• 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)

• ASP.Net Gridview, How to activate Edit Mode based on ID (DataKey)

  - by Jon P

  I have a page, lets call it SourceTypes.aspx, that has a a GridView that is displaying a list of Source Types. Part of the GridView is a DataKey, SourceTypeID. If source TypeID is passed to the page via a query sting, how to I put the Gridview into Edit mode for the appropriate row based on the SourceTypeID? The GridView is bound to a SQlDataSource object. I have a feeling I am going to kick myself when the answer appears!! I have looked at Putting a gridview row in edit mode programmatically but it is some what lacking in specifics

• 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?

• Python: UTF-8 problems (again...)

  - by blahblah

  I have a database which is synchronized against an external web source twice a day. This web source contains a bunch of entries, which have names and some extra information about these names. Some of these names are silly and I want to rename them when inserting them into my own database. To rename these silly names, I have a standard dictionary as such: RENAME_TABLE = { "Wsird" : "Weird", ... } As you can see, this is where UTF-8 comes into play. This is the function which performs renaming of all the problematic entries: def rename_all_entries(): all_keys = RENAME_TABLE.keys() entries = Entry.objects.filter(name__in=all_keys) for entry in entries: entry.name = RENAME_TABLE[entry.name] entry.save() So it tries to find the old name in RENAME_TABLE and renames the entry if found. However, I get a KeyError exception when using RENAME_TABLE[entry.name]. Now I'm lost, what do I do? I have... # -*- coding: utf-8 -*- ...in the top of the Python file.

• VS2008 is very slow on a specific large C++ solution

  - by VioletRose

  I have a solution with 21 C++ projects and 1 VB.NET project. The IDE responds very slowly when I simply move the carret in a file or try to open the menu. The process seems to take 50% of CPU for each movement. It only happens with this solution and only on my machine. The solution has total of 2380 source and header files, of which 1280 are header files. I tried to remove all connection to the source control (Perforce) but it didn't help. Also, I have Visual Assist installed but even after removing it (uninstall), the same behavior continued. Any idea?

• Targeting an iFrame once with jQuery

  - by user275074

  Hi, I have a series of frames (4) which are used in a page to create loading of dynamic content through Ajax calls. In each of these frames I target parent level elements and update them with there respective content e.g. $("#loadingGrid1",top.document).show(); $("#frameSkills",top.document).hide(); In jQuery is there a way to instead of targeting specific elements on the parent page multiple times, simply target the page once into a variable e.g. var parentPage=$('#frameSkills',top.document); And then use this variable to apply content like $(parentPage #loadingGrid1).hide() Hope I've explained what I'm after enough. Basically, I'm having to call "top.document" in every jQuery selector I make and it seems like a waste of energy.

• 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.

• 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

• C# How to Identify Caller for Template Events

  - by mikeknoop

  I have a ListBox container data bound and templatized as so: <ListBox x:Name="ListBox" ItemsSource="{Binding Source={StaticResource List}}" ItemTemplate="{StaticResource ListTemplate}"> </ListBox> Within my ListTemplate resource, I define a Grid which contains a few child elements. I have setup a click event handler on one of child elements. The event hander is not row-specific, and I need a (best practice) way of identifying which row in the ListBox the event fired upon. From my data source, I have an unique ID which corresponds to the row. I do not currently expose this ID in the data binding, though could. Ideally I would like the event handler to be able to identify the ID of the row the event was fired upon. Thank you!

  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.

• 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;

• ASP.Net aspx markup

  - by Batuta

  I am working on some old web forms application. When I changed from design to view source of the aspx page, the aspx markup becomes disarranged. For example, a label is written as follows: <asp:label id="Label20" style="Z-INDEX: 119; LEFT: 16px; POSITION: absolute; TOP: 424px" runat="server" Height="24px" Width="72px">Instructions:</asp:label> It suddenly becomes like this (when I toggle from design to source) <asp:label id="Label20" style="Z-INDEX: 119; LEFT: 16px; POSITION: absolute; TOP: 424px" runat="server" Height="24px" Width="72px">Instructions:</asp:label> Notice that the alignment and margins, tab stops are changed. Any idea how to prevent VS from doing this? Thanks.

• 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 .]

• 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.

• 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?

• Merging XMLTextReaders in C#

  - by smithchelluk

  I have a website that needs to pull information from two diffferent XML data sources. Originally I only need to get the data from one source so I was building a URL in the backend that went and retrieved the data from the XML site and then parsed and rendered it in the front end of the website. Now I have to use a 2nd data source and merge the result sets (which are identically structured XML) into one result set. Here is the code I am currently using to get one XML feed. sUrl = sbUrl.ToString(); //The URL for the XML feed XmlDocument xDoc = new XmlDocument(); StringBuilder oBuilder = new StringBuilder(); //The parsed HTML output XmlTextReader oXmlReader = new XmlTextReader(sUrl); oXmlReader.Read(); xDoc.Load(oXmlReader); XmlNodeList List = xDoc.GetElementsByTagName("result"); foreach (XmlNode node in List) { XmlElement key = (XmlElement)node; //BUILD THE OUTPUT HERE } Thanks in advance for your help.

• 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!

• How do I setup Eclipse to stop on the line an exception occured?

  - by Chris Persichetti

  Hi, How can I setup Eclipse to stop at the point an exception occurred. I have an Eclipse breakpoint setup to break on an exception. In the code example below, the problem I'm having is Eclipse tries to open the Integer source code. Is there any way to just have debugger break at the point shown in my code example? If I move down the stack trace, I will get to this line, it'd be nice if there's a way to do this without the "Source not found" window coming up. This can be done in Visual Studio, so it's driving me crazy not being able to find a way to do this in Eclipse. package com.test; public class QuickTest { public static void main(String[] args) { try { test(); } catch(NumberFormatException e) { System.out.println(e.getMessage()); } } private static void test() { String str = "notAnumber"; Integer.parseInt(str);//<----I want debugger to stop here } }
