I have tried the following code....

private void GenerateTable1()
{
Table table = new Table();

table.ID = "Table1";
Page.Form.Controls.Add(table);

const int colsCount = 6;

TableRow row = new TableRow();

for (int j = 0; j < colsCount; j++)
{

TableCell cell = new TableCell();
if (j == 0 || j == 2)
{
Label lbl = new Label();
//lbl.ID = "LabelRow_" + 0 + "Col_" + j;
if (j == 0)
{
lbl.Text = "Acc No";
}
else
{
lbl.Text = "Vol";
}
cell.Controls.Add(lbl);
row.Cells.Add(cell);

}

else if (j == 1 || j == 3)
{
TextBox tb = new TextBox();
//tb.ID = "TextBoxRow_" + i + "Col_" + j;
cell.Controls.Add(tb);
row.Cells.Add(cell);

}
else if (j == 4)
{
Button btn = new Button();
btn.Text = "Add";
//btn.Attributes.Add("onclick", "MyFunction()");

cell.Controls.Add(btn);
row.Cells.Add(cell);
//btn.Attributes.Add("onclick", "this.visible = 'false'");
//btn.Click += new EventHandler(this.Button1_Click1);

}

else
{
Button btn = new Button();
//btn.ID = "ButtonRow_" + i + "Col_" + j;
btn.Text = "Remov";

cell.Controls.Add(btn);
row.Cells.Add(cell);
}

}
table.Rows.Add(row);

}

=====================================================================

now I want that the dynamicaly created button ADD should add next row of same kind and dynamicaly created button REMOV should delete perticular row..

plz help me...

Bits and Bitmask - how to write?

Hi,

I am unfortunately not familiar with single bits and have now the problem that I have to write single bit values in an integer value.
The bit masks look like:

Value#   Bit    Mask
1        2-0    00000007H
2        5-3    00000038H
3        8-6    000001C0H
4        15-9   0000FE00H
5        22-16  007F0000H
6        29-23  3F800000H
Bit 30-32 are unused.

Does anyone know how can I set these six values - maybe as short example?

Many thanks! Daniel.

You mean like this?

int x = 0;
x |= 7; //set lowest three bits
x |= 0x3F800000; //set bits 23 through 29
x ^= 0x38; //invert bits 3 through 5
x &= ~7; //clear the lowest three bits

thank u harold!

but sorry, i can not understand your solution because you use always 'x' as variable and overwrites therefore all previous values.
can you give me more details?

so far, i can read the values i.e.:

int[] fieldvalue = new int[6];
    fieldvalue(0) = (67637321 & 0x7) >> 0;
    fieldvalue(1) = (67637321 & 0x38) >> 3;
    fieldvalue(2) = (67637321 & 0x1c0) >> 6;
    fieldvalue(3) = (67637321 & 0xfe00) >> 9;
    fieldvalue(4) = (67637321 & 0x7f0000) >> 16;
    fieldvalue(5) = (67637321 & 0x3f800000) >> 23;

so the first three values are set to 1 and the last three to 8.

how can i now set the second value i.e. to 2? or in other words: how do i get the int value 67637321 if i have as first three value 1 and as last three 8?

many thanks!

int value = fieldvalue[0] | (fieldvalue[1] << 3) | (fieldvalue[2] << 6) etc

Just shift the bits back to their original position, and OR them together.

Hi,

here are some elementary operations:

1.
bitnumber to bitmask: mask=1<<number;
inverse mask:="" inversemask="~mask;

2.
bitnumbers" to="" bitsmask:="" mask="(1<<(numberHi+1))-(1<<numberLo);" example:="" 2="" and="" 0="" yield="" 7

3.
hex="" output:="" string="" s="number.ToString("X8");

4.
extract" bit="" from="" number:
bool="" bitisset="(value" &="" mask)!="0;

5.
extract" bitfield="" number:
int="" fieldvalue="(value" mask)="">>bitnumLo;

6.
replace bit in number:
mask=1<<bitnum;
notmask=~mask;
value=value&notmask;
if (newbitset)="" value|="mask;

7.
replace" bit="" field="" in="" number:
mask="(1<<(bitnumHi+1))-(1<<bitnumLo);
notmask=~mask;
value=(value&notmask)" |="" (newfieldvalue<<bitnumlo);

btw:="" using="" more="" parentheses="" than="" strictly="" necessary="" to="" keep="" expressions="" unambiguous="" for="" human="" reading.

You paste the control into RDLC and hope it will replicate automatically. Poke tongue | ;-P

Place the textbox inside a List or Table. And also make its value as Field!FirstName.Value(just leavethe First() out of the value)

You are done.,. .

Starting a new process after process.close()

Member 37222616-Sep-09 5:14

Hi All,

I have a c# winforms application.
I want to give the relogin feature with a full logout and
relogin again.

so I need to start a process after I close the current process.

Today I implement this code:

<br />
Process process = Process.GetCurrentProcess();<br />
<br />
process.Close();<br />
<br />
Process reloginProcess = new Process();<br />
<br />
reloginProcess.StartInfo.Arguments = string.Format("{0} {1}", _userName, _password);<br />
<br />
reloginProcess.StartInfo.FileName = AppDomain.CurrentDomain.BaseDirectory + @"g2gg2.exe";<br />
<br />
// call start process<br />
reloginProcess.Start();<br />
<br />

In some stations(all win xp) I get exception, I think its because the first process fail to close.

Do you have a better way to start the second process (File + Arguments )

Thanks!!!
Ronen

I think it would be a good idea if you read up on what a process is. And then changed your plan somewhat.

Member 3722261 wrote:
Process process = Process.GetCurrentProcess();

process.Close();

Process reloginProcess = new Process();

Doesn't this strike you as at all unlikely to work?
What happens when you stop the current process?
What should execute any further instruction when the process which is executing the instructions is no longer running?

Please, do not go near any buttons marked "Do not, under any circumstances, and I mean any circumstances, press this button. I mean it. The world will end if this button is pressed. So don't press this button." - you strike me as the kind of person who views that as a challenge... Laugh | :laugh:

So what is the best implementation to start a new process at the
end of the current one?

Thanks again.

Did you find out what a process is?
What happens when you stop the current process?
I'll give you a hint: In the previous question, replace "stop" with "saw off" and "current process" with "branch you are sitting on".

Re-think what you are trying to do. Stopping a process (particularly the current one) is not a solution to your problem, it is a whole new world of pain all of it's own. Think about what you are trying to achieve, and how you would do it in the real world - ignore computers. If you want to read a different book, you don't start by burning down the library to get rid of the previous one, do you?

OriginalGriff,

I'm using close not Kill.
Close - Frees all the resources that are associated with this component.

so what is so wrong by opening a new process as the last action of current process. I dont think its like your library folk tale .

Thanks!

Re: Starting a new process after process.close()

OriginalGriff6-Sep-09 23:52

Kill is intended for non-gui processes, and for abnormal termination. See documentation[^]
Close[^] does much the same thing (normally after CloseMainWindow) but does not loose resources.
You still cannot close or kill your own process! You can restart it, but if you close or kill it it stops existing.

You will be amazed by the things you can do after calling currentProcess.close().

Check it out...

Hi,
I think System.Windows.Forms.Application.Restart() is what you are looking for. The docs explain the intended usage.

Hi,

but I think that Application.Restart wont help me because my process has alot of static "junk" that I want to clear. that the reason I need to start a new process.

Am I right?

Thnaks!

Hi,

Static members on some objects.
Static cntor
...

All static belong to the process so my Q is if all will initialize again?

Hi,
Yes, it would do that as it terminates the old process and starts a new instance.

Is it possible to call a function from an external DLL from C#.NET code. If needed I would use LoadLibrary and GetProcAddress. It would be better if it could be linked at Program Loading.
