• PowerPoint API, how to change slide layout programmatically

  - by 112811688864492097861

  Hello, I'm working on PowerPoint Add-In and I was faced with trouble I couldn't solve myself. The point is I need to change the slide Layout programmaticaly with C# (the Add-In Express 2009 for Office and .NET is used). If the new layout is a predefined one everything is fine but I need to set a custom layout as a new one (without slide recreating). Unfortunately, I didn't find any information on how to do it, PowerPoint object model reference documentation didn't answer me as well. There is just the ability to create a new slide that uses custom layout. I've done an experiment seria and have ensured that the Slide object stayed being the same while I have been changing layout both predefined and custom ones. I don't want to create a new slide when I need just switch the layout. Is it possible at all? Please help me to find a way of doing it. Thanks in advance.

• Statistics help on 3 choices

  - by DaveSav

  I'm working on an Android app where, at one point, the user is asked to input whether something helped. Their options are 'Yes', 'No' and 'Don't Know'; or they could choose to ignore it. This is for multiple 'somethings' over a date range. A summary view for a date range shows the percentage of 'Yes', 'No' and 'Don't Know' entered for each 'something'. I'm also showing the 'Overall Effectiveness' as the percentage of 'Yes' inputs, which I realise is incorrect. I am thinking of changing that to 'Yes' minus 'No', but that doesn't address the 'Don't Know' inputs. How would I handle the data so that 'Overall Effectiveness' represents all 3 data inputs? So, for a 'something' which has a 'Yes' of 25%, a 'No' of 25% and a 'Don't Know' of 50%, would that be an 'Overall Effectiveness' of 0% ? Or would the 'Don't Know' affect that figure at all? As an additional to that, what graph type, other that Pie, would best display all 3 data?

• How to set DataGridView columns text format to uppercase by adding new property?

  - by Jooj

  Hello, I have a custom DataGridView control and want to set the text format for custom columns in the designer (CellStyle builder). Let's say I want to make the text format to uppercase. After searching about this I've found some solutions with adding new events and then changing the text format but this is not what I want. I want to add a new property to all designed columns and there set or change the text format. How to do this? Thank and best regards.

• What are the disadvantages of using a StringBuilder?

  - by stickman

  I know that StringBuilder is more efficient than a normal string when processing code which modifies the string value a lot because although strings act like value types, they are actually reference, which makes them immutable so every time we change it, we need to create a new reference in memory. My question is that, why doesn't .NET just use stringBuilder by default? There must be some disadvantages of it over just using String. Can anyone tell me what they are? The only thing I can think of is perhaps it is a heavier object and it takes more time to instantiate so if you aren't changing the string too much, this would override the benefits of StringBuilder

• How can I return to a string address and then assign it to a new string?

  - by Y_Y

  I have 1 function that I want to return the address of an assigned string to the main function and assign an new string pointer with the same address so that the new string will have the contents of the old string. For example: unknown_datatype function() { char *old = "THE STRING"; return old; } int main() { char *snew = ""; snew = function(); return 0; } *unknown_datatype means I don't know that to put there... *How can I approach this without changing anything in the main() method

• How can I lock the cursor to the inside of a window on Linux?

  - by ZorbaTHut

  I'm trying to put together a game for Linux which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Linux. Is there one? I plan to do this in pure X code, but obviously if anyone knows of a way to do this in any Linux windowing library then I can just read the source code and figure out how to duplicate it in X.

• jQuery .get()/.post() doesn't send an updated cookie

  - by Markus

  Hello, I'am doing something like this: function setCookie(name, value, expire) { var exdate = new Date(); exdate.setDate(exdate.getDate()+expire); document.cookie=name+ "=" +escape(value)+((expire==null) ? "" : ";expires="+exdate.toGMTString()); } // When I click a button // Update the cookie setCookie("test", "1"); function getContent() { // Get the data of our new URL $.get("index.php", loadContent); } function loadContent(data) { // alert the new title // the PHP script is changing title after what cookie-value you have alert($("title", data).text()) } First of all, when Iam alerting it is still the last showing up. So I guess it doesn't send the changed cookies at all.. And for some reason I don't see the request in my Live HTTP Headers window... But also, if i request the URL(without the ajax) it works just fine What am I doing wrong here? Regards Markus

• What's the most efficient way to manage large datasets with Javascript/jQuery in IE?

  - by RenderIn

  I have a search that returns JSON, which I then transform into a HTML table in Javascript. It repeatedly calls the jQuery.append() method, once for each row. I have a modern machine, and the Firefox response time is acceptable. But in IE 8 it is unbearably slow. I decided to move the transformation from data to HTML into the server-side PHP, changing the return type from JSON to HTML. Now, rather than calling the jQuery.append() time repeatedly, I call the jQuery.html() method once with the entire table. I noticed Firefox got faster, but IE got slower. These results are anecdotal and I have not done any benchmarking, but the IE performance is very disappointing. Is there something I can do to speed up the manipulation of large amounts of data in IE or is it simply a bad idea to process very much data at once with AJAX/Javascript?

• How to connect Model through Controller to View using bindings?

  - by Paperflyer

  I have an NSTextField in my view. Its value is bound to an NSNumber *number in my controller. The controller simply calls through to the model (value) to get the appropriate value. // In the controller - (NSNumber *)number { return [NSNumber numberWithFloat:[model value]]; } - (void)setNumber:(NSNumber *)aNumber { [model setValue:[aNumber floatValue]]; } This is fine, only the controller is not notified of model changes and thus, changing the value in the model does not update the NSTextField. The only other option I can think of is to have the model notify the controller and the controller manually update the view through an Outlet. But this circumvents the binding. // In the model, after value change [[NSNotificationCenter defaultCenter] postNotificationName:@"ValueChanged" object:self]; // In the controller, after being notified - (void)updateView:(NSNotification *)aNotification { [myTextField setFloatValue:[model value]]; } Is there a better, binding-aware way to implement this communication?

• WAMP + Pear installation issue

  - by Industrial

  Hi guys, I am trying to install PEAR in my WAMP-server. The go-pear.bat is running as intended, but when it comes to changing the directories, it all goes wrong. I have followed this guide: http://phphints.wordpress.com/2008/08/26/installing-pear-package-manager-on-wamp/ The 9th line of configuration, Public Web Files directory, will not change upon command and instead says Input file error, no file extension in C:\documents I am running XP SP3. Is there anyone else who had experienced this slight issue? Thanks!

• How can I convert (string) timestamp to mysql datetime on Windows 32 bit PHP?

  - by user239619

  I'm attempting to call LinkedIn's API and store Network Updates. Each update has a Unix timestamp that I'm retrieving as a string variable from the REST XML response. I want to convert the string timestamp to a mysql datetime format. The date() function accepts an integer as the second argument for time to be converted. However, I'm on Windows 32 bit PHP and the integer type for this platform is limited to 2147483647. $timestamp = '1293714626675'; // sample pulled from linkedin $timestamp = (int) $timestamp; // timestamp now equals 2147483647 $mysqlDatetime = date('Y-m-d H:i:s', $timestamp); // produces incorrect time Is there a better method of creating the mysql datetime in PHP? I realize that I can convert it upon insert into MySQL however, that would require changing other dependent code.

• ReorderListView in WPF

  - by Philipp Schmid

  I love the controls from the Bag-Of-Tricks. I am interested in modifying the ReorderListBox control to get a ReorderListView control. However, simply changing the base class from ListBox to ListView is not working. When I try to add a ReorderListView to XAML like this: <lib:ReorderListView Grid.Row="1"> <ReorderListView.View> <GridView> <GridViewColumn Header="Data1" /> </GridView> </ReorderListView.View> </lib:ReorderListView> I get an error ("The tag 'ReorderListView.View' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'.) How do I modify the ReorderListBox example to get this to work? Has anyone already succeeded in doing this?

• Using an ActiveX object from an Outlook hosted webpage - possible?

  - by Nic Wise

  I'm trying to do the following: We have an outlook plugin, written in .NET (and C++). It does various things, and is manually installed on the end users machines (usually via AD deployment or similar) We are changing our search to use a webpage-based search, but from within outlook. That part is ok, however we want to communicate from the webpage to the surrounding outlook application. We can call into outlook by exposing an ActiveX object from our plugin, however we get security warnings, even if it's signed and marked as safe for scripting. Is this even possible? Has anyone done it? Anyone have a better way of doing it? We only need to pass in a small amount of data (a message id), and only from the webpage to outlook [update]: This is the error: automation server can't create object. We can get around it a bit by turning things off in IE, but thats not a good way to do it! Thanks

• How to update (append to) an href in jquery?

  - by John Isaacks

  I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!

• finditem() doesn't find menu, stuck with NullPointerException

  - by fdansv

  I'm stuck while changing some properties on my options menu at onCreateOptionsMenu(). It seems like findItem() returns null, even though I'm pretty sure that the reference to the menu item is correct. My code looks as follows: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_profile, menu); MenuItem leftie = menu.findItem(R.id.menu_profile); leftie.setIcon(R.drawable.ic_menu_mapmode); leftie.setTitle(R.string.back_map); leftie.setIntent(authIntent); return true; } I really don't know what can be wrong there. Thanks in advance :) EDIT: I forgot to include the actual problem.

• How to define an array inside a function in C?

  - by Arunav Dev

  So in my source file I have the folowin function: void update(state* old_state, state* measurement, uint32_t size) { state new_state[size]; //some function using measurement and old_state and returning the result in newstate arm_fadd_32(measurement,old_state,newstate,size); // rest of the code } Now the compiler throws an error saying that error#28:expression must have a constant value. I think it's due to the fact that even though inside the method the size local variable is not changing the compiler is expecting a constant while defining the size. I have tried the following: int const a = size; and then tried to reinitialize it says constant value is not known. I did some research in internet and it appears that there is no easier way without using malloc, which I don't want to since I am using the code for some embedded application. Is there a way to avoid this problem without really using malloc? Thanks in advance guys!

• How can I modify the application file of an application that is currently running (on Linux)?

  - by Hach-Que

  I have an application running called AppFS. This application has an ext2 filesystem just attached to the end of the file (it's positioned so that the application binary exists in a 1MB spacing area, followed by the ext2 data). Now I've got FUSE embedded in the program and I've managed to extract the filesystem out of the application data into a temporary file so that FUSE can mount / use it. The problem I have now is writing the temporary file back into the application file. I get "Text file busy" presumably because the application has locked itself and won't let writes occur. Is there a way I can force the file to become unlocked so I can write data to it? (It's important to note that I'm not changing the application binary area - just rewriting the ext2 component.) It needs to be unlocked without requiring root permissions (unlocked by the same user who started the application).

• Money type field returns Dollar, but regional set to UK (Windows 7)

  - by Gareth

  Hi, On a Windows 7 machine with Advantage Data Architect version 9.10.0.11, money type data is returned as Dollars, instead of Pounds. Sometimes, it will suddenly switch to Pounds, without me changing any settings. Everything else returns Pounds correctly (regional settings is UK with £ as the currency symbol). Has anyone else had this problem and/or found a solution? If I run any reports using the money data type field I can't be sure that it's going to be accurate. And no, I can't change the field type and handle the currency symbol myself. Any help would be appreciated.

• Visual source safe headaches - Deleting files

  - by maxp

  I will pre-empt and say we are stuck using VSS here so changing it is not an option. Anyway, one person, 'user a' is deleting a file from their project. They then do a 'get latest' on the folder and it doesn't come back, so the user assumes they have truely deleted it from the project. We have another user, 'user b', who then looks at 'pending checkins', sourcesafe will then do a scan of all the files in 'user b's project. It then wants to 're-add' all of the files user a deleted. This has caused a huge headache for the team. Any suggestions to stop this from happening again?

• UI Design - design pattern for city/country drop down? (ASP.NET MVC)

  - by JK

  What is the best way to do a city/country dropdown pair in ASP.NET MVC? I see lots of places with country above city, but that's unnatural: in real life we write city/country. I've used city, then country, but the problem is that the user then has to go backwards after changing the country. The other problem is what do you do about cities/countries not in your list? If city/country are both drop downs, then the user cant type their own city if it is missing. But if you have a dropdown and a textbox, that makes it unwieldy (you end up with 4 controls to enter 2 pieces of data). Are there any examples websites where the city/country dropdown pair are done in a very useable and clear manner?

• How can I determine new & previous cell value on SheetChange event in Excel?

  - by Falco Foxburr

  I have some special cells in my Excel workbooks which are managed by my Excel Add-in. I want to prevent users from changing content of those cells, but I also want to know, what value users wanted to enter to those cells. On the SheetChange event I can check what users entered to my special cells, but how do I determine the PREVIOUS value in those cells and REVERT user changes? It is not a solution for me. If I lock cell in Excel, it becomes read-only - user can not even try to enter anything to this cell - Excel popups warning dialog in this case. My problem is that I want to catch what user entered to my cell, do something with this value, and then revert cell content to original value.
