If, as you said, it was an example for others then you shouldn't post a one that is so obviously wrong. Bad examples lead to bad developers following.

System.Diagnostics.Process.Start(@"myUrl");
Right - you use a quoted string there not a variable. That's what is wrong - if you type this in and try to run it, it's not going to understand what you are trying to do. How could it?

Well it is true that "really hard to find" is relative. I always used to hear that there were some people that could not find their way out of a wet paper bag. Now it never seemed to me like that would be to difficult, but then I've never been in one.

Hi All,
Can anyone tell me how set a image on the header of a CrystalReport object programmaticaly?
Thanx
|
|
|
|
|
I could have sworn CrystalDecisions.CrystalReports.Engine.PictureObject had some properties that allowed you to change the image. Either I'm mistaken or I'm looking at the wrong class.
One way I've done what you're asking for in the past is simply passing the image as a byte array inside a dataset.
First convert:
System.IO.MemoryStream _mystream = new System.IO.MemoryStream();<br />
_mypicture.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);<br />
_mystream.Position = 0;<br />
byte[] _mydata = new byte[stream.Length];<br />
stream.Read(_mydata, 0, (int)stream.Length);
Then add to a data table in your dataset:
_mydataset._mydatatable.Rows[0]["PictureColumn"] = _mydata;
This assumes you're also binding your data through your app. If you're pulling straight from a database, just put the image in a datatable on the database and pull it from there.

Once you add the image column to one of the tables in your dataset, preferably in a table that only has a single row returned. Update the CrystalReport in the designer by refreshing the dataset in the Database expert.
After you do this, you can drag and drop the image into the report as you would any other field.

hii,
Im developing an client server application in C#.
In that i have to use Mobile Agent technology.
On the Server side there is a class...which i want send to the client...by System.IO class..let the class be Mobile...and it has a methode mobilecode()
public class Mobile()
{
public void mobilecode()
{
Code for gathering data from client.
}
}
On the Client side i read this file by stream reader...and i save this class in the same directory of the client.cs project..
on main function of client.cs
i call the class by...
Mobile.mobilecode();
but while compiling..it gives the error...
Mobile doesnt exist...
even if i make an empty class Mobile...thinking it could b overwritten by the code sent from server...dat does not happen...on runtime it reads the same old file...and not the does not updates till the code is executed.
So can anyone help me ou here...as to how to send a class file 4m server to client at runtime and access it immediately at runtime...!!
any help wud b appreciated...
Thnx in advance,,,,!!

creating class is not enough. You should create an object an then use it.

your question was also an elementry one. so I suggested you to read basics before going to complex problems. Anybody with a basic OOP idea can determine that you have to create an object before using properties of that class. That elementry article helps solve your basic question.

Hi,
I am using this line in the code,
ActiveDs.IADsADSystemInfo oSysInfo = new ActiveDs.ADSystemInfoClass();
string temp = oSysInfo.UserName;
This execution works fine on a few systems and for the other systems (few Laptops) it gives the following error "Insufficient memory to continue the execution of the program";
Can you tell me how to resolve this error?
Also, is there another way to find out the CN in ActiveDs.IADsADSystemInfo.UserName in the active directory?
Thanks for your help,

hi friends,Good Evening!!..how can i build an assembly on my own in vs2005.im using webforms.Please explain it in simple steps ,friends.Thank you in advance
Hi,Im Razana
|
|
|
|
|
I'm sorry, but your question doesn't make too much sense. Do you want to know how to trigger a build off the build menu? Or about MSBuild?
|
|
|
|
|
No friend,I just wanna create a shared assembly in c#2.0.
Hi,Im Razana
|
|
|
|
|
Still. What do you mean? What is your exact problem? That's still too vague and open to interpretation.
|
|
|
|

I suppose you want to create a dynamic library (DLL) to share your classes and methods. Then make a new "C# Class Library" project in VS. Do some coding, compile and add it to another project(s) as a reference.

Hello...
private void button1_Click(object sender, EventArgs e)
{
Invoke(new MethodInvoker(MyMethod));
}
or...
private void button1_Click(object sender, EventArgs e)
{
if(InvokeRequired)
{
Invoke(new MethodInvoker(MyMethod));
}
else
{
MyMethod();
}
}
What are the differences ?
Why should I use "InvokeRequired" ?
I can use Invoke method in main thread and another thread also.

Hi,
first of all I think you have choosen a bad example. When receiving a Click event of a button it is clear it will be in the same thread as the container was created in.
Now to your question:
Invoke delegates a call into the thread the control was created in. This is necessary as Windows can react in confusing ways when it is not done. The InvokeRequired version will only do this when it is necessary. If the caller is already in the correct thread it will return false and thus call the method normally. As Invoke is rather expensive compared to a normal method call this might give you a performance benefit. But if you are sure that it is always needed the extra InvokeRequired call might also reduce performance.

Hi,
I created a Dialog box in c#/.NET and I tried to retrieve a data from a combo box present in that Dialog box. I am able to retrieve data using a Property. But at one point of time, I am getting an InvalidOperationException.
Can anyone help me out!
here is the code...
PanelSelectDialog dlg = new PanelSelectDialog();
dlg.ShowDialog();
if (dlg.DialogResult == DialogResult.OK)
{
str = dlg.SelectedPanel;
MessageBox.Show(str);
}
...
...
public partial class PanelSelectDialog : Form
{
public PanelSelectDialog()
{
InitializeComponent();
PanelList.Items.Add("hi");
PanelList.Items.Add("bye");
}
public String SelectedPanel
{
get
{
return PanelList.SelectedItem.ToString();// PanelList is the
//name of combo box
}
}
}
}
Thanks in advance
