• DataBind and Postback

  - by Michael La Voie

  This is a general how does DataBind work questions... I have a simple page with a GridView that is bound (in the aspx code) to an ObjectDataSource. I can look in the Select() function called by the ObjectDataSource to see that it is called on the initial load and on every post back. I have some logic that happens on post backs that will affect the GridView's data, and I want to call GridView.DataBind() later on in the post back, after I've made some changes. Is there a way to prevent the automatic rebinding that happens on each post back? Does this mean I can't use an ObjectDataSource for this control?

• Microsoft Driver Verifier

  - by Benjamin

  In Verifier Dialog, there is a window to select drivers to verify. The list control has 4 column. 1. Verify? 2. Driver name. 3. Provider 4. Version My driver's provider and version are represented as "unknown". I don't know how can I set these values. Where can I set this value? By SignTool? Or Resource file? Yes, this is not a big problem. But I would like to correct that. Let me know please. Thanks.

• javax.servlet import cannot be resolved after moving web servlet

  - by Michael Kjörling

  I have written a small web servlet to run under Tomcat, using Eclipse Helios. In its old, non-source-controlled location, everything was fine, but now I need to add this to our source control system. Moving the old files out of the way, creating a new workspace, setting up the server connection and copying and importing the existing projects into the new workspace all worked fine once I figured out how to do it, but I can't get the servlet to build. Instead, I get a whole bunch of cannot be resolved to a type errors talking about various servlet class types; HttpServlet, HttpServletRequest, ServletException, etc. Another error that is almost certainly related is The import javax.servlet cannot be resolved. I am obviously missing something very basic, but I'm new to this (and not having the terminology really down pat probably doesn't help me Google for an answer). Any suggestions as to what I might be missing would be greatly appreciated.

• [WM6] Owner of a component. What exactly is this for?

  - by kornelijepetak

  I am developing an app for Windows Mobile 6 and there is a CameraCaptureDialog class that enables me to call a camera app from my own application. The class has an Owner property that most examples on the internet set to "this". cam.Owner = this; What exactly does this do? I've seen a similar scenario with Windows Forms components/controls by setting the Parent control. In that case I guess it's used only for layout algorithms, but other than that, is there any useful purpose? I don't see how setting an owner of the CameraCaptureDialog can (and actually does not) make any difference (at least not a visible one). Any insight would be appreciated.

• Get CruiseControl to talk to github with the correct public key.

  - by Danny Lister

  Hi All, Has anybody installed git and ControlControl and got CruiseControl to pull from GitHub on a window 2003 server. I keep getting public key errors (access denied) - Which is good i suppose as that confirms git is talking to github. However what is not good is that I dont not know where to install the rsa keys so they will be picked up by the running process (git in the context of cc.net). Any help would save me a lot of hair! I have tried installing the keys into; c:\Program Files\Git.ssh Whereby running git bash and cd ~ take me to: c:\Program Files\Git Current error from CC.net is Error Message: ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: Permission denied (publickey). fatal: The remote end hung up unexpectedly . Process command: C:\Program Files\Git\bin\git.exe fetch origin Thanks in advance

• Get the tags of a document in Subversion

  - by Onno

  I was wondering if there is a way to easily see the tags of a specific file in Subversion using the command line and/or TortoiseSVN. Most version control system allow you to see easily access the tags/labels of a file. When using TortoiseSVN I can do this when I access the "Revision Graph". This however is a operation that takes around 44 minutes. I consider this very hard work just to know what tags have been created for the file. Is there another way to do it? Or is there no way to instantaneously access tag information. Thanks, Onno

• Displaying current time above the thumb of a slider in Silverlight

  - by Scharrels

  I've made a time slider in Silverlight. To style it, I've made a control template and modified the style. I've added a text field above the thumb (always centered above the thumb), which should display the time. However, I can't find any way to access the slider information (e.g. current value) or find another way to pass any information to the style, which I can then data bind to the text field. So my question in short: how can I display time information above the thumb?

• Simple WCF question.

  - by bearrito

  So I am learning WCF and I have run across an issue that I believe has to do with Instance Control/State but I am not sure. Workflow is as follows, Basic client/server paradigm. The client calls a Method RetrieveBusinessObjects(criteria) and the server calls the datalayer and then puts them in an IList on the server side. It does not return this list to the calling Client. The client would then call a method say DisplayBusinessObjects() which would retrieve the IList from the Server, serialize them, bring them across the wire and display them. If i try this using the WCFTestClient it works. If I run it from an actual client then I get back an BusinessObject[] of size 0. Which to me indicates I had no objects to return. Is that a state mgmt issue or am I missing something?

• Custom DataGridView column sort based on Value not Formatted value

  - by Dan Neely

  I have a custom DGV cell I'm using to display the contents of MyType objects. To control how they're being formatted I'm overriding the GetFormattedValue() and FormattedvalueType methods of DataGridViewTextBoxCell because in this case I don't want to use the default ToString() method. The problem is that when I do this the DGV is sorting the column by the string in FormattedValue instead of by Value. I'm not seeing a method I can override to change the sort behavior of the column. While I know I can, I don't want to have to write custom Sort mthods for the DGVs themselves because I'm using this in multiple DGV's.

• A consistent and simple group of IDE and tools for embedded code and unit test in C++ ?

  - by TridenT

  I’m starting a new firmware project in C++ for Texas Instrument C283xx and C6xxx targets. The unit tests will not run on the target, but will be compiled with gcc/gcov on a PC with windows (and run as well on PC) with simple metrics for tested code coverage. The whole project will be part of Cruise Control.NET for continuous integrations. My question is: what are the consistent IDE / framework / tools to work together? A/ One of the developers says CodeComposerStudio V3.1 for application and CodeBlocks + CxxUnit for the Unit tests. B/ I’m more attracted with CodeComposerStudio V4 for application, Eclipse CDT (well, as CCS V4) and CppUnit for unit test + MockCpp for mocks. I don’t want the best in class tools for each process, but a global, consistent and easy solution (or group of tools if you prefer).

• How to propose Asp.Net Mvc over other technologies to client?

  - by Arnis L.

  How to show benefits of adopting asp.net mvc to client? I mean - we as developers can understand benefits of easier implementation of automated testing, better control over rendered html etc., but what would be strongest motives for client to accept usage of asp.net mvc? Maybe there's some more nice looking examples built with asp.net mvc (excluding stackoverflow) to show? p.s. Please, do not start flame war. In this case - it doesn't matter if asp.net mvc is better than x or vica versa.

• Drag and drop + custom drawing in Android

  - by Rich

  I am working on something that needed custom drag-and-drop functionality, so I have been subclassing View, doing a bunch of math in response to touch events, and then rendering everything manually through code on the canvas in onDraw. Now, the more functionality I add, the more the code is growing out of control and I find myself writing a ton more code than I would expect to write in a high level environment like Android. Is this how it's done, or am I missing something? If I'm not doing anything fancy in the UI, the framework handles the majority of my interactions. Built-in controls handle the touches and drags, and my code is pretty much limited to business logic and data. Is there a way to leverage the power of some of the UI controls and things like animations while also doing some of it manually in the onDraw canvas? Is there an accepted standard of when to use one or the other (if indeed the two approaches can be mixed)?

• When do I need to deallocate memory?

  - by extintor

  I am using this code inside a class to make a webbrowser control visit a website: void myClass::visitWeb(const char *url) { WCHAR buffer[MAX_LEN]; ZeroMemory(buffer, sizeof(buffer)); MultiByteToWideChar(CP_ACP, MB_ERR_INVALID_CHARS, url, strlen(url), buffer, sizeof(buffer)-1); VARIANT vURL; vURL.vt = VT_BSTR; vURL.bstrVal = SysAllocString(buffer); // webbrowser navigate code... VariantClear(&vURL); } I call visitWeb from another void function that gets called on the handlemessage() for the app. Do I need to do some memory deallocation here?, I see vURL is being deallocated by VariantClear but should I deallocate memory for buffer? I've been told that in another bool I have in the same app I shouldn't deallocate anything because everything clear out when the bool return true/false, but what happens on this void?

• Program LED with just USB port

  - by LifeH2O

  I want to control LED with C# using only USB port. I don't want to attach any other device with USB. I just want to attach LED directly to USB port pins and program it (blink etc). How can i do that? I am new to hardware programming and it will be my first program. EDIT: I can do it already (blink LED) using printer port by attaching one led pin to data pin and other to ground. How can i do the same with USB port? My motherboard does not have a printer port. USB is the only option.

• How do I process a jQuery SVG group event in a single handler?

  - by rmflow

  I'm trying to draw a button using jQuery SVG, the button is a filled rect and the text is placed on top of the rect. Rect and text are grouped and I want to control the mouseover/mouseout events. The problem is: mouseover/mouseout events are triggered separately for every element of the group. Is it possible to make a single event handler for entire group? Here is an example: gClear = svg.group(); btClear = svg.rect(gClear, 10, 10, 100, h-20, 5 ,5, attrs); txtClear = svg.text(gClear, 35, 30, "Clear", {fontFamily: "Verdana", fontWeight: "bold", fontSize: "16px"}); $(gClear, svg.root()).bind("mouseover", function() { $(btClear).animate({svgFill: '#adf'}, 100); }).bind("mouseout", function() { $(btClear).animate({svgFill: '#fff'}, 100); }) When I move the mouse inside the rect the events mouseover/mouseout are triggered. Can I make "text" events transparent or can I have a single event handler for the group?

• MySQL import in phpmyadmin (CSV) chokes on quotes

  - by Andrew Swift

  I am trying to import a .csv file into a MySQL table via phpMyAdmin. The .csv file is separated by pipes, formated like this: data|d'ata|d'a"ta|dat"a| data|"da"ta|data|da't'a| dat'a|data|da"ta"|da'ta| The data contains quotes. I have no control over the format in which I recieve the data -- it is generated by a third party. The problem comes when there is a | followed by a double quote. I always get an "invalid field count in CSV input on line N" error. I am uploading the file from the import page, using Latin1, CSV, terminated by |, separated by ". I would like to just change the "enclosed by" character, but I keep getting "Invalid parameter for CSV import: Fields enclosed by". I have tried various characters with no success. How can I tell MySQL to accept this format in phpMyAdmin? Setting up these tables is the first step in writing a program that will use uploaded gzipped .csv files to maintain the catalog of an e-commerce site.

• No Carbon Human-Interface-Toolbox in OSX 64-bit binaries?

  - by yairchu

  I get the impression that Carbon Human Interface Toolbox does not work in 64-bit binaries. Apple's documentation says: The Carbon Help Manager is not available to 64-bit applications. ... The Control Manager is not available to 64-bit applications. ... The Data Browser is not available to 64-bit applications. ... I just want to verify that: There is no work-around around this. If this is simply the case. Why don't Apple's documentation simply state it as such?
