• How do you read data from a ADODB stream in ASP as byte values?

  - by user89691

  I have an ASP routine that gets a binary file's contents and writes it to a stream. The intention is to read it from the stream and process it st the server. So I have: ResponseBody = SomeRequest (SomeURL) ; var BinaryInputStream = Server.CreateObject ("ADODB.Stream") ; BinaryInputStream.Type = 1 ; // binary BinaryInputStream.Open ; BinaryInputStream.Write (ResponseBody) ; BinaryInputStream.Position = 0 ; var DataByte = BinaryInputStream.Read (1) ; Response.Write (typeof (DataByte)) ; // displays "unknown" How do I get the byte value of the byte I have just read from the stream? Asc () and byte () don't work (JScript) TIA

• ListView in ArrayAdapter order get's mixed up when scrolling

  - by Dan B

  Hi, I have a ListView in a custom ArrayAdapter that displays an icon ImageView and a TextView in each row. When I make the list long enough to let you scroll through it, the order starts out right, but when I start to scroll down, some of the earlier entries start re-appearing. If I scroll back up, the old order changes. Doing this repeatedly eventually causes the entire list order to be seemingly random. So scrolling the list is either causing the child order to change, or the drawing is not refreshing correctly. What could cause something like this to happen? I need the order the items are displayed to the user to be the same order they are added to the ArrayList, or at LEAST to remain in one static order. If I need to provide more detailed information, please let me know. Any help is appreciated. Thanks.

• MS Access 2003 - Formatting results in a list box problem.

  - by Justin

  So I have a list box that displays averages in a table like format from a crossyab query. It's just what I need the query is right, there is just one thing. I had to set the field properties in the query as format: standard..decimal:2. Which is exactly what I needed. However..the list box will not pick up on this. First I typed the crosstab sql into the list box's properties....and then I ran into this problem. So then I actually just created the query object, saved it and set that as the rowsource for the list box. Still won't work....when I open the query it is the correct format. So is there a way to further format a text box? Is there a way tell it to limit decimal places to one or two on returned values? Thanks!

• Unsigned long with negative value

  - by egiakoum1984

  Please see the simple code below: #include <iostream> #include <stdlib.h> using namespace std; int main(void) { unsigned long currentTrafficTypeValueDec; long input; input=63; currentTrafficTypeValueDec = (unsigned long) 1LL << input; cout << currentTrafficTypeValueDec << endl; printf("%u \n", currentTrafficTypeValueDec); printf("%ld \n", currentTrafficTypeValueDec); return 0; } Why printf() displays the currentTrafficTypeValueDec (unsigned long) with negative value? The output is: 9223372036854775808 0 -9223372036854775808

• Boolean issues in PHP

  - by McNabbToSkins

  I have a question regarding bools in php. I have a stored mysql proc that is returning a boolean. When this value is grabbed on the php side it displays the value as being a 0 or 1. This all seems fine to me and I have read in the php manual that php will interpret a 0 or 1 as false or true at compile time but this does not seem to be the case to me. I have gone a step further and casted my returned value with (bool) but this still does not seem to work. My if statements are not properly firing because of this. Does anyone know what is going on? Thanks for the help.

• Grouping data in an NSMutable array

  - by padatronic

  Hi guys, I have an array i load with lots of data from an xml file. I am displaying this on a tableview and then when you click on say an author it goes through to display all their books. At the minute my NSMutableArray has an entry for every each book with title, author and so on. So in the table of authors it display the authors name as many times as they have books. I want to group the array data so the table only displays each author once but the author contains an array of his books. Seems simple but I can't find a group method for arrays. thanks peeps

• Can you decode a mutable Bitmap from an InputStream?

  - by Daniel Lew

  Right now I've got an Android application that: Downloads an image. Does some pre-processing to that image. Displays the image. The dilemma is that I would like this process to use less memory, so that I can afford to download a higher-resolution image. However, when I download the image now, I use BitmapFactory.decodeStream(), which has the unfortunate side effect of returning an immutable Bitmap. As a result, I'm having to create a copy of the Bitmap before I can start operating on it, which means I have to have 2x the size of the Bitmap's memory allocated (at least for a brief period of time; once the copy is complete I can recycle the original). Is there a way to decode an InputStream into a mutable Bitmap?

• UIActionSheet With PickerView not showing up in iPad

  - by user717452

  I am using the following code to add an actionsheet with a picker view on it to my app. From the iPhone, it displays perfectly, but when viewing on iPad (Universal app), it shows a very small pickerview with none of the other buttons right on the center of the page. UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Select Chapter" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Select" otherButtonTitles:nil]; // Add the picker UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0,185,0,0)]; pickerView.delegate = self; pickerView.showsSelectionIndicator = YES; // note this is default to NO [menu addSubview:pickerView]; [menu showFromTabBar:self.tabBarController.tabBar]; [menu setBounds:CGRectMake(0,0,320, 700)]; [pickerView release]; [menu release];

• Views jump during ViewDidLoad

  - by Jon-Paul

  Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

• Recommendations for an in memory database vs thread safe data structures

  - by yx

  TLDR: What are the pros/cons of using an in-memory database vs locks and concurrent data structures? I am currently working on an application that has many (possibly remote) displays that collect live data from multiple data sources and renders them on screen in real time. One of the other developers have suggested the use of an in memory database instead of doing it the standard way our other systems behaves, which is to use concurrent hashmaps, queues, arrays, and other objects to store the graphical objects and handling them safely with locks if necessary. His argument is that the DB will lessen the need to worry about concurrency since it will handle read/write locks automatically, and also the DB will offer an easier way to structure the data into as many tables as we need instead of having create hashmaps of hashmaps of lists, etc and keeping track of it all. I do not have much DB experience myself so I am asking fellow SO users what experiences they have had and what are the pros & cons of inserting the DB into the system?

• Possible to use a .dll on Linux

  - by random_hero

  Question: Is it possible to compile a program on linux using a .dll file? Where this is going: This .dll will be used to write a php extension to some proprietary software from a third party. Background and Research: I have been given a library called proprietary.lib. I was curious, as I have never seen the .lib extension before, so I typed: file proprietary.lib The output was: proprietary.lib: current ar archive I did some research and found that ar is more-or-less tar (and in fact, I guess tar has since replaced ar in most *nix environments). Upon inspecting the ar manpage, I saw the t option, which displays a table listing of the contents of that archive. Cool. So I type: ar t proprietary.lib And get: proprietary.dll proprietary.dll ... (snip X lines) ...

• Reducing decimal places in Delphi

  - by Hendriksen123

  I am storing a list of numbers (as Double) in a text file, then reading them out again. When I read them out of the text file however, the numbers are placed into the text box as 1.59993499 for example, instead of 1.6. AssignFile(Pipe, 'EconomicData.data'); Reset(Pipe); For i := 1 to 15 Do ReadLn(Pipe, SavedValue[i]); CloseFile(Pipe); Edit1.Text := FloatToStr(SavedValue[1]); The text in Edit1.text, from the code above, would be 1.59999... instead of the 1.6 in the text file. How can i make it so the text box displays the original value (1.6)?

• Webwork actions, the lifecycle of variables declared in the action class.

  - by Sam

  Hi all, I'm using the webwork framework (JIRA plugin development) and was wondering about the lifecycle of the variables in the action class. I have a few private variables in the action class that are set when during the doDefault() method. These are used in the input view to set up jqGrid columns and then when the user has entered some data they click submit which puts the grid data into a hidden input. The next thing that happens is the doValidation() method is called before the doExecute(), which displays the input view if there are any errors. The problem is that the variables set up in the doDefault() method are now null. Can anyone explain to me how the lifecycle of variables works in the webwork actions? Cheers

• What if I have an API method and a contoller/view method with the same name in RoR?

  - by Chad Johnson

  Suppose I want to be able to view a list of products on my site by going to /product/list. Great. So this uses my 'list' view and outputs some HTML which my web browser will render. But now suppose I want to provide a REST API to my client where they can get a list of their products. So I suppose I'd have them authenticate with oAuth and then they'd call /product/list which would return a JSON array of their products. But like I said earlier, /product/list displays an HTML web page. So, I have a conflict. What is normal practice as far as providing APIs in Rails? Should I have a subdirectory, 'api', in /app/controller, and another 'product' controller? So my client would go to /api/product/list to get a list of their products? I'm a bit new to RoR, so I don't have the best grasp of the REST functionality yet, but hopefully my question makes sense.

• Weird background offset of UIToolbar when in formSheet.

  - by Mike A

  As you can see in the pic, the buttons from the toolbar on the right align perfectly with the segmented control on the left. They are displayed on the navigation bar. For some reason though, the background of the toolbar seems to be offset 1px to the bottom. What is especially weird, is this exact same view controller, in fullScreen or even pageSheet, displays everything properly. Segmented control is being allocated: UISegmentedControl* segmentControl = [[UISegmentedControl alloc] initWithFrame:CGRectMake(0,0,300,30)]; Toolbar is being allocated: UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100,44)]; I've spent hours trying to fix this, it's driving me crazy.

• Jquery roller/toggle effect

  - by Paul Higgins

  Hi, I'm looking for a "roller toggle" in jquery (ideally using a plugin). If I have the following HTML: <ul> <li>Option 1</li> <li>Option 2</li> <li>Option 3</li> </ul> I would like the first option to be displayed and the others hidden. Each time I "tap/click" on an option it displays the next and loops around to the first one after the last one. When used on a mobile web device I'd like it respond to swipe up/down events and appear like a "roller" (i.e. using a slide up/down effect). Too much to ask? Hopefully not, any pointers appreciated. Thanks, Paul

• ToolStripComboBox + objects default string value

  - by Martin

  I am using a ToolStripComboBox to list some data. I am populating this combo with some custom objects: For Each obj As myObject In myObjectList myToolStripComboBox.Items.Add(obj) Next This works great except the text displayed in the combo is the name of the object class. I can understand why and realise that I need to do something to make the combo use a property from my class instead. The help files state: To add objects to the list at run time, assign an array of object references with the AddRange method. The list then displays the default string value for each object. You can add individual objects with the Add method. The bit in bold suggests I need to setup the default string value in my class. How would I go about doing this?

• Automate open dialog in C#? (From COM OCX)

  - by JL

  I have a COM OCX control that I need to automate. It has a method called Open() this method is called without parameters, and always displays an open file dialog (standard one with windows). Is there a way for me to somehow get the file open dialog to open a file I specify , then close the dialog? I would also not like to use sendkeys or any other variants, because I require the solution to be reliable. So ideally would like to grab a handle on that window, and set the file name programatically, and then execute the open method programatically. Thanks in advance.

• Silverlight Scrollable Content Problem

  - by Steve

  I am fairy new to Silverlight and I have a problem. I have a grid on a page that is resizable when the user resizes their browser window. In one of the grids columns I want to display dynamically added content that is scrollable, as there is more data than space available. I currently have a scrollViewer with a stack panel inside it, that i programmatically add a user control to and then several user controls to that control depending on the amount of content. My problem is this. The scrollViewer does not respect the available space and as such displays its content outside of the viewable area when there is more data than space. i.e. it does not uses it is not scrollable nature. Hopefully this is something simple that I have missed, but i am banging my head against the wall at the moment. Any help gratefully received.

• Display message when user leaves site

  - by Brian Rasmusson

  Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

• Delphi component or library to display mathematical expressions

  - by Svein Bringsli

  I'm looking for a simple component that displays mathematical expressions in Delphi. When I started out I thought it would be easy to find something on the net, but it turns out it was harder than anticipated. There are lots and lots of components that will parse mathematical expressions, but few (none?) that will display them. Ideally I would like a component as simple as a TLabel, where I could set the caption to some expression and it would be displayed correctly, but some sort of library that let's me draw expressions to a canvas would also be sufficient for my needs. Update: I'm not talking about plotting graphs of functions or something like that. I want to display (for instance) (X^2+3)/X like this:
