Check this:
public class Params
{
private static int iParam;
public struct ParamFields
{
public string[] FieldArray;
public const int Value1 = 1;
public const int Value2 = 2;
}
public ParamFields Value(int sequenceID, int routinID)
{
//This is where some action must be carried out before I read Value1 and Value2.
//Using a structure in this way is only way to accoumplish this I think?????
return new ParamFields();
}
}
I use it like this :
------------------------------------
//assume we have Params as object oParam
console.writeline(oParam.Value(10,11).Value1))
------------------------------------
In this example Value1, Value2 is constants but they can change depening on what I pass to Value-function.
My question ... Can I retrieve Value1 by using:
-------------------------------------------------
//assume we have Params as object oParam
console.writeline(oParam.Value(10,11));
-------------------------------------------------
i.e use Value1 as default trough ToString or something else? any suggestions?

Let the struct inherit IConvertible, and implement it's methods. Then the struct can be automatically converted to a string.

b { font-weight: normal; }

Can you give me an example of that? I have no Idéa ... please use my little class.

I was wondering if anyone knew if it was possible to insert text programmatically into a specific position in a richtextbox, that already contains text?
|
|
|
|
|
You Can Insert Text at specific posiotion by do something like that Which will insert the code after the six charachters in richtextbox
richTextBox1.SelectionStart=6;
richTextBox1.Paste();

Hello,
If I have:
dataview.ListChanged += new System.ComponentModel.ListChangedEventHandler(this.dataview_ListChanged);<br />
dataview.Table.ColumnChanged += new DataColumnChangeEventHandler (this.dataview_ColumnChanged);
To unhook those event from my dataview, do I just replace the + sign with -?
Thank you

Yes if you want to unsubscribe to an event use -=

Hello,
I have a datagrid for which I sort a column through code. I don't want the user to able to sort the columns, so I have set the
datagrid.AllowSorting = false;
When I open the form, the user can still sort the columns.
After searching the internet, I've found that if you use TableStyles that you have to set the AllowSorting property of that TableStyle to false, because it overwrites the datagrid's AllowSorting property.
But when I open the form, the user can still sort the columns.
Are there other properties to set to not allow the user to sort?
thx in advance,
kalliet

Figured it out!
I was on the right track (TableStyle.AllowSorting = false), but because I moved the columns I had to create a new TableStyle and I forgot (shame on me!) to copy the AllowSorting property in the new datagrid.
So for any of you who are interested :
if you use sorting on a datagrid and you use TableStyles :
set the TableStyle.AllowSorting property to the datagrid.AllowSorting property, because it overwrite the datagrid's property !!

hi all,
I need to get path of MDF and LDF files of a database("stock") in SQL Server.
Can I get path of both files using C# ?
thanks in advance..

You can easily achieve this by using SQL DMO.
SQLServer2Class sqlServerSource = new SQLServer2Class();
SQLServer2Class sqlServerdestination = new SQLServer2Class();
//Connect to source database
sqlServerSource.LoginSecure = true;
sqlServerSource.Connect(serverName, null, null);
foreach (_Database databaseClass in sqlServerSource.Databases)
{
if (databaseClass.Name.ToLower().Trim() == databaseName.ToLower().Trim())
{
foreach (FileGroup fileGroup in databaseClass.FileGroups)
{
foreach (DBFile dbFile in fileGroup.DBFiles)
{
sourceFileNamePhysical = dbFile.PhysicalName.Trim();
}
}
break;
}
}

Hi what I want to know if it is possible to bind a property of a property to for example a listbox. When I try it comes up with a lot of strange errors. First it tried to show the ValueMember and then it used the qualified name.
The code:
MyListBox.DataSource = MyObject<br />
MyListBox.ValueMember = "ID"
MyListBox.DisplayMember = "SubObject.Name"
|
|
|
|
|
DisplayMember will take the SQL field name. I think you cannot assign field name "SubObject.Name" like this.

This has nothing to do with SQL. The data is coming from a Xml-File. But that is not the point. What MyListBox.ValueMember = "ID" does is bind it with a Property in the already bound MyObject. So the question remains is it possible to use a property of a property as a DisplayMember?

Hello,
I have a window application with a datagrid on it. (Data bound from a dataset). Each row has an order number (stoporder).
Now I want the user to be able to move the rows up and down with an up and down button(and automatically change the number).
I can do this ok, if I manually click the order number first. (Then my rows move up and down and the number alters.) But how can I do this in the code? If I sort on any other column, then the up/down goes wrong too.
<br />
private void btnRouteStopUp_Click(object sender, System.EventArgs e)<br />
{<br />
DataRow row;<br />
int stopOrder;<br />
DataRowCollection rowCollection;<br />
int inc;<br />
<br />
try <br />
{<br />
row = GetRouteStopsRow ();<br />
dtRouteStops.UnSelect(dtRouteStops.CurrentRowIndex);<br />
inc=dtRouteStops.CurrentRowIndex;<br />
<br />
if (null != row) <br />
{<br />
stopOrder = Convert.ToInt32(row[FLD_STOPORDER]);<br />
if (stopOrder > 1) <br />
{<br />
stopOrder -= 1;<br />
row[IMS.FLD_STOPORDER] = 0;<br />
rowCollection = m_dataSetRouteStops.Tables[TBL_ROUTESTOPS].Rows;<br />
foreach (DataRow rowMove in rowCollection) <br />
{<br />
if (DataRowState.Deleted != rowMove.RowState) <br />
{<br />
if ((row != rowMove) && (Convert.ToInt32(rowMove[FLD_STOPORDER]) == stopOrder)) <br />
{<br />
rowMove[FLD_STOPORDER] = stopOrder + 1;<br />
row[FLD_STOPORDER] = stopOrder;<br />
break;<br />
}<br />
}<br />
}<br />
}<br />
}<br />
}<br />
dtRouteStops.Select(inc-1);<br />
}<br />
catch (System.IndexOutOfRangeException ex)<br />
{}<br />
catch (Exception exc) <br />
{}<br />
}<br />
<br />
private void btnRouteStopDown_Click(object sender, System.EventArgs e)<br />
{<br />
DataRow row;<br />
int stopOrder;<br />
DataRowCollection rowCollection;<br />
int inc;<br />
<br />
try <br />
{<br />
row = GetRouteStopsRow ();<br />
dtRouteStops.UnSelect(dtRouteStops.CurrentRowIndex);<br />
inc=dtRouteStops.CurrentRowIndex;<br />
if (null != row) <br />
{<br />
stopOrder = Convert.ToInt32(row[FLD_STOPORDER]);<br />
if (stopOrder < m_dataSetRouteStops.Tables[TBL_ROUTESTOPS].Rows.Count) <br />
{<br />
stopOrder += 1;<br />
row[IMS.FLD_STOPORDER] = 0;<br />
rowCollection = m_dataSetRouteStops.Tables[TBL_ROUTESTOPS].Rows;<br />
foreach (DataRow rowMove in m_dataSetRouteStops.Tables[TBL_ROUTESTOPS].Rows) <br />
{<br />
if (DataRowState.Deleted != rowMove.RowState) <br />
{<br />
if ((row != rowMove) && (Convert.ToInt32(rowMove[FLD_STOPORDER]) == stopOrder)) <br />
{<br />
rowMove[FLD_STOPORDER] = stopOrder - 1;<br />
row[FLD_STOPORDER] = stopOrder;<br />
}<br />
}<br />
}<br />
}<br />
}<br />
dtRouteStops.Select(inc+1);<br />
}<br />
catch (System.IndexOutOfRangeException ex)<br />
{}<br />
catch (Exception exc) <br />
{} <br />
}<br />
Any suggestion?
thx in advance,

what I forgot to add :
dtRouteStops is the name of my datagrid
m_dataSetRouteStops is the name of my dataset
kalliet
|
|
|
|
|
in the load method, I added :
m_dataSetRouteStops.Tables[TBL_ROUTESTOPS].DefaultView.Sort = "stopOrder asc";
The column is now sorted from the start, which makes the up/down go OK.
Now I have a new problem : how do I set the grid on sorting not allowed? (so the user cannot sort on other columns)
I've tried the property :
dtRouteStops.AllowSorting = false;
but when the form appears I CAN sort on columns of the datagrid ????
any ideas?
thx in advance,
kalliet
