  • Handling multiple post-defined datasource connections based on user

    - by choudeshell
    How should I handle multiple user-connection defined datasource connection in my .NET application? To illustrate this better; the user provides three (3) pieces of information, username, password and data source name. This data source name is then looked-up in a central database telling that application which main database this user should connect to. My question is, in the DataAccess layer, should we only pass down enough information to uniquely identify that user, and query the central database each time in the DAL; or, should we provide another way to pass the datasource connection down to the DAL?

  • Query MS Access database in VB 2008

    - by Logan
    Hi, I added an Access database as a Data Source in VB 2008. I want to query this database and use the information in various ways throughout the program. For example, there is an Employee table with first/last names of employees. I have a combobox on my form that I want to display all of the employees. So I want to query the database for all the rows in the Employee table, and add them to the combobox as I go. I am familiar with SQL Syntax, so I am not asking how to write the query itself, but rather how to fetch rows in VB code (mimicking php's mysql_fetch_assoc and mysql_connect essentially) Thanks! Edit: Also, I want to know if I can query a DB if I don't add it as a data source (if I know the path name of the database)

  • Initialise a wix CheckBox's check state based on a property?

    - by MauriceL
    How does one initalise a Wix check box based on the value of a property? So far, I've done the following: <Control Id="Checkbox" Type="CheckBox" X="0" Y="0" Width="100" Height="15" Property="CHECKBOX_SELECTION" Text="I want this feature" CheckBoxValue="1" TabSkip="no"> <Condition Action="hide">HIDE_CHECKBOX</Condition> <Condition Action="show">NOT HIDE_CHECKBOX</Condition> </Control> Currently I have two custom actions to set HIDE_CHECKBOX and CHECKBOX_SELECTION. The CHECKBOX_SELECTION custom action occurs immediately after the HIDE_CHECKBOX action. What I'm seeing is that HIDE_CHECKBOX is behaving correctly (ie. the checkbox is hidden) which suggests that I've got the ordering of custom actions correct, but CHECKBOX_SELECTION is not changing the check state of the check box. Is this a safe assumption? Also, I've confirmed that SELECTION is being set to '1' in the logs.

  • How are OpenGL programs debugged?

    - by manasij7479
    I'm trying to find what is causing a segfault when glDrawArrays is called (as gdb says) in my simple program. When I use the OpenGl calls directly, the program runs fine. But when I wrap them up into two classes (under construction, of vao and vbo) the program segfaults. So, in my wrappers, I definitly disabled something or set something I'm not supposed to. My question is, how do I get some diagnostics that will help me pinpoint the source of the problem ? I'm looking for something similar to what glGetShaderiv does, but for vao and vbo s, that will tell me if I have..say.. unbound a buffer by mistake. [I'm not posting the code here, but if any of you want to donate some time by testing a segfaulting example, here is a tar.gz of the source . You'll need working libraries of sfml-2.0rc, glew and gcc=4.6 .]

  • servlet authentication and further reference to the credentials

    - by user553592
    What I got so far: It all begins with an HTML form which prompts the user for a username and password. From there it post the acquired user/pass to a servlet, GateKeeper. GateKeeper determines if the user/pass combination match any records in the MySQL database. Here is the sql I use: SELECT id FROM Users WHERE username='?' AND password=MD5('?') where the ? indicate information provided the previous HTML form. What I need now: I need some way to store the username and id of the record in the database. GateKeeper redirects the user to a control panel upon success. Therefore, I need a method to reference the username to display simple greetings, etc and also the id so it eliminates unnecessary calls to the database. The control panel may make AJAX calls to Servlets that preform some sort of task to the MySQL database.

  • Makefile won't copy .o to obj/ and target to bin/ folders

    - by about blank
    I'm trying to write a Makefile which will copy its target and objects to bin/ and obj/ directories, respectively. Yet, when I try to run it I get the following error: nasm -f elf64 -g -F stabs main.asm -l spacelander.lst ld -o spacelander obj/main.o ld: cannot find obj/main.o: No such file or directory make: *** [spacelander] Error 1 Why is this happening? Update I noticed when I posted the error that it was due to white spacing errors. After taking care of those, I still get the new error I replaced with the old one I mentioned prior. What is this?? Update 2 Posted -d flag output below Makefile source. Source ASM := nasm ARGS := -f FMT := elf64 OPT := -g -F stabs SRC := main.asm OBJDIR := obj TARGETDIR := bin OBJ := $(addprefix $(OBJDIR)/,$(patsubst %.asm, %.o, $(wildcard *.asm))) TARGET := spacelander .PHONY: all clean all: $(OBJDIR) $(TARGET) $(OBJDIR): mkdir $(OBJDIR) $(OBJDIR)/%.o: $(SRC) $(ASM) $(ARGS) $(FMT) $(OPT) $(SRC) -l $(TARGET).lst $(TARGET): $(OBJ) ld -o $(TARGET) $(OBJ) clean: @rm -f $(TARGET) $(wildcard *.o) @rm -rf $(OBJDIR) make -d Output - NOTE: output is too many characters for body, thus is pastebinned http://pastebin.com/3bctGJxs

  • Flex 4: Loading XML into a Model Actionsript Class

    - by Steve
    I'm trying to create an actionscript class to serve as a data model for my Flex app. I already have a formatted XML file to read from, and when I was simply declaring the data service in my MXML app I used this code inside the declarations: I'm now trying to create a model class and can't seem to get the same functionality. I've tried importing mx.rpc.http.HTTPService but i think this is different. And using the XML class doesn't seem to allow the ability to define a source url. I'm assuming that I am able to declare a public var inside my class that will read this XML source file as I had done in the main app. If this is possible, how do I do it?

  • Fancybox2 Inline Content Gallery

    - by beefchimi
    I am trying to create a gallery of inline content with Fancybox 2, and am failing miserably. I checked out some other resources online and they seem to indicate doing this relatively easily, yet, I cannot seem to get it to work. Here is my fiddle: http://jsfiddle.net/beefchimi/jtxHd/2/ Now, I feel like the fiddle is not loading the resources, so thats a problem. But even with the resources this does not work, I get the fancybox error. Resources: http://fancyapps.com/fancybox/source/jquery.fancybox.pack.js?v=2.1.3 http://fancyapps.com/fancybox/source/jquery.fancybox.css?v=2.1.3 Any help would be greatly appreciated. EDIT: So I can't submit my question without including some code, because linking to jsfiddle isn't okay, so, here is my fancybox initialization, which you will also find in the jsfiddle: $(document).ready(function() { $('a.inlinepopup').fancybox({ 'width' : '75%', 'height' : '75%', 'autoScale' : false, 'type' : 'iframe' }); });

  • Why is the page still caching even after the no-cache headers have been sent?

    - by Matthew Grasinger
    I've done a ton of research on this and have asked many people with help and still no success. Here are the details... I'm involved in developing a website that pulls data from various data files, combines them in a temp .csv file, and then is graphed using a popular graphing library: dygraphs. The bulk of the website is written in PHP. The parameters that determine the data that is graphed are stored in the users session, the .csv is named after the users session and available for download, and then the .csv file is written in a script that passes it to the dygraphs object. And we've found, even with the no-cache headers sent: header("Cache-Control: no-cache, must-revalidate"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); Many users experience in the middle of a session, (if enough different graphs are generated) the page displaying an older, static rendering of the page (data they had graphed earlier in the session) as if it were cached and loaded instead of getting a new request. It only gets weirder though: I've checked using developer tools in both Firefox and Chrome and both browsers are receiving the no-cache headers just fine; Even when the problem occurs if you view the page source, the source is the correct content (a table/legend is also dynamically created using php, the source shows the correct table, but what is rendered is older content); the page begins to render correctly until the graph is about to be display, and then shows the older content; the older content displays as if it were a completely static overlay--the cached graph does not have the same dynamic features (roll over data point display, zoom and pan, etc.) And it is as if the correct page were somewhere beneath it (the download button for the csv file moves depending on how large the table is. The older, static page does nothing if you click the download .csv button, but if you can manage to find the one in the page beneath it you can click and still download the .csv. The data in the .csv is correct) It is one of the strangest things I've seen in development thus far. Some other relevant facts are that all the problems I've personally experience occurred while I was using Chrome. Non of these symptoms have been reported by Firefox users. IE users have had the same problems (IE users are forced to use chrome frame). I'm at my wits end at this point. We've sent the php headers; we've tried setting the cache profile for php on IIS as "DisableCache" (or whatever); we've tried sending a random query string to the results page; we've tried all the appropriate meta tags--all with no success.

  • Running android application on windows, developed on linux

    - by PankTrip
    Hi, I'm very new to Android development. I want to run an Android application on Windows using eclipse that has been already developed on Linux OS. I tried to copy the source/res and menifest file of Android application form linux and started creating a new project on windows. I tried to replace the source/res and menifest of newly created Project on windows with one on linux. It was unable to generate R.java file. I wonder if java is portable accross platform then why I couldn't create and compile a new project on Windows from Linux. Thanx in advance.

  • How do I remove line references in generate output in doxygen?

    - by MeThinks
    I want to remove lines look as follows but I still want to return source code browsing Definition at line 377 of file xxx.h. I have tried the following two in the doxygen config file but these just remove cross references on types # If the REFERENCES_RELATION tag is set to YES # then for each documented function all documented entities # called/used by that function will be listed. REFERENCES_RELATION = NO # If the REFERENCES_LINK_SOURCE tag is set to YES (the default) # and SOURCE_BROWSER tag is set to YES, then the hyperlinks from # functions in REFERENCES_RELATION and REFERENCED_BY_RELATION lists will # link to the source code. Otherwise they will link to the documentation. REFERENCES_LINK_SOURCE = NO update: I've just trying setting the following and seems to do the jobs but waiting to confirm if this is the correct way of achieving what I want SOURCE_BROWSER = NO

  • Do sfSubForm.fForm.RecordSource and Forms(fForm).RecordSource refer to the same object and property?

    - by Raymond Rosalind
    Hi, this has me pretty confused and I can't find the answer anywhere else so thought I'd post here to see if anyone can help! I have a form in an Access 2007 database with a subform (sfSubform) embedded in it. The subform control's SourceObject is set to be another form (fForm). fForm's RecordSource starts out as a table. At one point I want to change the data displayed in the subform to the result of a SQL statement, so I use sfSubform.Form.RecordSource = strSQL. This works fine. However, if I ouput the name of the RecordSource for fForm after making this change, it still gives the name of the table that I orginially set. Does sfSubform.Form.RecordSource not change the source of fForm? Is it a copy of fForm that is embedded in the control? Hope all that makes sense.

  • set label text to total row count of gridview

    - by woolardz
    I'm using a stored procedure in a sql database as the data source for a SqlDataSourceControl on my .aspx page. I'm then using the SqlDataSourceControl as the data source for a gridview on my page. Paging is set to true on the gridview. What i would like to do is set the text of a label to the total number of rows in the gridview. I can use this code 'labelRowCount.Text = GridView2.Rows.Count & " layers found" to return the number of results per page, but it doesn't give me the total. I've looked in several places and haven't been successful in finding a solution.

  • Problem in the Android documentation

    - by Nick
    Hi all, This is my first post ever -- I love the Android SDK (been at it for a week), but I did notice a small typo in the official documentation that needs correcting. Not sure if this is where I post it, but on this page: http://developer.android.com/reference/android/os/CountDownTimer.html within the example source code, the source says "CountdownTimer" on line one when it should say "CountDownTimer" (notice the capitalization of the letter "D"). An easy fix for one with programming experience, but the code as written will not compile, which could be confusing for someone using this code for the first time. Is this where documentation bugs are submitted, and if not, where should I go to request the fix? Thanks all!

  • UI updates not happening in the expected order

    - by allonym
    I have a Panel which hosts a number of child controls in a grid layout. The child controls each consist of a Panel with a PictureBox and a Label. When one of these child controls is clicked it becomes "selected" (which basically entails changing its background to a different color) and an event is fired. In the handler for this event, an image is displayed in a PictureBox on a separate form. In code, the background of the child control is definitely changed before firing the event, but for some reason it never updates at runtime until after the image has updated in the other Form. I've tried to Invalidate() and Refresh() the child control before firing the event, without effect. Why is this happening, and what can I do to set it right?

  • Python "string_escape" vs "unicode_escape"

    - by Mike Boers
    According to the docs, the builtin string encoding string_escape: Produce[s] a string that is suitable as string literal in Python source code ...while the unicode_escape: Produce[s] a string that is suitable as Unicode literal in Python source code So, they should have roughly the same behaviour. BUT, they appear to treat single quotes differently: >>> print """before '" \0 after""".encode('string-escape') before \'" \x00 after >>> print """before '" \0 after""".encode('unicode-escape') before '" \x00 after The string_escape escapes the single quote while the Unicode one does not. Is it safe to assume that I can simply: >>> escaped = my_string.encode('unicode-escape').replace("'", "\\'") ...and get the expected behaviour?

  • Similar code detector

    - by Let_Me_Be
    I'm search for a tool that could compare source codes for similarity. We have a very trivial system right now that has huge amount of false positives and the real positives can easily get buried in them. My requirements are: reasonably small amount of false positives good detection rate (yeah these are going against each other) ideally with a more complex output than just a single value usable for C (C99) and C++ (C++03 and optimally C++11) still maintained usable for comparing two source files against each other usable in non-interactive mode EDIT: To avoid confusion, the following two code snippets are identical and should be detected as such: for (int i = 0; i < 10; i++) { bla; } int i; while (i < 10) { bla; i++; } The same here: int x = 10; y = x + 5; int a = 10; y = a + 5;
