• Access DoCmd.OpenForm Not Working

  - by user961743

  Looking for a second set of eyes to figure out my problem with an Access form filter. I created a search form, when filled in, appends search criteria to a string variable (strQuery) that is put in place to the [WhereCondition] for opening a form. However, when the script is ran, nothing comes up except for a filtered form with no records. Here is the line that opens the form: DoCmd.OpenForm "ADD_NEW_NCMR", , , strQuery Before the line is ran, strQuery equals: 1=1 AND [NCMR].[NCMR_NUM] = '12-129' The form name, and table.column combination are all correct. In fact, using the DCount function returns the result of 1, which is correct for this query, and returns the correct number for other queries as well. This makes me think that there is nothing wrong with the where condition. DCount("[NCMR_NUM]", "NCMR", strQuery)

• Transfer of control and data between C and C#

  - by Prithvi

  C# main program needs to call a C program GA.c This C code executes many functions and one function initialize() calls objective() function. But this objective function needs to be written in C#.This call is in a loop in the C code and the C code needs to continue execution after the return from objective() until its main is over and return control to C# main program. C# main() { //code call to GA in C; //remaining code; } GA in C: Ga Main() { //code call to initialize function(); //remaining code } initialize funtion() in GA { for(some condition) { //code call to objective(parameter) function in C#; //code } } How do we do this?

• Techniques to Monitor cron tasks?

  - by Tristan Juricek

  Are there good techniques for monitoring cron tasks over a cluster? We're starting to use cron to launch tasks at daily intervals. A few ideas for checking out information: Add special application handling that logs information into some "network aware" place, like a DB Build up a logfile system that transfers the cron log periodically to a central point for processing/querying (along with other possible log files) I'm wondering if people have had success with doing things separately for cron versus other things, or, if the tasks were integrated into a different approach completely. I'm leaning towards #2, but I'd like to know what more experienced folk might try out.

• Programming issue while applying text to the third party control.

  - by srivatsa

  Hello I have used some third party controls in my windows application. There is a snippet which is being used in our code which re-initializes all the .text property of all the controls on the form. Everything works fine except for a control. This control is similar to the Windows Panel except for it has a dropdown appearance. This control has .Caption property instead of .Text property associated to it. This causes the problem whenever i use such codes foreach (Control oControl in this.Controls) { if (oControl is DropDownPanel) { { oControl.Text = rm_ResourceManager.GetString(oControl.Name + ".Text"); } } } The text is not set here for the DropDownPanel control in the above method. Since .Text is not available for DropDownPanel control. I cannot do the following either .. ((DropDownPanel)oControl).Caption = rm_ResourceManager.GetString(oControl.Name + ".Text"); Cos it shall throw exception if i try to cast oControl with that of DropDownPanel Any ideas how can i overcome such a condition. Regards

• How do I properly check if a program is a virus/trojan in VMware?

  - by acidzombie24

  How I should check if a program is a virus in VMware? Some programs I do need admin ability to install and it makes sense. But how do I know if it's doing more than I want? Some thoughts are: How many processes open when I launch the application What is added to the startup tab in msconfig If any services are added. That's pretty much all my ideas. Even if it does something I recognize I wouldn't know if it's necessary or not. What are some rule of thumb? -Edit- What about registries, can I use that information to help? Maybe have a scanner tell me if the application I just used has messed with sections (like bootup) it shouldn't have?

• reverse proxy http to tomcat

  - by John Q

  I've configured an Apache server with SSL and reverse proxy to a tomcat <VirtualHost domain.com:1443> [...] ProxyRequests Off ProxyPreserveHost On ProxyPass / http://local.com:8080/ ProxyPassReverse / http://local.com:8080 SSLEngine on [...] </VirtualHost> Tomcat is listening on 8080. The issue is that the app on tomcat is redirecting the request (HTTP 302 Moved temporairly). For example, if I use the URL https:// domain.com:1443/folder, reverse proxy launch the request http:// local.com:8080/folder, then, the app redirect to "/subfolder", so the final request is: http://domain.com:1443/folder/subfolder. Result is a 400 Bad request error code, as the request is HTTP on my SSL port. Do you know how I can fix this issue ? Thanks in advance.

• Sqlite3 activerecord :order => "time DESC" doesn't sort

  - by Ole Morten Amundsen

  rails 2.3.4, sqlite3 I'm trying this Production.find(:all, :conditions = ["time ?", start_time.utc], :order = "time DESC", :limit = 100) The condition works perfectly, but I'm having problems with the :order = time DESC. By chance, I discovered that it worked at Heroku (testing with heroku console), which runs PostgreSQL. However, locally, using sqlite3, new entries will be sorted after old ones, no matter what I set time to. Like this (output has been manually stripped): second entry is new: Production id: 2053939460, time: "2010-04-24 23:00:04", created_at: "2010-04-24 23:00:05" Production id: 2053939532, time: "2010-04-25 10:00:00", created_at: "2010-04-27 05:58:30" Production id: 2053939461, time: "2010-04-25 00:00:04", created_at: "2010-04-25 00:00:04" Production id: 2053939463, time: "2010-04-25 01:00:04", created_at: "2010-04-25 01:00:04" Seems like it sorts on the primary key, id, not time. Note that the query works fine on heroku, returning a correctly ordered list! I like sqlite, it's so KISS, I hope you can help me... Any suggestions?

• Troubleshooting a slow database server with no load

  - by user1721724

  I'm getting ready to soft launch my website and I've run into some problems with what I think is being caused by my MySQL database running on Fedora. All websites run fine, just as I'd expect, but any pages that establish a database connection hang until the connection is established, and then bang, the site loads as it should. Ex. My landing page (http://www.thrusong.com) doesn't make a database connection and loads quickly. User profile pages (http://www.thrusong.com/john) make a database connection and load slowly, even though most of the data comes from memcached and the database currently has no load on it. This problem just came up yesterday when my router died and I began using my Pace 2Wire modem with built-in router. Before, my old router was set to handle everything. My ISP says the settings in the modem are correct. Any ideas? Thanks in advance.

• JavaApplicationStub Compatibility with all java versions

  - by neelamsharma

  Hi, I am running a Java application on Mac Leopard & on Mac Mini. My Mac Mini upgraded, it is using Java Version 1.6.0_17 and Mac Leopard have version 1.5.0_13. To run that application on Mac Mini I have to copy JavaApplicationStub from path -"/System/Library/Frameworks/JavaVM.framework/Resources/MacOS/JavaApplicationStub" to my application "Content/Resources/Java". But this application successfully run on Mac Leopard. If I do not copy stub at Mac Mini then I am unable to launch application using app by double click, it shows icon for few second then disappears, so in that case I have to run application with its jar. I want that without copying explicitly JavaApplicationStub, how can I run app with all versions of java. If this possible then what changes I have to made? The info.plist file contain JVMVersion is 1.4+. Thanks!

• How do I set a property to the output of a command in msbuild/xbuild

  - by Nils

  In msbuild/xbuild I'd like to have a "libPath" property which can be ovveridden on the commandline using /p:libpath="/path/to/all/libs". But when this property is undefined I want to call pkg-config --retrieve-Path somePackage to get the current systems path. I thought like here I need the output of a command to be stored in a Property. The command always returns one line of output. I have tryied something like <PropertyGroup> <LibPath /> </PropertyGroup> <Task ....> <Exec Command="pkg-config --retrieve-Path somePackage" Condition="$(LibPath)' == ''"> <OutputTaskParameter="output" PropertyName="LibPath" /> </Exec> </Task> But that didn't work.

• Group policy doesn't let me execute Chrome (Win 7)

  - by George Katsanos

  where I work the admins just migrated us to Windows 7. They gave me admin rights but still I had to "run as administrator" my Google Chrome installation. After I managed to install it, I realized I even have to go through the 'run as administrator' shortcut every time I have to execute the application. I even edited the properties of the shortcut to check 'always run as administrator' but nothing changed. The message I get when I'm trying to launch Chrome is "This program is blocked by group policy. For more information contact your system administrator"... Is it something I could work out alone or I have to convince them to change the " policy " ?

• How can I tell when changes to jquery html() have finished ?

  - by mike_t2e

  I'm using jQuery to change the HTML of a tag, and the new HTML can be a very long string. $("#divToChange").html(newHTML); I then want to select elements created in the new HTML, but if I put the code immediately following the above line it seems to create a race condition with a long string where the changes that html() is making may not necessarily be finished rendering. In that case, trying to select the new elements won't always work. What I want to know is, is there an event fired or some other way of being notified when changes to html() have finished rendering ? I came across the jQuery watch plugin, which works alright as workaround but it's not ideal. Is there a better way ?

• Pin same app multiple times in Windows 7

  - by Mr. Shiny and New ??

  I use some programs with command line arguments and like to have shortcuts for launching those programs with those arguments. For example, I keep several Firefox profiles around and like to specify the profile name on the command line. Similarly I have several Eclipse shortcuts with a command line argument specifying the workspace to open. I would like to be able to pin these shortcuts to the start menu or taskbar in Windows 7. The problem I have is that once I've pinned one of these, no other shortcuts which launch the same exe can be launched. I'm also open to suggestions such as a suitable desktop gadget which can contain a bunch of arbitrary shortcuts, yet remain in a fixed position on my desktop somewhere, or some way of adding a secondary taskbar (this was possible in XP).

• How can I join on a CSV varchar?

  - by mgroves

  I have a varchar field that contains a string like "10,11,12,13". How can I use that CSV string to join to another table with those IDs? Here's the approach I'm taking now: select * from SomeTable a WHERE (',' + @csvString + ',') LIKE '%,' + CONVERT(varchar(25), a.ID) + ',%' Where @csvString is "10,11,12,...". I intend to use this method as a join condition as well. That method works, but it's rather slow (using CAST doesn't improve the speed). I understand that having CSVs in the database like that is usually a very silly idea in most cases, but there's nothing I can do about that.

• Is there a way to make 7zip temporarly uncompress the whole archive when double-clicking on an exe?

  - by Gnoupi

  In WinRAR, one feature which I like is the fact that you can set it to uncompress the whole archive in a temporary place, if you double-click on an .exe file inside the archive opened in WinRAR. Typically, I often download small games, which I just want to try, without the hassle of creating a folder for it, etc. Same for archives containing an installer with its own separate files. In the 7-zip window, if I double-click an exe, it will just extract the exe in a temporary location and launch it. In the small game context (or installer), it means that it will simply fail, because it will miss required files in the same folder. So my question is: Is there a way to make 7-zip extract the whole archive in a temporary folder when launching an exe from inside the archive?

• jQuery/Asp.Net mvc username lookup

  OK, for the life of me I can't uderstand why the follwing code is always returning false?? I have debugged with firefox to see what going on, but the function seems to always return false even when the condition username taken is 0(false), here is the jquery code: function CheckAvailability() { showLoader(); $.post("/Account/CheckUsernameAvailability", { userName: $(profile_username).val() }, function(data) { var myObject = eval('(' + data + ')'); var newid = myObject; if (newid == 0) { profile_username_error.removeClass("field_not_valid"); profile_username_error.addClass("field_valid"); $("#validUserName_msg").html("<font color='green'>Available</font>") return true; } else { profile_username_error.addClass("field_not_valid"); profile_username_error.removeClass("field_valid"); $("#validUserName_msg").html("<font color='red'>Taken</font>") return false; } }); } I'm using the /Account/CheckUsernameAvailability to check if a given name is take or not, it not taken(0) should return true, false otherwise.

• Windows Media Center Missing?

  - by Eric

  I'm running Windows Vista SP2 64-bit, but it was SP1 when I bought the laptop. It came with Windows Media Center, but I originally found no use for it, so I deleted the shortcut. Now I DO want to use it, and I can't find it anywhere. However, when I insert a DVD, the option to play it with Windows Media Center will appear, and it will launch Windows Media Center, so I must still have it on my system somewhere. My question is, where? Is there an easy way to just run the program using the Run window?

• How to prevent HP Photosmart Essential from launching on removal drive insertion

  - by David Boike

  My in-laws bought an HP computer loaded with HP junk, and it's giving me a headache. When they insert a camera memory card into their printer, the Auto-Play dialog comes up, but it also launches the HP Photosmart Essential application, which is a piece of trash. It will NOT launch properly just normally from the taskbar, so that makes it pretty useless. I tried uninstalling it, but then when you insert a memory card, a Microsoft Help window comes up saying how to reinstall HP Photosmart Essential!! Is there any way to find the registry key (I assume) that allows a program to be launched when a memory card is inserted?

• PHP: Using browscap.ini on shared host. - ini_set() failing

  - by GreybeardTheUnready

  I'm trying to use get_browser() , unfortunately my page is on a shared host, and I have no access to php.ini. I have downloaded the latest version of browscap.ini and placed in my document root. I have then added the following:- if (!ini_set('browscap', '/home/private stuff/browscap.ini')) { echo "Failed to set browscap"; } else { echo "browscap = [" . ini_get('browscap') . "]"; } exit(); But this fails, (nb: the echo statement for the failed condition always shows [] - even if I didn;t have the browscap.ini file the setting should still show up in the ini_get.... shouldn't it?) I have looked at the previous questions on this and they don't seem to help, any ideas?

• Ubuntu 10.04 User Interface errors

  - by user306668

  Hi Guys Using Ubuntu 10.04 Beta on a Sony Vaio laptop (slightly old PCG-4n7M). It was working wonderfully until this morning. After updating and upgrading the login screen images gave broken image icons, then on logging in UI was replaced with just the cmd shell. All menus are gone. I have tried to reconfigure xserver-xorg and that doesn't work. Reinstalling doesn't either. I have tried a number of other attempts. What is weird is that I can launch graphical applications from the cmd line. such as firefox or google-chrome. and they work but the UI is simplified or broken (no resizing, closing, minimizing). I am a bit lost on how to fix this error. If anyone has any suggestions, please let me know

• How can I synchronize database access between a write-thread and a read-thread?

  - by Runcible

  My program has two threads: Main execution thread that handles user input and queues up database writes A utility thread that wakes up every second and flushes the writes to the database Inside the main thread, I occasionally need to make reads on the database. When this happens, performance is not important, but correctness is. (In a perfect world, I would be reading from a cache, not making a round-trip to the database - but let's put that aside for the sake of discussion.) How do I make sure that the main thread sees a correct / quiescent database? A standard mutex won't work, since I run the risk of having the main thread grab the mutex before the data gets flushed to the database. This would be a big race condition. What I really want is some sort of mutex that lets the main thread of execution proceed only AFTER the mutex has been grabbed and released once. Does such a thing exist? What's the best way to solve this problem?

• How sql server evaluates the multiple different joins?

  - by ziang

  Hi, i have a general question about how sql server evaluates the joins.The query is SELECT * FROM TableA INNER JOIN TableB ON TableB.id = TableA.id LEFT JOIN TABLEC ON TABLEC.id = TABLEB.id Q1: What tables is the left join based on? I know it will based on the TABLEC but what is the other one? Is it the result of the first inner join or the TABLEB specified in the left join condition? Q2: Is "LEFT JOIN TABLEC ON TABLEC.id = TABLEB.id" equivalent to "LEFT JOIN TABLEC ON TABLEB.id = TABLEC.id" Q3: Is the query equivalent to the following one? (with TABLEB.id replaced by TABLEA.id?) SELECT * FROM TableA INNER JOIN TableB ON TableB.id = TableA.id LEFT JOIN TABLEC ON TABLEC.id = TABLEA.id Thank you!
