the default behaviour this isn't possible. You will either have to implement ISerializable to hae a better control on what is being serialized or have an ISerializationSurrogate to stop certain classes from being serialized. If later is valid in your case depends on your data structure.
(Bonus)
4. Keep in mind that .Net serialization is rather slow. If you are serializing a rather big amount of stuff you'll be better of doing it yourself. This is especially true if you have lots of small objects.

Thanks so much.
Then I think I need to do it for myself coz speed is my first concern.
May I ask you also whether any pattern for this kind of manually serialization so that I won't miss out any attributes in the class to be serialized manually or it can reduce errors as my class already changes ?
|
|
|
|
|
I don't think I have any real good advice for you. The only way to reduce errors would be to write an Unit-Tests which first serializes one instance of your class, then deseriealizes it and checks the equality of the result with some kind of recursive technique using reflection to catch all fields.

This may be a wierd question but has anyone ever heard of interaction between Assembly and C#. Some instance where Assembly code is embedded in C# code etc.
