  • Why can't I set the Image Source in WPF app?

    - by elmonty
    I'm just learning WPF. I'm using VS 2008. I've added an Image control to my XAML, and I added a GIF file to the project. If I use the XAML Designer's property panel to set the image's Source property, the drop-down list for the Source property contains the following: C:\Sample Project;component/pinHorizontal.gif There are several problems with this: My project, named "Sample Project," is not in the root of my drive. Why is ";component" in there? If I select this value as given, I get the error "Property value is not valid" (yeah, no kidding). If I go into the XAML source and set the Source property manually, like so: The XAML Designer gives me this error: "The file pinHorizontal.gif is not part of the project or its 'Build Action' property is not set to 'Resource'." Why is this task so difficult? How do I assign an image source?

  • Getting a Method's Return Value in the VS Debugger

    - by Bullines
    Is it possible to get a method's return value in the Visual Studio debugger, even if that value isn't assigned to a local variable? For example, I'm debugging the following code: public string Foo(int valueIn) { if (valueIn > 100) return Proxy.Bar(valueIn); else return "Not enough"; } Since I'm not setting any local variables in Foo, and assuming I'm not setting a break point in whatever's calling Foo, is there a way to see what the return value is if I have a breakpoint inside of Foo (or another way)? I don't have much experience with the Autos or Intermediate windows, so I'm not sure if those are even a valid option or not.

  • Problem with custom Dialog Android

    - by Nanis
    Hi, I have a custom Dialog on my app and I have a problem to do what I would like. I explain. My Dialog have had 4 Buttons. (Back, Valid, Modify and Restore) When user click on Modify or Valid I would like to call another activity. So I use Intent but it crash.

  • How can I use htaccess to protect a subdirectory of codeigniter installation?

    - by Art Peterson
    I have codeigniter installed at the root directory, and would like to have a subdirectory called "test" password protected using htaccess. I keep getting a "404 page not found" no matter what I try. The directory structure is: /public_html /css /images /system (codeigniter directory) /test .htaccess .htaccess .htpasswd index.php The root .htaccess file looks like: RewriteEngine On RewriteBase / Options -Indexes # Removes trailing slashes RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.+)/$ $1 [L,R=301] # Enforce www RewriteCond %{HTTP_HOST} !^(www) [NC] RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301] #Checks to see if the user is attempting to access a valid file, #such as an image or css document, if this isn't true it sends the #request to index.php RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !^(.*)test(.*) RewriteRule ^(.*)$ index.php?/$1 [L] The /test/.htaccess file: AuthUserFile /home/dir/.htpasswd AuthName "Protected Area" AuthType Basic <limit GET POST PUT> require user adminuser </limit> I'm not even getting the authentication prompt, just the codeigniter 404 page when I navigate to the url "http://www.mydomain.com/test/". Please advise!

  • How to paint background of specific range of text in NSTextView

    - by Rui Pacheco
    Hi, This is not a specific bug, its more about not knowing how to do something. I've an NSTextView and I need to paint the background of specific ranges of text when the user clicks on a specific part of the text view. I've tried this but I just get erratic behaviour in the sense that sometimes text loses the foreground color or the background doesn't span the whole range: NSLayoutManager *layoutManager = [myTextView layoutManager]; [layoutManager removeTemporaryAttribute:NSBackgroundColorAttributeName forCharacterRange:range]; [[myTextView layoutManager] setTemporaryAttributes:attributes forCharacterRange:range]; For the sake of simplicity assume that range is always a valid string (it is in my testing environment).

    I have a text like: [lang_de]Content in German[/lang_de][lang_en]Content in English[/lang_en]. I want to replace all text between [lang_en] and [/lang_en] including the opening and closing language tag. This is my current regex: UPDATE wp_posts SET post_content = '" . addslashes(preg_replace("/[lang_en](.*)[\/lang_en]/", '', $row['post_content'])) .

  • Representing robot's elbow angle in 3-D

    - by Onkar Deshpande
    I am given coordinates of two points in 3-D viz. shoulder point and object point(to which I am supposed to reach). I am also given the length from my shoulder-to-elbow arm and the length of my forearm. I am trying to solve for the unknown position(the position of the joint elbow). I am using cosine rule to find out the elbow angle. Here is my code - #include <stdio.h> #include <math.h> #include <stdlib.h> struct point { double x, y, z; }; struct angles { double clock_wise; double counter_clock_wise; }; double max(double a, double b) { return (a > b) ? a : b; } /* * Check if the combination can make a triangle by considering the fact that sum * of any two sides of a triangle is greater than the remaining side. The * overlapping condition of links is handled separately in main(). */ int valid_triangle(struct point p0, double l0, struct point p1, double l1) { double dist = sqrt(pow((fabs(p1.z - p0.z)), 2) + pow((fabs(p1.y - p0.y)), 2) + pow((fabs(p1.x - p0.x)), 2)); if((max(dist, l0) == dist) && max(dist, l1) == dist) { return (dist < (l0 + l1)); } else if((max(dist, l0) == l0) && (max(l0, l1) == l0)) { return (l0 < (dist + l1)); } else { return (l1 < (dist + l0)); } } /* * Cosine rule is used to find the elbow angle. Positive value indicates a * counter clockwise angle while negative value indicates a clockwise angle. * Since this problem has at max 2 solutions for any given position of P0 and * P1, I am returning a structure of angles which can be used to consider angles * from both direction viz. clockwise-negative and counter-clockwise-positive */ void return_config(struct point p0, double l0, struct point p1, double l1, struct angles *a) { double dist = sqrt(pow((fabs(p1.z - p0.z)), 2) + pow((fabs(p1.y - p0.y)), 2) + pow((fabs(p1.x - p0.x)), 2)); double degrees = (double) acos((l0 * l0 + l1 * l1 - dist * dist) / (2 * l0 * l1)) * (180.0f / 3.1415f); a->clock_wise = -degrees; a->counter_clock_wise = degrees; } int main() { struct point p0, p1; struct angles a; p0.x = 15, p0.y = 4, p0.z = 0; p1.x = 20, p1.y = 4, p1.z = 0; double l0 = 5, l1 = 8; if(valid_triangle(p0, l0, p1, l1)) { printf("Three lengths can make a valid configuration \n"); return_config(p0, l0, p1, l1, &a); printf("Angle of the elbow point (clockwise) = %lf, (counter clockwise) = %lf \n", a.clock_wise, a.counter_clock_wise); } else { double dist = sqrt(pow((fabs(p1.z - p0.z)), 2) + pow((fabs(p1.y - p0.y)), 2) + pow((fabs(p1.x - p0.x)), 2)); if((dist <= (l0 + l1)) && (dist > l0)) { a.clock_wise = -180.0f; a.counter_clock_wise = 180.0f; printf("Angle of the elbow point (clockwise) = %lf, (counter clockwise) = %lf \n", a.clock_wise, a.counter_clock_wise); } else if((dist <= fabs(l0 - l1)) && (dist < l0)){ a.clock_wise = -0.0f; a.counter_clock_wise = 0.0f; printf("Angle of the elbow point (clockwise) = %lf, (counter clockwise) = %lf \n", a.clock_wise, a.counter_clock_wise); } else printf("Given combination cannot make a valid configuration\n"); } return 0; } However, this solution makes sense only in 2-D. Because clockwise and counter-clockwise are meaningless without an axis and direction of rotation. Returning only an angle is technically correct but it leaves a lot of work for the client of this function to use the result in meaningful way. How can I make the changes to get the axis and direction of rotation ? Also, I want to know how many possible solution could be there for this problem. Please let me know your thoughts ! Any help is highly appreciated ...

  • Memory Issues When DOM Parsing A Large XML File on Android Devices

    - by tonyc
    Hey awesome SO users, I have an Android application that parses an XML file for users and displays results in a much more mobile friendly format. The app works great for most users, but some users have lots and lots of data and the app crashes on them because it runs out of memory. Is there any way I have a DOM style XML parser quit parsing data after a certain amount of parsing? I only need the first 30 or so elements so it would make the application much more efficient. I'd like to use a SAX or pull parser instead, but the XML I'm parsing is not valid and I have no control over it. Unless anyone has some good SAX solutions that let me parse messy, invalid XML, I think DOM is the only way to go. Thanks for reading!

  • Generate 10-digit number using a phone keypad

    - by srikfreak
    Given a phone keypad as shown below: 1 2 3 4 5 6 7 8 9 0 How many different 10-digit numbers can be formed starting from 1? The constraint is that the movement from 1 digit to the next is similar to the movement of the Knight in a chess game. For eg. if we are at 1 then the next digit can be either 6 or 8 if we are at 6 then the next digit can be 1, 7 or 0. Repetition of digits are allowed - 1616161616 is a valid number. Is there a polynomial time algorithm which solves this problem? The problem requires us to just give the count of 10-digit numbers and not necessarily list the numbers.

  • Reporting Services SQL Server 2005 File Share Error

No matter the permissions or accounts used by reporting services it always comes back with "A logon error occurred when attempting to access the file share. The user account or password is not valid." Since this is saving reports over the network and both admin accounts and open network/file permissions to everyone were both tried so I'm left wondering if this is an issue with Reporting Services 2005 has troubles with Windows 7 over the network.

  • How do I change a Git remote HEAD to point to something besides "master"

    - by jhs
    Short version: How do I set a Git remote's HEAD ref to point to something besides "master"? My project has a policy not to use a "master" branch (all branches are to have meaningful names). Furthermore, the canonical master repository is only accessible via ssh://, with no shell access (like GitHub or Unfuddle). My problem is that the remote repository still has a HEAD reference to refs/heads/master, but I need it to point to a different branch. This is causing two problems: When cloning the repo, there this, warning: remote HEAD refers to nonexistent ref, unable to checkout. That's confusing and inconvenient. The web-based code browser depends on HEAD as a basis for browsing the tree. I need HEAD to point to a valid branch, then.

  • How do i sign variables?

    - by acidzombie24
    I have a few variables that must be stored on the client side. As usual anything on client side can be tampered. I would like to sign a few variables and verified them when the data is sent back to the server. At the moment i think they are 5 64bit vars. On the server i would like to sign those 5 variables, then ensure the signature is valid when the client sends it back. How do i do this using C# .NET?

  • Make NSFormatter validate NSTextFieldCell continuously

    - by harms
    In Cocoa, I have an NSOutlineView where the cells are NSTextFieldCell. The cell displays values which are strings that are formatted according to certain rules (such as floats or pairs of floats with a space in between). I have made a custom NSFormatter to validate the text, and this seems to work with no problem. However, the cell (or the outline view, I'm unsure what is causing this) only seems to use the formatter at the moment my editing would end. If I type some alphabetic characters into the text field (which violates the formatting rules), these characters show up -- the only way I notice the formatter doing its job is that I'm now prevented from moving keyboard focus away from this cell. If I return the contents of the cell to a valid form, then I can move focus away. I have set both the cell and the outline view to be "continuous". It would be better if I was unable to enter text into the cell in the first place. Is it possible to make it like that, and if so, how?

  • Tool for parsing smtp logs that finds bounces

    - by Željko Filipin
    Our web application sends e-mails. We have lots of users, and we get lots of bounces. For example, user changes company and his company e-mail is no longer valid. To find bounces, I parse smtp log file with log parser. Some bounces are great, like 550+#[email protected]. There is [email protected] in bounce. But some do not have e-mail in error message, like 550+No+such+recipient. I have created simple ruby script that parses logs (uses log parser) to find which mail caused something like 550+No+such+recipient. I am just surprised that I could not find a tool that does it. I have found tools like zabbix and splunk for log analysis, but they look like overkill for such simple task. Anybody knows a tool that would parse smtp logs, find bounces and e-mails that cause them? Edit: smtp server is microsoft smtp server.

  • How come ftp protocol produces transmission errors sometimes if the data is using TCP, which is checksummed?

    - by Cray
    Every once in a while, downloading (especially large) files through ftp will produce errors. I am guessing that's also partly the reason why all major sites are publishing external checksums along with their downloads. How is this possible if ftp goes through TCP, which has checksum inbuilt and resends data if it is transmitted corruptly? One could argue that this is due to the short length of the CRC in the TCP protocol (which is 16bit I think, or something like that), and the collisions are simply happening too often. but 1) for this to be true, not only must there be a CRC collision, but also the random network error must modify both the CRC in the packet, and the packet itself so that the CRC will be valid for the new packet... Even with 16 bitCRC, is that so likely? 2) There are seemingly not many errors in, say, browsing the web which also goes through TCPIP.

  • Accessing structure elements using pointers

    - by Arun Nadesh
    Hi Everybody, Greetings! I got surprised when the following program did not crash. typedef struct _x{ int a; char b; int c; }x; main() { x *ptr=0; char *d=&ptr->b; } As per my understanding the -> operator has higher precedence over & operator. So I expected the program to crash at the below statement when we try to dereference the NULL pointer tr. char *d=&ptr->b; But the statement &ptr->b evaluates to a valid address. Could somebody please explain where I'm wrong? Thanks & Regards, Arun

Here's an expression I've written that does not work if the data in the field is null/nothing: =IIF( IsNumeric(Fields!ADataField.Value), RunningValue( IIF( DatePart("q", Fields!CreatedOn.Value) = "2", Fields!ADataField.Value, 0 ), Sum, Nothing ), Sum(0) ) (Pseudocode) "If the data is valid and if the data was created in the second quarter of the year, add it to the overall Sum, otherwise, add zero to the sum." Looks pretty straight forward. And the individual pieces of the expression work by themselves. IE: IsNumeric(), DatePart(), etc. But when I put them all together, the expression throws an error. I've attempted about every permutation of what's shown above, all to no avail. Null values in Fields!ADataField.Value cause errors. Thoughts?

  • multiple login pages in ASP.NET forms authentication

    - by Brad
    My bank's website has 2 login pages for online banking. On the first page, I enter my username. If I don't enter a valid username, I get an error message, and do not get to the 2nd page. The 2nd page displays a picture based on my user name, and has me enter my password. If I manually type a URL to a page inside the site after entering my username but before entering my password, I am redirected back to the first login page. Is there a good way to implement this in ASP.NET with Forms Authentication? I only get 1 loginUrl in my web.config. I am fairly certain my bank uses Java.

  • Jquery Live Function

    Hi! I want to make this script to work as LIVE() function.

  • Python + PostgreSQL + strange ascii = UTF8 encoding error

    - by Claudiu
    I have ascii strings which contain the character "\x80" to represent the euro symbol: >>> print "\x80" € When inserting string data containing this character into my database, I get: psycopg2.DataError: invalid byte sequence for encoding "UTF8": 0x80 HINT: This error can also happen if the byte sequence does not match the encodi ng expected by the server, which is controlled by "client_encoding". I'm a unicode newbie. How can I convert my strings containing "\x80" to valid UTF-8 containing that same euro symbol? I've tried calling .encode and .decode on various strings, but run into errors: >>> "\x80".encode("utf-8") Traceback (most recent call last): File "<pyshell#14>", line 1, in <module> "\x80".encode("utf-8") UnicodeDecodeError: 'ascii' codec can't decode byte 0x80 in position 0: ordinal not in range(128)

  • C# Login Dialog Implementation

    - by arc1880
    I have implemented a LoginAccess class that prompts the user to enter their active directory username and password. Then I save the login data as an encrypted file. Every subsequent start of the application, the LoginAccess class will read the encrypted file and check against the active directory to see if the login information is still valid. If it is not, then it will prompt the user again. I have made it so that the reading of the encrypted file and displaying of the login dialog is done on a separate thread. A delegate is fired when the login process is complete. The issue that I'm having is that I have a class that is used in multiple places. This class contains the call to the LoginAccess object. Every time I instantiate a new object there are multiple calls to the LoginAccess object and I get multiple dialogs appearing when it tries to prompt for a username and password. Any suggestions on how to have only one dialog appear would be greatly appreciated.

  • How the kernel gives seg. fault for a scenario like this?

    - by bala1486
    I have a doubt in accessing some invalid data. How will the OS cause segmentation fault for a scenario like this? Suppose a date segment has some 100 bytes. This will be mapped and a page table entry will be created. But the page size is 4K. Consider the data segment is aligned with this page boundary. So at first consider accessing a valid data within the 100 bytes. So now the page table entry is in TLB. Next if you try to access some invalid data between the 100 and 4K, the entry is there in page table and will it be allowed to access the invalid data??? Thanks, Bala

  • How do you implement Software Transactional Memory?

    - by Joseph Garvin
    In terms of actual low level atomic instructions and memory fences (I assume they're used), how do you implement STM? The part that's mysterious to me is that given some arbitrary chunk of code, you need a way to go back afterward and determine if the values used in each step were valid. How do you do that, and how do you do it efficiently? This would also seem to suggest that just like any other 'locking' solution you want to keep your critical sections as small as possible (to decrease the probability of a conflict), am I right? Also, can STM simply detect "another thread entered this area while the computation was executing, therefore the computation is invalid" or can it actually detect whether clobbered values were used (and thus by luck sometimes two threads may execute the same critical section simultaneously without need for rollback)?

  • Good input validation loop using cin - C++

    - by Alex
    Hi there, I'm in my second OOP class, and my first class was taught in C#, so I'm new to C++ and currently I am practicing input validation using cin. So here's my question: Is this loop I constructed a pretty good way of validating input? Or is there a more common/accepted way of doing it? Thanks! Code: int taxableIncome; int error; // input validation loop do { error = 0; cout << "Please enter in your taxable income: "; cin >> taxableIncome; if (cin.fail()) { cout << "Please enter a valid integer" << endl; error = 1; cin.clear(); cin.ignore(80, '\n'); } }while(error == 1);
