Hi,
How I can put the Flash Animations on the Visual Studio C# .Net form?
Can I put the animated gif image?
Can I use the Flash Buttons?
If answer is YES………then how can I do?

You can use the windows media player control to play movie files. You can use code that's in an article on this site to play animated gifs. You need to visit the flash site to find a control to play flash, assuming that one exists.

Hello,
I am working on a small application coded in C# with multiple forms. This application needs to bring in data from my Access Database. I was hoping someone could point me to a good tutorial or any information that could help me. Thanks!

sConnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Application.StartupPath + "\\DB.mdb;";<br />
INSERT, UPDATE, DELETE DATA
sQuery is the SQL string
<br />
OleDbConnection oleDbConn = new OleDbConnection(sConnString);<br />
<br />
OleDbCommand oleDbCmd = new OleDbCommand(sQuery, oleDbConn);<br />
<br />
oleDbConn.Open();<br />
<br />
oleDbCmd.ExecuteNonQuery();<br />
<br />
oleDbConn.Close();<br />
SELECT DATA
<br />
OleDbConnection oleDbConn = new OleDbConnection(sConnString);<br />
<br />
OleDbCommand oleDbCmd = new OleDbCommand(sQuery, oleDbConn);<br />
<br />
oleDbConn.Open();<br />
<br />
OleDbDataReader oleDbRd = oleDbCmd.ExecuteReader();<br />
<br />
while (oleDbRd.Read())<br />
{<br />
textbox1.Text = oleDbRd.GetValue(0);<br />
}<br />
<br />
oleDbConn.Close();<br />

How can I have XmlSerializer.Deserializer deserialize an array of Category objects? Right now it'll only work on a single Category object.
<categories>
−
<category>
<content-provider-id type="integer">1</content-provider-id>
<id type="integer">2</id>
<name>Traffic Alerts</name>
</category>
−
<category>
<content-provider-id type="integer">1</content-provider-id>
<id type="integer">1</id>
<name>News Alerts</name>
</category>
−
<category>
<content-provider-id type="integer">1</content-provider-id>
<id type="integer">3</id>
<name>testing category</name>
</category>
−
<category>
<content-provider-id type="integer">1</content-provider-id>
<id type="integer">7</id>
<name>curl test</name>
</category>
−
<category>
<content-provider-id type="integer">1</content-provider-id>
<id type="integer">8</id>
<name>sapce test</name>
</category>
</categories>

Assuming that "categories" is your root XML element, then you can do the following:
using System;
using System.Collections.Generic;
using System.Xml.Serialization;
namespace WindowsApplication1 {
[XmlRoot("categories")]
public class categories : List<category> {
}
}
When building your XmlSerializer, you need to specify "categories" as the type like so:
XmlSerializer xs = new XmlSerializer(typeof(categories));

I have a class ServiceResponse that inherits WebResponse. When I create a new ServiceResponse I want to set the base WebResponse with a variable that I pass to the Service Response constructor. How can I do this?
I have this class structure:
public class ServiceResponse : WebResponse
{
public ServiceResponse(HttpWebResponse resp)
{
}
}
/\ |_ E X E GG
|
|
|
|
|
public ServiceResponse(HttpWebResponse resp) : base(resp)
{ //how do I set the base WebResponse to resp? }
this forces a base constructor that takes this parameter to be called.
I'd be surprised if you need this code, I'd expect the base constructor to work, as in
ServiceResponse sr = new ServiceResponse(resp); // I think this should call the base constructor for you but build the derived object )

You can't do that. When the constructor is running, the object is already created, and you are in it.
When you create an instance of an inherited class, there is just that instance. There is no separate base object.
Perhaps you want to encapsulate an instance of the WebResponse class in your class, instead of inheriting from it.

Yeah, I just did this and it seems like a better fit.

Are you looking for something like this?
public class ServiceResponse : WebResponse
{
public ServiceResponse
(
HttpWebResponse resp
)
: base ( resp )
{
}
}

Pretty self explanatory. How do you call from a different class? Thanks in advance -M.S.

If it's a static method, just specify the class name. Example:
Color bg = Color.FromArgb(255, 255, 255);
If it's not a static method, you need an instance of the class to call it. Example:
float hue = bg.GetHue();
(I have used the Color class as an example because it's a well known existing class. The principle is the same for calling methods in any class.)

Or, better yet, use delegates.

No, your question is anything but "self explanatory". You're going to have to provide more details about the problem, 'cause right now, I can see about 4 different situations that would fit your description, none of them the same.
What are the classes?? Which one instantiates the other?? Are you talking about a callback or event?? Are you trying to pass data from one form to another?? ...?? ...??

Call another (whatever this is called) public void (whatever right here) Is that a method, or statement? And I meant self explanatory about the subject, not on difficulty.

So did I. You (still) haven't covered the subject with enough detail to do anything with other than guess at what you want to do.
You declare an instance of a class, which is then known as an Object of type SomeClass, then you call methods of that object.
SomeClass myInstance = new SomeClass();
myInstance.SomeMethod();
int result = myInstance.SomeOtherMethod(someParameter);

I would like to know how to draw a square/rectangle, not filled, and have it move with the arrow keys. I have looked around and everything is just odd, and unworking. If anyone doesn't know how to draw it, that's fine, but I would really apprectiate the movement with arrows. Thanks in advance, M.S.

If a rectangle is a target object, then create a Label control with no text and BorderStyle set to Single. Then handle KeyDown event of the parent Form.
If you are going to expand graphics, then use GDI (Graphics.DrawRectangle(...);), however in such case you will have to invalidate a form in this rectangle (this.Invalidate(rect);) (Another way a rectangle would leave it's trace after a movement).

Hi,
there are four steps to draw something so it becomes visible on the screen:
1.
decide on what object you want to draw; it normally is a Control (e.g. a Panel) or a
Form itself. I prefer to add a Panel to a Form, then draw on the Panel.
2.
create some variables (Rectangle, struct, class, whatever) that hold the parameters of
your drawing. In your case that could be top and left coordinate, and width+height,
or just a Rectangle.
3.
create a Paint handler for that Panel, and do all your drawing in there, using the
Graphics class and your variables.
4.
when you want to animate things, modify the variables and call Panel.Invalidate() or
one of its overloads (for selective invalidation).
BTW: if you need to create some objects (Fonts, Pens, Brushes, ...) either keep them
alive in class members (hence create them only once); or create them inside the Paint
handler and don't forget to call Dispose() on them.

I get this error using this code :
string strSQL = "";
if (klantID > 0)
{
strSQL = "INSERT...";
}
else
{
strSQL = "UPDATE...";
}
The error is on the line where the update-query is assigned to strSQL.
What's the reason I get this error ?
|
|
|
|
|
I don't see how that code can produce that error. Is this the actual code you are using?
|
|
|
|
|
This is the actual code (except for not mentionning the whole query because otherwise it would be too long).
