Thanks for your suggestion ES, that worked for me. Could you please tell me how to dispose the client object in SendCmd button click event. I tried using Client.Dispose() method, the object is not getting empty.

The following query which i tried:

SELECT tl.TESTID INTO testID FROM TESTLIB tl
WHERE tl.DBDESCRIPTION = LDescription;

SELECT tlv.testrevid INTO testRevID FROM TESTLIBREVISION tlv
where tlv.revision = 2 and tlv.testid = testID;

It throws error. Is it because i am taking testID from 1st query & using it in the 2nd query...?

Thanks Animesh Datta, but whhen i click on the row header to sort the sorting happens for that particular column & data in other column disappears. Why such a thing happens..?

Jagadisha_Ingenious 24-Jun-16 5:14am View

Ya it will sort but data in other columns disappear why...?

Jagadisha_Ingenious 11-Apr-16 3:26am View

Hi Hiren Soni, these two columns are null.

@Wes Aday: I am not making any conversion to the table but still i get this error. I have identity column in the table, if remove it by commenting the line of code it works fine.

@Sergey Alexandrovich Kryukov: I have used system timer to achieve even flashing of the backcolour of the button. I have an array of buttons in the UI which should work accordingly to data i get from the serial port class. By using thread how to can i achieve this changing of back color of button in certain intervals, like i have used the timer interval also to set the flashing rate of the button back color.

Jagadisha_Ingenious 26-Jul-14 2:15am View

@Sergey Alexandrovich Kryukov: I have a windows form & in which i have a serial port class which is running on a different thread. Through this class i am fetching data & based on the data i m receiving certain actions are performed in UI to alert the user. So flashing of button backcolor is one of the method i have used, so for flashing i have another thread & this inturn invokes a timer (from toolbox) for consistent flashing of the button. Which i am not able to achieve due to some reason which i am not able to trace it.

@Emre Ataseven: As per your instructions i did move the file to MyDocuments folder & checked it works out. So how do i place this database file in target machine's MyDocuments folder while creating the exe file.

@Wes Aday: I have not disable or made read only. As u can see i have mentioned that it works through menustrip newfile click event & not through toolstrip newfile button.

@Sergey Alexandrovich Kryukov: I have also used status bar in mdi parent & displaying childform in maximized state due to which the controls that are placed @ the bottom of childform go hidden/invisible. So what would be the best solution for this sir...?

Jagadisha_Ingenious 7-Oct-13 3:27am View

@ArunRajendra : I have added the code, do let me know the correction.

Jagadisha_Ingenious 7-Oct-13 2:31am View

@ArunRajendra: As per the solution i will be able to rotate the image not the control, but i need to rotate the control itself. In windows form we cannot add image directly to the form(background image can be changed) but i have a image of 25pix which is added using either picturebox or a imagelist. Also if we try to rotate the image in the picture box it rotates & background we find original image without orientation. Any solution for this....?

Jagadisha_Ingenious 19-Sep-13 2:31am View

@Sergey Alexandrovich Kryukov: Sir i am not minimizing & restoring the form every 500ms i just did it once & found this type of flicker occurring while the communication is in process & if communication is stopped the flickering stops too.

Jagadisha_Ingenious 18-Sep-13 2:50am View

@Sergey Alexandrovich Kryukov: Sir i forgot to mention that the flickering occurs when i minimize & restore the MDI Parentform containg the childform in it, & not when i minimize & restore the childform.

@Sergy Alexandrovich Kryukov: I have a mdi form in which i have opened 1 of the childform, containing rectangle shape, serial port communication & many other controls in it. What i do is, i will select the comport & press start button to start communicating through serial port. Once the communication starts the received data is processed & UI is updated accordingly. What i feel is while updating the UI the rectangle shape is being infected. The following is my code.

To fix the rectangle shape @ the centre of the screen i have used the following code:

private void DisplayWindow_MaximumSizeChanged(object sender, EventArgs e)
{
rectangleShape1.Left = (Screen.PrimaryScreen.Bounds.Width / 2)-183;
rectangleShape2.Left = (Screen.PrimaryScreen.Bounds.Width / 2) - 153;
}

private void rectangleShape1_ParentChanged(object sender, EventArgs e)
{
rectangleShape1.Anchor = AnchorStyles.Top;
rectangleShape2.Anchor = AnchorStyles.Top;
}
Serial Port Comm part:

private void comstartbtn_Click(object sender, EventArgs e)
{
sp.PortName = cmpprtcmbbox.SelectedItem.ToString();
sp.Parity = Parity.None;
sp.StopBits = StopBits.One;
sp.BaudRate = 9600;
sp.DataBits = 8;
timer = new System.Threading.Timer(new TimerCallback(Receive_Data), null, 0, 500);

try
{
if (sp.IsOpen == false)
{
sp.Open();
comstartbtn.Enabled = false;
cmpprtcmbbox.Enabled = false;
comstpbtn.Enabled = true;
((MainWindow)this.MdiParent).toolStripStatusLabel1.Text = "STATUS : " + sp.PortName+ " Opened successfully";
}

}
catch (Exception ex)
{

}
}

private void Receive_Data(object obj)
{

try
{
int btr = sp.BytesToRead;
data_9 = new byte[btr];
sp.Read(data_9, 0, btr);

for (int i = 0; i < btr; i++)
{
if (data_9[i] == 36 && start_collction == 0)
{
start_collction = 1;
}

if (start_collction == 1)
{
serialData.Append(data_9[i].ToString() + ",");
if (serialData.ToString().Contains("65"))
{
start_collction = 0;
q = serialData.ToString().Split(',');
List<string> list = new List<string>(q);
list.Remove("65");
list.Remove("");

if (q[1] == "1")
{
UV1ledbulb.Blink(0);
}
}
}

This UV1ledbulb lies on the rectangle shape.

@z3ngew: Hi i tried but it doesn't work. I have a MDI form in which one of the child form consists of rectangle shape. This rectangle shape changes its location when i minimize & restore the MDI Parent form & not when i do the same with the child form. So how do i avoid this...?

@Syed Shabeer: Thanks for your valuable suggestion the issue got resolved, the flickering stopped but it takes time to load, so how to increase the speed of it..?

Jagadisha_Ingenious 11-Aug-13 0:47am View

@Virusstorm: Yup thats exactly what i am doing... Then when i click load button & select the saved file i need to show the values that was saved in those ComboBoxes.

Jagadisha_Ingenious 9-Aug-13 2:52am View

@virusstorm: Thanks for the suggestion u have given. But the actual stuff is i have many comboboxes to which the data is added manually. While loading the form these values are loaded with the selected index to show @ startup. I have 2 buttons save parameters & another load parameters, so during save i am fetching the selecteditem from all the comboboxes, creating a xml file and saving it in a local directory. When i click on load parameters i need to fetch & display the parameters that was saved earlier. So in this case how to do it...?

Jagadisha_Ingenious 6-Aug-13 2:59am View

@OriginalGriff: Access/Jet/Ace are good options, i want to know how much amount of data can they store in them..? What would be the limitations involved in it..? Will it slow down the process(read/write) if there are more number of data in any of the above mentioned databases.

Jagadisha_Ingenious 17-Jun-13 3:57am View

@Sergey Alexandrovich Kryukov: When i had asked this question none answered it, so when i found a solution i added it.

Jagadisha_Ingenious 11-Jun-13 5:04am View

@john-pH: Hi john thanks for replying & i have implemented the query you have posted & it works fine, but what if the device1 shows up only 3 or more faults. As per your query i will get only the top 5 data's from the database. If it has more or less than 5 how to get all those log details. Since this logging is dynamic.

Thanks in advance.

Jagadisha_Ingenious 4-Jun-13 1:59am View

@Jameel Moideen: Its a 50-50 case where comments say some are happy with SQL & others with MS Access so it doesn't make any difference. What i need is just pick the date & time of the day along with few string & save it in a database faster. I am able to write it to the database but it usually takes 1s-1.5s on an avg time to save it to the database.

Jagadisha_Ingenious 3-Jun-13 4:38am View

@Sergey Alexandrovich Kryukov: Sir thank u for the support you gave to me i was able to resolve the issue. I removed all the timers & used only threads along with few changes in the code i was able to get the expected result. Once again thanks a lot for your support.

Jagadisha_Ingenious 1-Jun-13 7:50am View

@Sergey Alexandrovich Kryukov: Sir running thread continuously isn't helping out. That flashing of button event is taking more time.

Jagadisha_Ingenious 1-Jun-13 2:32am View

@Sergey Alexandrovich Kryukov: Sir i want this polling process to happen continuously i.e, 24hrs a day & 365 days a year. So if i don't use timer, how to run the thread continuously. Its a monitoring system app that i have developed.

Jagadisha_Ingenious 1-Jun-13 1:47am View

@Sergey Alexandrovich Kryukov: Sir I wanted to do polling @ different intervals so i used a timer, is it a bad thing to do...?

@Sergey Alexandrovich Kryukov :

private void LogMessage(string slaves)
{
if (!string.IsNullOrEmpty(slaves))
{
List<string> slaveList = slaves.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries).ToList();

foreach (string slave in slaveList)
{
if (!string.IsNullOrEmpty(slave))
{
string str = "insert into ErrorLog values('" + btn[add].Text + "','" + slave + "','" + DateTime.Now.ToShortDateString() + "','" + DateTime.Now.ToShortTimeString() + "')";
DataBaseHandling(str);
}
}
}
}

This is the remaining part of the program. The problem that i face is that i am looking for 1s from the slaves & save the data in database, array & flash button based on the 1s index. This process takes more time. So do help me out & thanks in advance.

@Sergey Alexandrovich Kryukov: Sir, i am doing polling using a different thread other than UI thread, bt still it doesn't make much difference how do i improve its performance. Is there any other solution for this...?

@Sergey Alexandrovich Kryukov: Sir if polling is a bad technique, then which other method is suitable for getting the status of each device. yes i am using a single thread for doing the polling process. If timers are bad then how do i make button change its back color in every 250ms or 500ms.

@R.B. Sorry it is also SID in the third if condition too. And i don't want that way if i initialize the counter instead of forloop & do it also the same problem persists so how to eliminate it..?

Jagadisha_Ingenious 20-May-13 7:31am View

@CHill60: I want to add values to the fieldindex1[] with their respective data & start the timer only once if any of the if conditions are satisfied. If incase more than 1 if conditions are satisfied i should save for ex: fieldindex1[0] = 1; & fieldindex1[1] = 2, if 1st & 2nd if conditions are true. I don't want to use for loop here instead a better way to implement this would be good, since in the same iteration if 2 of the if conditions are satisfied i cannot save both values in the array as it will be over written, where i will loose the previous value.

Sir, I have actually hid the toolstrip menuitem so any other way to achieve this...?

Jagadisha_Ingenious 28-Mar-13 9:00am View

Dear Sir, I have implemented your code it works fine. Basically i have an array of buttons in a panel in which i wanted this enable/disable option to be included. As per the code u have given i am able to deactivate the button individually & enable it by clicking on any other button. The problem is if i deactivate all the buttons i am left with no choice to activate it. I cannot activate anyone. So how to achieve this..?

Jagadisha_Ingenious 28-Mar-13 6:40am View

Ya fine thats correct but i need the button state to be pressed with 1 click & normal with another.

Jagadisha_Ingenious 28-Mar-13 6:39am View

I am working on windows form platform.

Jagadisha_Ingenious 28-Mar-13 6:38am View

Similar to toggling stuff in a single button. Windows form platform is what i am working on...

Jagadisha_Ingenious 27-Mar-13 4:06am View

Yes sir i do agree..

Jagadisha_Ingenious 27-Mar-13 3:48am View

Yes sir i have received your mail n thanks for that. I was able to resolve the issue to some extent i guess. Like if i switch from 1 form to another 100 times i get only 5-6 times error mentioned earlier. I had to change few instructions in my code after which it is working fine.

Jagadisha_Ingenious 26-Mar-13 1:27am View

Sir your answer refers to polling of database & handling it, but i am not polling a database in the app that i have developed, i am just recording the instance when i get an error while polling for data through serial port.

Jagadisha_Ingenious 25-Mar-13 2:53am View

Sir so whats your suggestion on that issue..?

Jagadisha_Ingenious 25-Mar-13 1:21am View

Fine sir i will be waiting for it..

Jagadisha_Ingenious 25-Mar-13 1:18am View

Sure & thanks u sir..

private void timer2_Tick(object sender, EventArgs e)
{
for (int n = 0; n < btn.Length; n++)
{
if (errorIndexOne[n] == 1)
{
btnTest.BackgroundImage = global::AnnunciatorMonitoringTool.Properties.Resources.lightbulb;
string str = "insert into ErrorLog values('" + annName + "','" + btn[n].Text + "','" + DateTime.Now.ToShortDateString() + "','" + DateTime.Now.ToShortTimeString() + "')"; ;
DataBaseHandling(str);
if (btn[n].BackColor == Color.LightGreen)
{
btn[n].BackColor = Color.Red;
}
else
{
btn[n].BackColor = Color.LightGreen;
}
}

else if (errorIndexOne[n] != 1)
{
btn[n].BackColor = Color.LightGreen;
}

}

I am trying to record each flashing event of the button in the database. The UI consists of few buttons in a panel & the panel is surrounded by rectangle making it look like a border around the panel. The panel size is changeable based on the no of buttons in it.
This timer2_tick event is fired when a particular data is coming from serial port. I am looking for a particular data from serial port if get that data i fire this timer event & further process the rest.

Jagadisha_Ingenious 25-Mar-13 0:46am View

Then why does the timer stop when running? Is it because of the UI i have developed? Sometimes even the system hangs when the timer is running, why is that so...?

Sir send me ur mail Id i will forward you the entire solution.. I dont have line 462 in my Annunciator devices form.

Its is the same code from which i have started asking questions...

void Annunciator_Devices_Click(object sender, EventArgs e)
{
if (form2 == null || form2.IsDisposed)
{
form2 = new Annunciator_Window(descriptionName, btnName.Text, Port, devicescount, SlvID);
form2.MdiParent = MdiParent;
form2.WindowState = FormWindowState.Maximized;
// myPictureForm.FormClosing += form2_Closing;
this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.MainForm_FormClosing);
}
this.Hide();
form2.Show();
}

@Sergey Alexandrovich Kryukov: Sir i have used this system.threading.timer as i told u earlier, but whats happening is it runs continuously for an hour or more than that n suddenly stops. Is it due to overflow of the timer...?

Jagadisha_Ingenious 18-Mar-13 10:20am View

@Sergey Alexandrovich Kryukov: Hi, i am using system.threading.timer in my application. I have used one of them for receiving data from serial port & other timer making button change its back color continuously indicating fault as per my application. So do these timers perform as expected, run continuously?

Jagadisha_Ingenious 16-Mar-13 4:32am View

@Sergy Alexandrovich Kryukov:I am using system timer for getting & windows form timer for updating UI. Which timer among the four available can do the work as told earlier?

Jagadisha_Ingenious 13-Mar-13 4:35am View

@Bernhard Hiller:I have used system timer for data processing event & windows form timer for flashing of button..
