  • Error in value of default parameter [Bug in Visual C++ 2008?]

    - by HellBoy
    I am facing following issue while trying to use template in my code I have some C++ code which i call from C functions. Problem is I am getting different values in the following code for statement 1 and 2. Type id : unsigned int statement 1 : 4 statement 2 : 1 C++ Code : template <typename T> void func(T* value, unsigned int len = sizeof(T)) { cout << "Type id : " << typeid(T).name() << endl; cout << "statement 1 " << sizeof(T) << endl; cout << "statement 2 " << len << endl; } template <typename T> void func1(T data) { T val = data; func(&val); } C Code : void test(void *ptr, unsigned int len) { switch(len) { case 1: func1(*(static_cast<uint32_t *>(ptr)) break; } } This happens only on windows. On Linux it works fine.

  • Passing javascript to a function

    - by AJ
    Hello, Can I pass some Javascript to a function and then execute that Javascript from within the function, e.g. test("a = 1; b = 2; test2(a,b);"); function test(js) { // execute dynamically generated JS here. } Basically I have some code that is generated on the server and I want to pass that code to a JS function which when it has finished processing it executes the code passed as a parameter. This could also be useful for the parameter of setTimeout, then the code passed could be executed in the timeout event. Can this be done?

  • Mercurial Merging only certain changesets

    - by PostMan
    Ok, so we recently converted from SVN to Mercurial. We are using TortoiseHG normally. In our one repository we have all of our projects, C++ / .NET / ASP. We have about 100 projects, all using common library projects. So it would be quite difficult task to create multiple repo's for each project. Now, we have the default branch, and let's say branchA. I'm working on BranchA and adding my uber changes to it, and I change a common library, let's say an extension method I want to commit this to branchA and default, how would I go about this? However, I don't want all my changes from branchA to be merged into default, and I don't want all the other changes from default Hopefully this is sufficient information!

  • Jquery file format

    - by sarbe
    HI. I have multiple webpages. So I have a common external js file. And I have added this js file to every page. I have multiple check boxes in every page. And I have written the click event in the external, common js file. But I wonder how the js file should be? Currently I have written like this. $(document).ready(function() { $(".chk").click(function() { alert("hi"); }); }); But whenever I click a checkbox the click event is fired twice. it should be once. I dont know where is the error, is there any error in writing the js file? please comment.

  • Explanation of NSMutableURLRequest : setHTTPMethod

    - by kkmoslehpour
    I am new to objective c programming. I am currently trying to insert data into mysql database. I have read a couple links on this and could not find the exact answer I am looking for. Here is what I am trying to do: I have my app that user inputs a name in a text field and once the press the add button, it makes a connection to my php file and my php file does the rest of the work (using POST method) and adds the name to the mysql dataase. I have seen a lot of people use NSMutableURLRequest : setHTTPMethod :POST`` in their code (in my case my php file does that and I don't haveNSMutableURLRequest` included in my code and it works perfectly fine.) My questions are: Are there any benefits of including NSMutableURLRequest in your code when you can just call your php code to take care of the POST for you? What does NSMutableURLRequest exactly do and which way is more efficient?

  • Is it possible to authenticate user manually with oauth2

    - by iixi
    I want to authenticate a user with oauth2 to access google drive. I can get the access token required when using AccountManager to retrieve an account and then get the token with: mgr.blockingGetAuthToken(account, ApiConst.DRIVE_AUTH_SCOPE, true); But I want the user to be able to authenticate by providing username and password instead of using the account added to the phone. Is this possible? EDIT So I have tried to implement the authorization in a WebView. I followed this example. I have extracted the code request parameter but the code used to retrieve the access token seems to be deprecated and not compatible with the packages used by Google Drive SDK. This is the code used to retrieve the access token in the example: AccessTokenResponse accessTokenResponse = new GoogleAuthorizationCodeGrant(new NetHttpTransport(), new JacksonFactory(), OAuth2ClientCredentials.CLIENT_ID, OAuth2ClientCredentials.CLIENT_SECRET, code, OAuth2ClientCredentials.REDIRECT_URI).execute(); Can this be done in some other way or should I just give up?

  • Java ME Runnable object takes up memory although not made an instance yet

    - by user1646684
    I am facing a strange problem with memory in Java ME. here is a part of my code: int variable=1; while (true) { if (variable==2) { display = Display.getDisplay(this); MyCanvas mc = new MyCanvas(this); // MyCanvas is a runnable object mcT = new Thread(mc); // new thread for MyCanvas mc.repaint(); display.setCurrent(mc); mcT.start(); // run thread } if (variable==1) { // Do some other stuff } } The problem is that although still the variable is set to 1, so it does not come through the if (variable==2) condition the program consumes 300kB more memory than when I delete the code after condition if (variable==2). As far as I know the code should by executed and the objects shall be created only when I set variable to value 2. But it consumes the memory also when the code after condition "if (variable==2)" is not executed. Why does this happen?

  • Problem removing a dynamic form field in jquery

    - by rshivers
    I'm trying to remove a dynamic form field by click a button. It will also subtract whatever values it had from the total amount from my calculation. This is the code: function removeFormField(id) { var id = $(id).attr("name"); $('#target1').text($("#total" + id).map(function() { var currentValue = parseFloat(document.getElementById("currentTotal").value); var newValue = parseFloat($("#total" + id).text()); var newTotal = currentValue - newValue; document.getElementById("currentTotal").value = newTotal; return newTotal; }).get().join()); $(id).remove(); } Okay, it will do the subtraction portion of the code with no problem, this issue is with the last line to remove the field. If I comment out the rest of the code it will work, but not with the rest of the code. I know this is something simple, yet I can't seem to wrap my mind around it. Can someone please help?

  • <script> Tag cannot be self closed?

    - by Joe Hopfgartner
    I had this code in my Website <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"/> <script type='text/javascript' src='/lib/player/swfobject.js'></script> swfobject was not working (not loaded). After altering the code to: <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"></script> <script type='text/javascript' src='/lib/player/swfobject.js'></script> It worked fine. The document was parsed as HTML5. I think its funny. Okay, granted a tag that is closed and a self closing tag are not the same. So i would understand if jquery couldnt load. Altough i find it rediciulous. But what i do not understand is that jquery loads but the following, correctly written tag, doesnt?

  • Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in file

    - by Jian Lin
    Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in files (pushing it)? It can be important that: 1) You never know it is in an inconsistent state, so you try for 2 hours trying to debug the code for what's wrong. 2) With all the framework code -- potentially hundreds of files -- if some files are inconsistent with the other, can't the rake db:migrate or script/generate controller cause some damage or inconsistencies to the code base?

  • iphone keyboard won't appear

    - by d_CFO
    I can click on the field, and it momentarily turns blue, but those events plus makeFirstResponder together do not cause the keyboard to show on a UITextField. Plain vanilla code follows; I include it so others can discern what is NOT there and therefore what, presumably, with solve the problem. I put in leading spaces to format this question more like code, but the parser seems to have stripped them, thus leaving left-justified code. Sorry! UITextFieldDelete, check: @interface RevenueViewController : UIViewController <UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate> { UILabel *sgmntdControlLabel; UISegmentedControl *sgmntdControl; UITableView *theTableView; } @property(nonatomic,retain) UISegmentedControl *sgmntdControl; @property(nonatomic,retain) UILabel *sgmntdControlLabel; Delegate and source, check. -(void)loadView; // code CGRect frameTable = CGRectMake(10,0,300,260); theTableView = [[UITableView alloc] initWithFrame:frameTable style:UITableViewStyleGrouped]; [theTableView setDelegate:self]; [theTableView setDataSource:self]; // code [self.view addSubview:theTableView]; [super viewDidLoad]; } Insert UITextField to cell, check. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSInteger sectionNmbr = [indexPath section]; NSInteger rowNmbr = [indexPath row]; NSLog(@"cellForRowAtIndexPath=%d, %d",sectionNmbr,rowNmbr); static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. switch (sectionNmbr) { case 0: if (rowNmbr == 0) { cell.tag = 1; cell.textLabel.text = @"Label for sctn 0, row 0"; UITextField *tf = [[UITextField alloc] init]; tf.keyboardType = UIKeyboardTypeNumberPad; tf.returnKeyType = UIReturnKeyDone; tf.delegate = self; [cell.contentView addSubview:tf]; } if (rowNmbr == 1) { cell.tag = 2; cell.textLabel.text = @"Label for sctn 0, row 1"; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; } break; } } Successfully end up where we want to be (?), no check, (and no keyboard!): - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"didSelectRowAtIndexPath"); switch (indexPath.section) { case 0: NSLog(@" section=0, rowNmbr=%d",indexPath.row); switch (indexPath.row) { case 0: UITableViewCell *cellSelected = [tableView cellForRowAtIndexPath: indexPath]; UITextField *textField = [[cellSelected.contentView subviews] objectAtIndex: 0]; [ textField setEnabled: YES ]; [textField becomeFirstResponder]; // here is where keyboard will appear? [tableView deselectRowAtIndexPath: indexPath animated: NO]; break; case 1: // code break; default: break; } break; case 1: // code break; default: // handle otherwise un-handled exception break; } } Thank you for your insights!

  • Can I use "Stop" as subroutine name in VB?

    - by Kratz
    I'd like to create an object... say a "Movie" object. The object should have a method name "Stop", so I can have this code below dim Mov as new Movie Mov.Stop ' To execute the Stop method. In my Movie class, I should have something like this. Sub Stop() 'code here needed for the Stop subroutine End Sub However, I can't use "Stop" as name as this is a reserved word. I see a VB code that has "Stop" as one of the method. Unfortunately, the code is protected so I can't view it. How can I name a subroutine as "Stop"?

    - by Aidin
    Hi, I have a JS file that is dependent to another Js file. this Js file is something like this (Common.js) //Some codes here window.onload = PageLoad; //some codes here and then I implement PageLoad function in another Js file. ( I do this because every page has its own PageLoad implementation) and I Load these files like this on my Main.aspx : `<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">` `<\script language="javascript" type="text/javascript" src="PagesJS/pgeMain.js"></script>` `<\script language="javascript" type="text/javascript" src="JS/Common.js"></script>` ... ... `</asp:Content>` Every thing works fine on local but when I deploy it, sometimes I get PageLoad undefined Error! Can any one tells me what is wrong with this? Thanks. Aidin

  • Parse error after upgrading to PHP 5.3

    - by poer
    I have a php code that works well in PHP 5.2 but throwing "Parse error: syntax error, unexpected '}'" after upgrading to PHP 5.3. When I use echo/print or heredocs to print all the HTML part of the code, the error is gone. My question is, why this error occurred? Is this mean that in PHP 5.3 we are no longer allowed to put HTML code inside PHP code? This is my php code: function pk_stt2_admin_print_delete_form(){ global $wpdb; if ( isset($_POST['delete_terms']) && !empty($_POST['delete_terms']) ){ $msg = 'Search terms'; $success = pk_stt2_db_delete_searchterms( $_POST['delete_terms'] ); } elseif ( isset($_POST['delete_all']) ){ $msg = 'All search terms'; $success = pk_stt2_db_delete_searchterms( 'delete_all_terms' ); } else { ?> <div id="message" class="updated fade"> <p> Please enter the search terms to be deleted, separate them with a comma. </p> </div> <?php } if ( $success ){ ?> <div id="message" class="updated fade"> <p> <?php echo $msg; ?> have been deleted, <?php echo $success; ?> rows effected. </p> </div> <?php } else { ?> <div id="message" class="updated fade"> <p> Failed to delete search terms. </p> </div> <?php } } Thanks.

Example: OPEN emp_cv FOR sql_stmt; LOOP FETCH emp_cv INTO v_rcod,v_rname,v_level; EXIT WHEN emp_cv%NOTFOUND; /*here lies the code for getting v_next_level*/ if v_next_level > v_level then /*code here*/ elsif v_next_level < v_level then /*code here*/ else /*code here*/ end if; END LOOP; CLOSE emp_cv;

  • How can I update a column in a table with the result of a select statement that uses row being updat

    - by Sailing Judo
    This SQL statement example is very close to what I think I need... update table1 set value1 = x.value1 from (select value1, code from table2 where code = something) as x However, what I need to do is change the "something" in the above example to a value from the row that is being updated. For example, I tried this but it didn't work: update table1 A set value1 = x.value1 from (select value1, code from table2 where code = A.something) as x This is a one time operation to update an existing table and I'm not really looking for high performance way to do this. Any solution that gets the task done is good enough.
