Try to put your method in a separate Thread.

You could check the connection status in a timer tick (quick and dirty) or a separate thread (recommended).

I think UI thread doesn't get time to redraw.

On every updation of status put the following code

<br />
yourLabel.Text="status";<br />
mainForm.Refresh();

this refresh method will repaint the GUI

Dim hash As String = FormsAuthentication.Encrypt(ticket)
Dim cookie As New HttpCookie(FormsAuthentication.FormsCookieName, hash)
Response.Cookies.Add(cookie)
FormsAuthentication.RedirectFromLoginPage(TxtLoginID.Text, True)

Unicode in c#.net 2005?

hai all,
is there any particular function by which i can directly use unicode in API..
for eg:
TextOutA(hDevice, sXPos, sYPos, StaticObjects.gtSizeName[lIndex], StaticObjects.gtSizeName[lIndex].Length);

here can i use language "HINDI" for [lIndex]...i tried but it is giving "???" in the places where "HINDI" language is used while running.

There MUST be an easier way to do this!

Hi,

Here's the code (and it works):

< --snip-- >
string deleteStateName = "Bullamakanka";

// find the StateID for the record to be deleted
foreach(DataRow dataRow in newStateDataSet111.Tables["States"].Rows)
{
string StateName = (string) (dataRow["StateName"]);
int StateID = (int) (dataRow["StateID"]);

if (StateName == deleteStateName)
{
deleteStateID = StateID;
}
}
< --snip-- >

There is either a simpler way of achieving this without looping thru each record or I have structured the whole programme incorrectly.

I've read, read and re-read all I can find on the net in regards to datasets and understand how to create them and save changes to them BUT I cannot figure out how you can easily locate values of fields within them to enable me to easily manipulate the row concerned. I'm very frustrated bcause I know the answer to the meaning of life Big Grin | :-D

and feel I'm on the brink of yet another major revelation!

Pointers will be appreciated to any articles written in laymans terms so I can understand it all please.

TIA.

Thanks for that - I just knew there would be.

Now - how did you know to use

Robert Rohde wrote:
'" + deleteStateName + "'

because it's not obvious to me how all the ' and " and + actually converts the variable into what is/was required for the expression Confused | :confused:

.

Your help is much appreciated.

Hi,

have a look here[^]. It covers most things you can do with Select. It can also be used as a reference for the DataColumn.Expression and DataView.RowFilter properties which take similar expressions.

Hi,

I actually found this link sometime late Saturday after my original post. After much reading (and testing) I found I couldn't pass a variable to the expression - I kept getting a "column doesn't exist", cast error or similar. Hard coding worked.

What you showed me was how to use the single quote, double quote and the plus sign to get the variable into the expression. Not just there either - I didn't know how to use a variable in a messagebox text area until you showed me.

I have a couple of books on C# / VS2003 and neither go into any depth at all on this and I was wondering if there is any other source on the net where these obviously essential snippets can be found.

One real problem I'm having is using the right phraseology to locate the relevant help on the net!

Again - thanks for you help,

Regards,

Equivalent of OLE_PropertyPage

Hi,

I have a Dialog based Application and I want to achieve the following thing:

I have a certain area described by a Panel and want to insert there several subforms according to a selected function. I tried to generate a Page as WinForm and set the Parent to the Panel Control, but this didn't worked out. How can I generate several subforms and display them in a clientarea in my main application form.

In usual Win32/ATL this was done with OLE_PropertyPages. Is there any equivalent I'm missing at the moment ?

Bye,
Florian

Maybe you are looking for "User Control" which are in the "Add Item" window.

In .NET 1.1 you cannot change the tab color. But see this:

.NET TrackBar!

Is there a way to keep the trackbar that .net provides and somehow keep the tickstyle in both since i love the way the tracker looks that way but still remove the ticks? I mean that i would like a TicksVisible property like! I think that something like this exists in delphi if i am not mistaken.

Hi,

you can set the TickStyle property to None.

Hey all,

After installing the latest version of the Symbol SDK it seems to have setup a requirement to install the framework on each deploy so debugging is becoming a pain especially when I have to cancel the installation on the handheld each debug.

If you hadn't already guessed, i'm using VS 2003 and I cannot find anywhere that states where these files are, although I know "where" they are, and I have deleted them. But now I receive an error on each deploy stating it cannot find these files.

Sooooo, does anyone know where the hell these files are referenced?

TIA

sql command for INSERT ...

hi all,
there is 2 table (maintable[numdoc_id,...]) and(subtable[id,numdoc_id,...])and there is a one to many relation between 2 table .
in the MainForm :

...<br />
private int get_num_ID;<br />
...<br />
private int NUM_MY_ID(out int MY_ID)<br />
   {<br />
    ...<br />
    strFindID = "SELECT MAX(numdoc_id) as numdoc_id FROM MainTable";<br />
    ...<br />
    MY_ID = Int32.Parse(ds.Tables[0].Rows[0][0].ToString());<br />
    MY_ID++;<br />
    return MY_ID;<br />
    }

and for Insert Function in MainForm for subtable :

private void ADD_INTO_SubTable()<br />
   {<br />
    ...<br />
    try{<br />
    strSQL_P = "insert into subtable(numdoc_id,...)";<br />
    strSQL_P +="value('"+txtnumdoc_id.Text+"',...)";<br />
    ...<br />
    }...<br />
   }

and for Update Function in MainForm for subtable :

private void Update_INTO_SubTable()<br />
   {<br />
    ...<br />
    NUM_MY_ID(out get_num_ID);<br />
    try{<br />
    strSQL_P = "update payment set numdoc_id='"+get_num_ID+"'";<br />
    strSQL_P += ... where numdoc_id=" + get_num_ID;<br />
    ...<br />
    }...<br />
   }

txtnumdoc_id control is in MainForm(for maintable), but sometimes when I click the save button in main form ,the first numdoc_id row in maintable(e.g. '1') is added to the last row for subtable in numdoc_id field . I don't know where is my wrong .

hi there !
when I Insert a record in the MainTable , at the same time a record must be added to the subtable with the same Id(numdoc_id) , (there is a relation one to many between them )but sometimes , it doesn't happen . and the only the first id of the maintable is added to the last record of the subtable .
Is it clear or not ?
