  • Writing string, numeric data to Excel via C# works, but Excel does not treat numeric data correctly

    - by Chapax
    Hi, I'm getting result sets from Sybase that I return to a C# client. I use the below function to write the result set data to Excel: ***private static void WriteData(Excel.Worksheet worksheet, string cellRef, ref string[,] data) { Excel.Range range = worksheet.get_Range(cellRef, Missing.Value); if (data.GetLength(0) != 0) { range = range.get_Resize(data.GetLength(0), data.GetLength(1)); range.set_Value(Missing.Value, data); } }* The data gets written correctly. The issue is that since I'm using string array to write data (which is a mixture of strings and floats), Excel highlights every cell that contains numeric data with the message "Number Stored as Text". How do I get rid of this issue? Many thanks, Chapax

  • No exit option if something is running

    - by max
    How can I catch something going on if the user chooses the exit option from a menu? I mean I'd like to be able to manage the event of a user who is going to close the application but some activity is being performed so he/she shouldn't be able to exit. Here's the code I wrote. In a nutshell : recording is being performed -- user clicks exit -- WARNING "Process is running you can't do it"(The process goes on) nothing is running -- user clicks exit -- application closes Is it possible to solve the problem by just adding a few lines of code without having to rewrite the entire program? thanks very much in advance. MAX exitAction = new AbstractAction("Exit") { public void actionPerformed(ActionEvent e) { System.exit(0); } }; exitAction.putValue(Action.NAME, "Exit"); // description exitAction.putValue(Action.SHORT_DESCRIPTION, "Exit application");

    - by Reinhard
    to show a modal uiview out of my mainView I use: [self presentModalViewController:myController animated:YES]; and in MyController I close that view with: [self dismissModalViewControllerAnimated:YES]; But how can I know in the mainView that the modal was finished (to redraw my table)?

  • Problem with default member functions of class in C++ (constructor, destructor, operator=, copy cons

    - by Narek
    We know that compiler generates some member functions for user-defined class if that member functions are not defined but used, isn't it. So I have this kind of code: class AA { }; void main() { AA a; AA b(a); a = b; } This code works fine. I mean no compiler error. But the following code.... class AA { int member1; int member2; }; But this code gives an run time error, because variable "a" is used without being iniltialized!!! So my question is this: when we instantiate an int, it has a value. So why the default constructer doesn't work and by using those two int numbers initializes variable "a"??

  • The glutKeyboardFunc does not react to key presses immediately

    - by Nibirue
    I have a function glutKeyboardFunc(keyboard), where keyboard has: void keyboard(unsigned char key, int x, int y){ float alpha = 1.0; switch(key){ case 'c': glClearColor(1,0,0,alpha); printf("success"); break; } } This is a summary of the function; it works properly, but only once some other action has occurred. For instance, the printf statement reports success immediately on keystroke 'c', but the background color does not become active until I click somewhere else on the canvas. I want all keystrokes to have an immediate effect.

  • Do I really have to call Focus in OnMouseDown of my custom Control?

    - by Thomas
    I'm implementing a custom control that inherits from Control. I want it to be focusable (it's a kind of list box). In the constructor, I do SetStyle(ControlStyles.Selectable, true); I can now use Tab to navigate to the control. However, when the control receives a mouse click, it does not automatically claim focus. I can work around this, of course: protected override void OnMouseDown(MouseEventArgs e) { Focus(); base.OnMouseDown(e); } But this feels like a kludge that should not be necessary. Is this really the way to go? Or is there some way to tell Control to claim focus automatically when it receives a mouse click?

  • android thread management onPause

    - by Kwan Cheng
    I have a class that extends the Thread class and has its run method implemented as so. public void run(){ while(!terminate){ if(paused){ Thread.yield(); }else{ accummulator++; } } } This thread is spawned from the onCreate method. When my UI is hidden (when the Home key is pressed) my onPause method will set the paused flag to true and yield the tread. However in the DDMS I still see the uTime of the thread accumulate and its state as "running". So my question is. What is the proper way to stop the thread so that it does not use up CPU time?

  • Flash: How to get a list to be processed synchronous instead of asynchronous?

    - by Quandary
    Question: In Flash I have the below function. Now the problem is SaveFurniture, SavePolygons and SaveComments all save to the same XML file. Now SaveFurniture sends JSON encoded data to a ashx handler, which saves it in the xml on the server. The problem is, because flash sends the data asynchronous, the polygons get sent to the polygonsave ashx handler, but before saving of the furniture has completed, thus access error, write process already in progress... // cSaveData.SaveData(); public static function SaveData():void { trace("cSaveData.SaveData"); //NotifyASPXofNewScale(cGlobals.nPlanScale); SaveFurniture(); SavePolygons(); SaveComments(); } What's the best way to process this list, ONE AFTER ANOTHER ? Making a callback in all of them does make the program flow structure very confusing...

  • ImageView Force closes my application

    - by BlueFireLady
    Hi there I am really a beginner, and I have been fighting with this problem for 3 days. :( I am able to get an image to show using a grid view and an adapter as in the grid view tutorial, but I wanted to be able to just use ImageView in the xml. public class HelloImage extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView gridview = (ImageView) findViewById(R.id.gridview); gridview.setLayoutParams(new GridView.LayoutParams(85, 85)); gridview.setScaleType(ImageView.ScaleType.CENTER_CROP); gridview.setPadding(8, 8, 8, 8); gridview.setImageResource(R.drawable.hand_tool); } } When I run this it causes the app to force close when loading.

  • JAVA-SQL- Data Migration - ResultSets comparing Failing JUnit test

    - by user1865053
    I CANNOT get this JUnit Test to pass for the life of me. Can somebody point out where this has gone wrong. I am doing a data migration(MSSQL SERVER 2005), but I have the sourceDBUrl and the targetDCUrl the same URL so to narrow it down to syntax errors. So that is what I have, a syntax error. I am comparing the results of a table for the query SELECT programmeapproval, resourceapproval FROM tr_timesheet WHERE timesheetid = ? and the test always fails, but passes for other junit tests I have developed. I created 3 diffemt resultSetsEqual methods and none work. Yet, some other JUnit tests I have developed have PASSED. THE QUERY: SELECT timesheetid, programmeapproval, resourceapproval FROM tr_timesheet Returns three columns timesheetid (PK,int, not null) (populated with a range of numbers 2240 - 2282) programmeapproval (smallint,not null) (populated with the number 1 in every field) resourceapproval (smallint, not null) (populated with a number 1 in every field) When I run the query that is embedded in the code it only returns one row with the programmeapproval and resourceapproval columns and both field populated with the number 1. I have all jdbc drivers correctly installed and tested for connectivity. The JUnit Test is failing at this point according to the IDE. assertTrue(helper.resultSetsEqual2(sourceVal,targetVal)); This is the code: /*THIS IS A JUNIT CLASS****? package a7.unittests.dao; import static org.junit.Assert.assertTrue; import java.sql.Connection; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.Types; import org.junit.Test; import artemispm.tritonalerts.TimesheetAlert; public class UnitTestTimesheetAlert { @Test public void testQUERY_CHECKALERT() throws Exception{ UnitTestHelper helper = new UnitTestHelper(); Connection con = helper.getConnection(helper.sourceDBUrl); Connection conTarget = helper.getConnection(helper.targetDBUrl); PreparedStatement stmt = con.prepareStatement("select programmeapproval, resourceapproval from tr_timesheet where timesheetid = ?"); stmt.setInt(1, 2240); ResultSet sourceVal = stmt.executeQuery(); stmt = conTarget.prepareStatement("select programmeapproval, resourceapproval from tr_timesheet where timesheetid = ?"); stmt.setInt(1,2240); ResultSet targetVal = stmt.executeQuery(); assertTrue(helper.resultSetsEqual2(sourceVal,targetVal)); }} /*END**/ /*THIS IS A REGULAR CLASS**/ package a7.unittests.dao; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.ResultSetMetaData; import java.sql.SQLException; public class UnitTestHelper { static String sourceDBUrl = "jdbc:sqlserver://127.0.0.1:1433;databaseName=a7itm;user=a7user;password=a7user"; static String targetDBUrl = "jdbc:sqlserver://127.0.0.1:1433;databaseName=a7itm;user=a7user;password=a7user"; public Connection getConnection(String url)throws Exception{ return DriverManager.getConnection(url); } public boolean resultSetsEqual3 (ResultSet rs1, ResultSet rs2) throws SQLException { int col = 1; //ResultSetMetaData metadata = rs1.getMetaData(); //int count = metadata.getColumnCount(); while (rs1.next() && rs2.next()) { final Object res1 = rs1.getObject(col); final Object res2 = rs2.getObject(col); // Check values if (!res1.equals(res2)) { throw new RuntimeException(String.format("%s and %s aren't equal at common position %d", res1, res2, col)); } // rs1 and rs2 must reach last row in the same iteration if ((rs1.isLast() != rs2.isLast())) { throw new RuntimeException("The two ResultSets contains different number of columns!"); } } return true; } public boolean resultSetsEqual (ResultSet source, ResultSet target) throws SQLException{ while(source.next()) { target.next(); ResultSetMetaData metadata = source.getMetaData(); int count = metadata.getColumnCount(); for (int i =1; i<=count; i++) { if(source.getObject(i) != target.getObject(i)) { return false; } } } return true; } public boolean resultSetsEqual2 (ResultSet source, ResultSet target) throws SQLException{ while(source.next()) { target.next(); ResultSetMetaData metadata = source.getMetaData(); int count = metadata.getColumnCount(); for (int i =1; i<=count; i++) { if(source.getObject(i).equals(target.getObject(i))) { return false; } } } return true; } } /END***/ /*PASTED NEW CLASS - THIS IS A JUNIT TEST CLASS*/ package a7.unittests.dao; import static org.junit.Assert.*; import java.sql.Connection; import java.sql.DriverManager; import org.junit.Test; public class TestDatabaseConnection { @Test public void testConnection() throws Exception{ UnitTestHelper helper = new UnitTestHelper(); Connection con = helper.getConnection(helper.sourceDBUrl); Connection conTarget = helper.getConnection(helper.targetDBUrl); assertTrue(con != null && conTarget != null); } } /**END***/

  • const ready only local copies

    - by robUK
    Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a ready-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on ready-only local copies, as it confirms to anyone reading my code that it is a ready-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

  • Problem with passing folder path string to web service function via jQuery.ajax

    - by the_V
    Hello, I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file): var d = "{'str':'<%=System.DateTime.Now.ToString() %>', 'applicationPath':'<%=GetApplicationPath() %>'}"; $.ajax({ type: "POST", url: "http://localhost/testwebsite/TestWebService.asmx/Test", data: d, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status, error) { var err = eval("(" + xhr.responseText + ")"); alert(err.Message); }, success: function (msg) { } }); That's what GetApplicationPath method looks like: protected string GetApplicationPath() { return HttpUtility.HtmlEncode(Request.PhysicalApplicationPath); } And here is a header of web-service function which I'm trying to call: public void Test(string str, string applicationPath) Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:\Projects\Samples\mytestwebsite\'". How can I overcome this?

  • Controling the visibility of a Bitmap in .NET

    - by ET
    Hi everyone, I am trying to create this simple application in c#: when the user double clicks on specific location in the form, a little circle will be drawn. By one click, if the current location is marked by a circle - the circle will be removed. I am trying to do this by simply register the MouseDoubleClick and MouseClick events, and to draw the circle from a .bmp file the following way: private void MouseDoubleClick (object sender, MouseEventArgs e) { Graphics g = this.CreateGraphics(); Bitmap myImage = (Bitmap)Bitmap.FromFile("Circle.bmp"); g.DrawImage(myImage, e.X, e.Y); } My problem is that I dont know how to make the circle unvisible when the user clicks its location: I know how to check if the selected location contains a circle (by managing a list of all the locations containig circles...), but I dont know how exactly to delete it. Another question: should I call the method this.CreateGraphics() everytime the user double-clicks a location, as I wrote in my code snippet, or should I call it once on initialization?
