  • Bypass using Alter Access Mappings for to Open Web from SPItemEventProperties

    - by Greg Ogle
    In the following code, // class overrides SPItemEventreceiver public override void ItemAdding(SPItemEventProperties properties) { using (var site = new SPSite(properties.SiteId)) //SiteId is integer { ... } } The following exception is thrown: System.IO.FileNotFoundException: The Web application at http://URL could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application. One way to work around this is to hard-code (or configure) the URL specified in Alternate Access Mappings. Putting the correct URL in Alternate Access Mappings is ultimately the correct solution, but if possible, I need a work-around that doesn't require configuration.

  • For Qt 4.6.x, how to auto-size text to fit in a specified width?

    - by darenchow
    Inside of my QGraphicsRectItem::paint(), I am trying to draw the name of the item within its rect(). However, for each of the different items, they can be of variable width and similarly names can be of variable length. Currently I am starting with a maximum font size, checking if it fits and decrementing it until I find a font size that fits. So far, I haven't been able to find a quick and easy way to do this. Is there a better, or more efficient way to do this? Thanks! void checkFontSize(QPainter *painter, const QString& name) { // check the font size - need a better algorithm... this could take awhile while (painter->fontMetrics().width(name) > rect().width()) { int newsize = painter->font().pointSize() - 1; painter->setFont(QFont(painter->font().family(), newsize)); } }

  • snprintf and Visual Studio 2010

    - by Andrew
    I'm unfortunate enough to be stuck using VS 2010 for a project, and noticed the following code still doesn't build using the non-standards compliant compiler: #include <stdio.h> #include <stdlib.h> int main (void) { char buffer[512]; snprintf(buffer, sizeof(buffer), "SomeString"); return 0; } (fails compilation with the error: C3861: 'snprintf': identifier not found) I remember this being the case way back with VS 2005 and am shocked to see it still hasn't been fixed. Does any one know if Microsoft has any plans to move their standard C libraries into the year 2010?

  • How to use NSArray of NSArray object in objective c?

    - by user1306926
    I declared a NSArray object in .h file as @property (nonatomic, assign) NSArray *scnArray; and in .h file under - (void)viewDidLoad I created three different NSArray objects as NSArray *obj1 = [[NSArray alloc] initWithObjects:@"1",@"0",@"0",nil]; NSArray *obj2 = [[NSArray alloc] initWithObjects:@"0",@"3",@"0",nil]; NSArray *obj3 = [[NSArray alloc] initWithObjects:@"0",@"0",@"5",nil]; scnArray = [[NSArray alloc] initWithArray:obj1]; [scnArray arrayByAddingObjectsFromArray:obj2]; [scnArray arrayByAddingObjectsFromArray:obj3]; and if I access this scnArray from any other function NSArray *caseArray = [scnArray objectAtIndex:index];//index will be 0, 1, 2... I am getting BAD_ACCESS_ERROR. What is the problem here and how can I correct to use it?

  • Concatenating NSString inside of UITextView

    - by Jason
    I'm some trouble adding strings together for a UITextView in my app. The method I've been using is this (header) #import <UIKit/UIKit.h> @interface calculatorViewController : UIViewController { IBOutlet UITextView *output; } -(IBAction)b1; @property(nonatomic, copy) NSString *output; @end (main) #import "calculatorViewController.h" @implementation calculatorViewController -(void)b1 { [output stringByAppendingString:@"hi"]; } The problem I've been having with this method is when I use the button the app crashes. The warning it gives me is 'UITextView' may not respond to '-stringByAppendingString:' When I replace output with at string it works though and that confused me. Any suggestions? Am I doing something wrong? Thanks

  • any way to get sharepoint groups with a given site url

    - by standley-nguyen
    Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

  • How to pop Toolwindow in a defined position

    - by Enmanuel
    Hi everyone. Im trying to integrate a toolwindow in a Winforms application, it will be a tiny floating window to display element details in a listbox. What I need is pop the window in a relative position to the control that triggers the action, so here is the thing: the Location property gives me the relative position of the control from its container (the main form in this case) so this is the workaround im using: public void Show(kTextBox source) { Point absCoord = source.PointToScreen(source.Location); this.Location = this.PointToClient(absCoord); base.Show(); } Basically this is: get the absolute control position and set this position (previously converted into owner relative) to the toolwindow. I think it should work just fine but is missing for a certain degree, and it varies depending what control i use. Its kinda confusing. Been there anyone?? Thanks in advance.

  • How to highlight text automatically inside an UIAlertView text field

    - by user333624
    Hello everyone I have an UIAlertView with a textfield that shows a default value and two buttons, one to cancel and the other one to confirm. What I am trying to do is that when the alert view is popped up the default value is highlighted so the user can override the whole value faster than manually erasing it. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Title" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Continue",nil]; [alerta addTextFieldWithValue:@"87893" label:@"value"]; UITextField *textField = [alert textField]; campoTexto.highlighted = YES; campoTexto.keyboardType = UIKeyboardTypeNumbersAndPunctuation; [alertt show]; [alert release]; } for some reason there is a highlighted attribute for the textfield but it doesn't seem to work and there is no trail of that attribute in the Class documentation.

  • java - how to split string in to multiple parts?

    - by Ewen
    I have a string that contains a value "firstword second third", and an ArrayList. I want to split the whole string in to by spaces and add the splitted strings in to the ArrayList. For example,"firstword second third" can be split to three separate strings and added three times in to the ArrayList. "1 2 3 4" can be splitted in to 4 strings and added 4 times in to the ArrayList. See the code below: public void separateAndAdd(String notseparated) { for(int i=0;i<canBeSepartedinto(notseparated);i++{ //what should i put here in order to split the string via spaces? thearray.add(separatedstring); } } public int canBeSeparatedinto(String string) //what do i put here to find out the amount of spaces inside the string? return .... } Please leave a comment if you dont get what I mean or I should fix some errors in this post. Thanks for your time!

  • iPhone CGContext: drawing two lines with two different colors

    - by phonecoddy
    I am having some troubles using the CGContext with an iPhone app. I am trying to draw several lines with different colors, but all the lines always end up having to color, which was used last. I tried several approaches I could think of, but haven't been lucky. I set up a small sample project to deal with that issue. This is my code, I use in the drawRect method. I am trying to draw a red and a blue line: - (void)drawRect:(CGRect)rect{ NSLog(@"drawrect!"); CGContextRef bluecontext = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(bluecontext, 2.0); CGContextSetStrokeColorWithColor(bluecontext, [UIColor blueColor].CGColor); CGContextMoveToPoint(bluecontext, 1, 1); CGContextAddLineToPoint(bluecontext, 100, 100); CGContextSetStrokeColorWithColor(bluecontext, [UIColor redColor].CGColor); CGContextAddLineToPoint(bluecontext, 200, 100); CGContextStrokePath(bluecontext); } thanks for your help

    I want to bind a custom property of a windows form to a second property, so when I update the former the latter gets the same value.

  • Hiding/Unhiding Control in Gridview’s column - shifting problem

    - by lupital
    This is a follow up to my previous question: link text In gridview's column i have a linkbutton and a label under it. I want to hide/unhide label when linkbutton is clicked. I use javascript because i don't want any postbacks. The code: protected void gvwComments_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { LinkButton lButton = ((LinkButton)e.Row.Cells[2].FindControl("lbtnExpand")); Label label = ((Label)e.Row.Cells[2].FindControl("lblBody")); lButton.Attributes.Add("onclick", string.Format("HideLabel('{0}'); return false;", label.ClientID)); } } function HideLabel(button) { var rowObj = document.getElementById(button); if (rowObj.style.display == "none") { rowObj.style.display = "block"; } else { rowObj.style.display = "none"; } } The problem is that when I unhide the label by clicking on button, linkbutton is shifted a a bit upper it's original position in the cell. Is it possible to preserve linkbutton's position in the gridviews cell?

    Hi, I'm reflecting a property 'Blah' its Type is ICollection public ICollection<string> Blah { get; set; } private void button1_Click(object sender, RoutedEventArgs e) { var pi = GetType().GetProperty("Blah"); MessageBox.Show(pi.PropertyType.ToString()); } This gives me (as you'd expect!) ICollection<string> ... But really I want to get the collection type i.e. ICollection (rather than ICollection<string>) - does anyone know how i'd do this please?

  • Efficient way to delete a line from a text file (C#)

    - by Valentin Vasilyev
    Hello. I need to delete a certain line from a text file. What is the most efficient way of doing this? File can be potentially large(over million records). Thank you. UPDATE: below is the code I'm currently using, but I'm not sure if it is good. internal void DeleteMarkedEntries() { string tempPath=Path.GetTempFileName(); using (var reader = new StreamReader(logPath)) { using (var writer = new StreamWriter(File.OpenWrite(tempPath))) { int counter = 0; while (!reader.EndOfStream) { if (!_deletedLines.Contains(counter)) { writer.WriteLine(reader.ReadLine()); } ++counter; } } } if (File.Exists(tempPath)) { File.Delete(logPath); File.Move(tempPath, logPath); } }
