As someone else said, instead of having 100 fields, have a collection which contains them ( and if they are named card1-card100, an array makes sense, you just put the number in the indexer ). Then you can iterate over them with foreach to do your test.

Hello. I have a combobox with a couple of items in it. Instead of having a label on the form that describes the content of the combobox id like to use the textproperty for this purpose. So far so fine. But now I want to change the textproperty of the combobox to italic but leave the rest of the items in the combobox as regular text. Anyone knows how I can do this.
As it is now when i change the combobox.Font.Italic prop all the items in the collection is set to italic.
//Thx

It's all or nothing using the standard control.
If you wanted more control over the textbox and the list fonts, you'd have to create your own version that supports this, supplying the properties to be set for each side of the control and supplying all the rendering code to draw the textbox and the drop down list.

I have a program that will connect to an FTP site with InternetConnect() if I use my Windows dialer.
If I try to connect to the FTP site using another dialer there is no connection to FTP site.
My Windows dialer has my user name and password for my ISP, but the other dialer does not, it just dials and connects.
I am confused, how can the other dialer connect without my ISP username and password? This is probably why I cannot connect to FTP site.
I can make a connection with the other dialer using HTTP settings and using a www.myspace.net address, but if I switch over to FTP settings and use ftp.myspace.net, no connection.
Please excuse me if I sound confused, I am, and I can't seem to get my brain wrapped around these concepts.
Thanks for any help.

Hi,
Is it possible to assign a null to a DateTime value type? If not, what then?
Regards

No, it's not.
You can only assign null to a reference, and as DateTime is a value type, there is no reference.
ma se wrote: If not, what then?
If you are using framework 2.x, you can use the nullable types:
DateTime? when;
if (something) {
when = null;
} else {
when = DateTime.UtcNow;
}
if (when.HasValue) {
Console.WriteLine(when.Value.ToString("yyyy-MM-dd"));
} else {
Console.WriteLine("No time specified.");
}
If you are using framework 1.x, you have to do something else to keep track of when there is a value or not, like using a bool variable along with the DateTime variable.

Thanks for the reply, but I struggle to see where you assigned it a nullable value?

It's the question mark behind the type name.

You can solve this with a nullable type (since .NET 2.0)
or you might be able to set aside one value and let it represent the "has no value" situtation;
in case of DateTime it probably would be DateTime.MinValue

Winforms .net 2 application is running a bit slow.
How to find which methods take most of the time?
I'm using Visual C# 2005 Express Edition.
I havent found any way to create list of executed method calls ordered by execution time.
There a a lot of PostgreSQL database calls to show report.
I think some database calls take too lot time in summary.

I would say that it's most likely that the performance problems are in the sql queries, at least without seeing any of the code.
The SqlConnection object can collect statistics about all queries made with it. Check if the connection object that you are using has something similar.

I checked NpgsqlConnection object documentation.
I does not contain any method for statistics collection.

I would like to know how to search for a certain record by a value in a non keyed column, then being able to update that record to the values in another table. Here is what I have used in the past to locate a record by a primary key, is there a way to do the same with out a keyed column as a search value.Do I need to set the primary key temporarily to the new column I need to search?
DataSet1.HorseJoinTableDataTable dth = new DataSet1.HorseJoinTableDataTable();
DataSet1TableAdapters.HorseJoinTableTableAdapter tah = new FBWinMobileSync.DataSet1TableAdapters.HorseJoinTableTableAdapter();
dataSet1.EnforceConstraints = false;
tah.FillByMod(dth);
fB7MobileDBDataSet.EnforceConstraints = false;
foreach (DataSet1.HorseJoinTableRow dr in dth.Rows)
try
{ How can I accomplish this below on a non keyed column search
FB7MobileDBDataSet.HorseRow newMobileHorse = this.fB7MobileDBDataSet.Horse.FindByCODEHorseName(dr.CODE, dr.HORSENAME);
newMobileHorse.CODE = dr.CODE;
newMobileHorse.Stable = dr.STABLE;
newMobileHorse.HorseName = dr.HORSENAME;
newMobileHorse.Active = dr.ACTIVE;
newMobileHorse.AngleLF = dr.ANGLELF;
newMobileHorse.AngleLH = dr.ANGLELH;
newMobileHorse.AngleRF = dr.ANGLERF;
newMobileHorse.AngleRH = dr.ANGLERH;
dataSet1.EnforceConstraints = false;
//if(dr.DUEDATE.ToString().Trim()=="")
if (dr.IsNull("DUEDATE"))
dr.DUEDATE = DateTime.Today;
newMobileHorse.DueDate = dr.DUEDATE;
if (dr.IsNull("LASTCOST"))
dr.LASTCOST = "0";
double D = Convert.ToDouble(dr.LASTCOST);
newMobileHorse.LastCost = D; //Convert.ToDouble(dr.LASTCOST);
newMobileHorse.Totals = 3;
//Equals no change to record
if (dr.IsNull("LASTDATE"))
dr.LASTDATE = DateTime.Today;
newMobileHorse.LastDate = dr.LASTDATE;
newMobileHorse.LengthLF = dr.LENGTHLF;
newMobileHorse.LengthLH = dr.LENGTHLH;
newMobileHorse.LengthRF = dr.LENGTHRF;
newMobileHorse.LengthRH = dr.LENGTHRH;
newMobileHorse.MainWork = dr.MAINWORK;
newMobileHorse.NickName = dr.NICKNAME;
newMobileHorse.SizeLF = dr.SIZELF;
newMobileHorse.SizeLH = dr.SIZELH;
newMobileHorse.SizeRF = dr.SIZERF;
newMobileHorse.SizeRH = dr.SIZERH;
newMobileHorse.Weeks = Convert.ToInt16(dr.WEEKS);
newMobileHorse.Delete = dr.DELETE;
newMobileHorse.LengthList = dr.LENGTHLIST;
newMobileHorse.NeedsNewFr = dr.NEEDS_NEW_FR;
newMobileHorse.NeedsNewHd = dr.NEEDS_NEW_HD;
newMobileHorse.StartAngleLF = dr.START_ANGLE_LF;
newMobileHorse.StartAngleLH = dr.START_ANGLE_LH;
newMobileHorse.StartAngleRF = dr.START_ANGLE_RF;

newMobileHorse.StartLengthRF = dr.START_LENGHT_RF;
newMobileHorse.StartLengthRH = dr.START_LENGTH_RH;
newMobileHorse.Front = dr.FRONT;

DataSet ds = new DataSet();
DataTable table = new DataTable();
ds.Tables.Add(table);
DataRow rows[] = table.Find("MyField = 'Hello World');
That should do the trick.

I am using a Repeater to make a menu off a SiteMap. I also made a custom user control that is a cool looking button. The button's events work fine and the properties work fine as long as I am not in a repeater control. If I use the repeater control I get a NullReferenceException because as far as I can see all my properties are null on postback.
How can I get all my properties to save?

Found the solution. I had to go add ViewState objects to my custom control to get it to have ViewState properties, I assumed it would do it itself, I don't know why I made that assumption.

Iam currently in the middle of writing a screen grabbing app in c#. One of the requirements for the application is that the form or window of my application doesnt appear in the grabed images. Under XP this was easy as I just set the form to not appear in the task manager in the form properties in visual studio and when it was minimised you couldnt see it at all.
The same nearly applies to vista, I cant see the window when minimised and it doesnt appear on the taskbar. However when it is minimised I seem to get a floating tab of the window in the main desktop.
I dont know if this can be disabled with a vista control panel setting or there is some other way of doing it with code but I cant seem to find it either way. Can anyone possibley help with this.
Much appreciated Mike
