Pleasae can someone help me. I have created a custom ribbon and am trying to implement it in an ExcaleAddIn and have created all the neccessary xml for it along with it's events as follows:
<pre><?xml version="1.0" encoding="UTF-8"?>
<customUI onLoad="Ribbon_Load" xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon>
<tabs>
<tab idMso="TabAddIns" label="ValueExplorer">

<button id="btnSysConfig" onAction="btnSysConfig_Click" label="System Config" showImage="false" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>

I have also created the callbacks for the OnAction event as such:
<pre>public void OnActionCallback(Office.IRibbonControl control, bool isPressed)
{

if (control.Id == "btnNewVersion_Click")
{
//MessageBox.Show("You clicked " + control.Id);
Form frmNewModel = new Form();
frmNewModel.Show();
}
else
{
MessageBox.Show("You clicked a different control.");
}
}

But i still can't get any functionailty out of it. I have successfully added the ribbon to the workbook as a tab but also have some default menu items displaying even after setting the StratFromScratch property to true.

Please help where you can.

Thanks

Hi,

I have extended the griview to open in edit mode for all of the rows. After changing in few cells (text boxes) in some of the rows, I want to know which row has how many columns changed by the user. If no cell is changed in the row, the row number should not be returned.

Can any one help me to know which are the cells that changed when the Gridview is in edit mode. Any poniters or hints will help.

Thannks in advance!

If you want a unique number, how about using GUID. It's simple and unique.

How about just increasing the number:

Student 1 : 00000001
Student 2 : 00000002
...
Student 99999999 : 99999999

If you want to add a new student, just get the record from database.
For example, the last record is number "10".
Then just give number "11" to the new student.
It's so easy.

The right way is to add a number automatically in database. It increase the number automatically
and the number is a primary key. That means the number is unique.

I would suggest storing the number in a file outside your app and then read that number when processing a form. Once form has been processed just update the number to the next. This is how I currently do it to store version numbers for batch files generated from my apps.

Are you storing the information in a database? If so, get the database to create the id for you. Make the primary key (the registration number) an identity column and your registration number will be generated upon insertion to the database.

If you storing the information in some other manner, you'll need to just build a counter to increase the registration number by some amount (could be 1, could be more in order to validate a number as a valid registration number and avoid typos) each time. If this is a serious application then you'll need to make sure you do this in a common place (singleton) and that this action is threadsafe.

specify url in app.config

Hello,
I want to edit an existing app.config file with a modified url. The URL points to an intranet site which fetches list of documents.
If i copy the link from address bar(correct address) and paste in app.config to replace the existing url, i get errors. It says to use ; after some some particular words and if i do so, it says that entity not defined.

The updated URL is like this
http://XYZ/TestSoftware/buglist.cgi?query_format=specific&order=relevance+desc&bug_status=__all__&product=Test%3A+Application&content=

And the words are query_format,order, bug_status, product, content.

What to do?

Thanks in advance.

The app.config file is just an XML file. Therefore you have to respect all the rules that XML puts in place. You must escape certain characters such as & to &

Comma as Decimal Symbol creating problem

Hi All,

I have a windows appliation.

It creates problem when it runs with Dutch(Belgium) or some other language settings that set Decimal Symbol as Comma(,) and Digit Separator as Dot(.)

Due to such settings, number like 2.22 or 22.2 will be considered as 222.

Is there any way to run .net appliation under default English(US) settings irrespective of settings of Regional and Language Options? Without changing global settings on user's PC?

Regards,
-SIFAR.

Place this code under your main class.

//Force application to use culture En-US.<br />
          System.Globalization.CultureInfo cultureInfo = System.Globalization.CultureInfo.GetCultureInfo("en-US");<br />
          System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;

happy coding...

Serialize/Deserialize data class from different assemblies

Hi gurus,

I'm new to .NET Remoting and I have this problem.

I have an assembly, API.dll, that contains all the abstract functions and data classes.
I have a separate assemby, APIImpl.dll, that overrides the functions and data classes.

Let's focus on my this one:
One of my abstract data class in API.dll is read-only, meaning it only have the getter.
The setter of this data class is in APIImpl.dll.

I wanted to implement remoting to cater for some requirements. I made all my data classes Serializable. However, when i tried testing the remoting that i implemented, I encountered a SerializationException and the message is 'Unable to locate APIImpl.dll'.

From what I understand about remoting is that the implementation dll does not necessarily to be in the client machine. But base on the exception that I encountered, in the client application it's still searching the implementation assembly.

Please help. Frown | :(

Thanks in advance.

A serialized class stores full names or your class and the properties of this class.
If your server serializes a class of your Apiimpl.dll than this assembly name is stored within the full name of the class. So for deserialization this assembly must be present on your client.

A common way is to use interfaces:

// API.dll:

public interface IDataClass {
  int DataField { get; set; }
}

// APIIMPL.dll:

public class DataClass: IDataClass {
  private int dataField;

  public int DataField { get { return dataField; } set { dataField=value;} }
}

So on your client is no code from your server. This works the best.

Try out the xml serialization to see and understand whats happened to your classes during serialization (search for XmlObjectSerializer in your msdn library).

hi occcy,

thanks for your explanation.
that's the way i understand it also.

but the current project that i'm working on, in the interface/abstract class they only have the get. then the set is in the implementation dll.

// API.dll:
public interface IDataClass {  
   int DataField { get; }
}

// APIIMPL.dll:
public class DataClass: IDataClass {  
   private int dataField;  
   public int DataField { get { return dataField; } set { dataField=value;} }}

is there any tweak that i can implement for this to work in remoting??
