If i understand you correctly you went to Access Db and Opened it and change or added new columns and when you say it does not reflect in your project what do you mean ? please explain that part.

Re: changing the database after addition to the project ?

26-Mar-09 5:01

exactly .... and does not reflect the changes means that in my project the database in the right side in visual studio is not showing the modified tables i mean the new tows which i have added to the table...

Delete the Connection and recreate it , it should appear. But before you do that try to refresh it first from the Server explorer. i dont use Wizards for my database work.

Performance problem when implementing driversin state machine model

Hi,

I have implemented a device driver in state machine model using C# i.e based on the previous states output new state has to be initiated in one module.in every state i am sending info to Reader connected through serial port.Timer will be running parelally and checking for the data received event of Serial port and once data received state will be moved to nextstate.Its working fine but very inconsistent.Say executing some states and stopping there and waiting for the reply from Serial port.I cant understand whether its Timer problem or serial port problem.Can any one please reply .I will post the code used here which i used for stop module.

private void tmrCOMM_Tick(object sender, EventArgs e)

{

try

{

tmrCOMM.Enabled = false;

#region " Timeout "

if (blnCheckTimeOut)

intTimeout++;

AddLog("Timeout, no response from reader!");

intState = STATE_NOTHING;

tmrCOMM.Enabled = true;

blnCheckTimeOut = false;

Array.Resize(ref gblbMsgIn, 0);

return;

}

}

Rightclick on the solution in the 'Solution Explorer', and choose "Properties". Go to the tab labeled "Application", and verify that you have assigned an icon to the application (not just the mainform, as the mainform.icon != app.icon)

I are troll Smile | :)

there is an Icon property of form, you have to change it for each form.

Thanks for reply Xmen!!!

This also does not work

i have done what yous said for each form in my application with addition to ShowInTaskBar property to true

however icons disappears from task bar when two or more forms are opened in the application specifically OS creates the stack(Re-groups) if other more applications are opened, and this time the icon of the stack representing my application change to icon which we can see when we choose new icon file in the Visual studio

What are you creating your Icons with? As far as i know windows requires different size icons for different things. i.e. you need to create an icon that supports multiple resolutions in order for them to be displayed in all instances.

Check this[^] out; its free, and always works for me Smile | :)

thanks musefan!!!

I was creating the icon form VS-2005

I did not used any other utility to create icon

let me use this and check if it works

anyways thanks for exploring with this tool

Thanks Eddy for reply!!!!!

This seems does not work.........

solution provided by you works only to show the icon in the task bar but not when
two form are opened or in the list appears after pressing ALTER + TAB keys

In my case what you have provided is done already but still facing the same problem

I thing either this is the bug in installer provided by the .net or it has to do with something with OS or with ICON size (as desktop icons are 32x32 and startup->program file,control panel->Add/remove program,taskbar icons are of 16x16)
I am not sure about this

what do you say??
