  • How can I overlay one image onto another?

    - by Edward Tanguay
    I would like to display an image composed of two images. I want image rectangle.png to show with image sticker.png on top of it with its left-hand corner at pixel 10, 10. Here is as far as I got, but how do I combine the images? Image image = new Image(); image.Source = new BitmapImage(new Uri(@"c:\test\rectangle.png")); image.Stretch = Stretch.None; image.HorizontalAlignment = HorizontalAlignment.Left; Image imageSticker = new Image(); imageSticker.Source = new BitmapImage(new Uri(@"c:\test\sticker.png")); image.OverlayImage(imageSticker, 10, 10); //how to do this? TheContent.Content = image;

  • Why does Ubuntu gets stuck on the loading screen?

    - by mohit
    I've been experiencing many problem lately since I fresh installed Ubuntu 12.04 LTS on my SONY VAIO VPCEH with Windows 7 previously installed. Sometimes when I try to boot Ubuntu, it gets stuck at loading screen. There seems to be some problem with driver (as far I can judge). Following is the log generated, when I press Esc during the boot (before the problem occurs): ... * Stopping System V initialization compatibility [ok] * Starting System V runlevel compatibility [ok] * Starting crash report submission daemon [ok] * Starting automatic crash report generation [ok] ... ... * Starting LightDM Display Manager [ok] Nothing works after that, no Esc, etc, except restart. Also I've observed the following: Inactivity of Hard-drive (Led doesn't glows). Flashing, or blinking, of Caps-lock and Scroll-lock On restart, Ubuntu seem to load successfully. However, the loading screen has somewhat basic graphics. This problem started after I installed Additional drivers: NVIDIA accelerated graphics driver Also, most of the times Ubuntu loads without any problem. However, it is annoying to restart everytime it fails. So my question is: Why this happens and what is the solution?

  • Combining iPhone/iPad apps into one universal app

    - by user324881
    I have two apps (one for the iPhone, the other for the iPad) that I'd like to combine into one universal app. For my first attempt, I tried creating a new universal app project and added the libraries for the iPhone and iPad versions. The iPad version compiled and ran fine (as expected), but the iPhone version didn't. My hope was that I could create a universal app that would execute only the project in the iPhone library when running on the iPhone and vice versa for the iPad. It seems like this should still work. Is there a way to tell the universal app project to ignore one of the external libraries when compiling for the iPad and vice versa for the iPhone? Thanks!

  • MySQL: Count two things in one query?

    - by Nebs
    I have a "boolean" column in one of my tables (value is either 0 or 1). I need to get two counts: The number of rows that have the boolean set to 0 and the number of rows that have it set to 1. Currently I have two queries: One to count the 1's and the other to count the 0's. Is MySQL traversing the entire table when counting rows with a WHERE condition? I'm wondering if there's a single query that would allow two counters based on different conditions? Or is there a way to get the total count along side the WHERE conditioned count? This would be enough as I'd only have to subtract one count from the other (due to the boolean nature of the column). There are no NULL values. Thanks.

  • Writing datatable to database file, one record at a time

    - by Kevin
    I want to write a C# program that will read a row from a datatable (named loadDT) and update a database file (named Forecasts.mdb). My datatable looks like this (each day's value is a number representing kilowatts usage forecast): Hour Day1 Day2 Day3 Day4 Day5 Day6 Day7 1 519 520 524 498 501 476 451 My database file looks like this: Day Hour KWForecast 1 1 519 2 1 520 3 1 524 ... and so on. Basically, I want to be able to read one row from the datatable, and then extrapolate that out to my database file, one record at a time. Each row from the datatable will result in seven records written to the database file. Any ideas on how to go about this? I can connect to my database, the connection string works, and I can update and delete from the database. I just can't wrap my head around how to do this one record at a time.

  • Two tables side by side in one column LaTeX environment

    - by Gacek
    The question is similar to this one: http://stackoverflow.com/questions/1491717/how-to-display-a-content-in-two-column-layout-in-latex but about placing two tables side by side. I have two small tables looking like that: \begin{table}[t] \begin{tabular}{|c|l||r|r||r|r|} %content goes here \end{tabular} \caption{some caption} \end{table} \begin{table}[t] \begin{tabular}{|c|l||r|r||r|r|} %content goes here \end{tabular} \caption{some caption for second table} \end{table} I have one-column document and these tables are really narrow, so I would like to display them side by side (with separate captions) insted of one under another with a lot of unused, white space. I tried to do it with this \multicols but it seems that floats (tables here) cannot be placed inside of it. Any ideas?

  • Macro to copy data from one sheet to another based on the current date

    - by SgtSnafu
    Does anyone have a macro that copy data from one sheet to another based on the current date? I am working with a single workbook of three sheets. Sheet one will hold the manual input of daily production figures for multiple plants, sheet two is to hold ongoing daily data, keyed on sheet one. The macro will be associated with a button, so that once clicked it would search for every row that has a date of today, and copy that row to the next available blank row on sheet two. Sample Data... Plant 1 Input Date - $ Produced - Labor Hour 3-29-10 - 4538 - 8 3-30-10 - 7862 - 12 3-31-10 4-1-10 4-2-10 Plant 2 Input Date - $ Produced - Labor Hour 3-29-10 - 4545 - 9 3-30-10 - 7645 - 12 3-31-10 4-1-10 4-2-10

    Right now, there seems to be no such effect.

  • VWD Express won't let me add one table!

    - by user530809
    Sorry if this question is too trivial but I really haven't found any related questions and I am shaking too much to think logically. I spent like few hours waiting for SQL Server to finally install (you know, it's Microsoft) and now when I want to add new table to database it says "this feature is not supported by Microsoft Visual Web Developer Express". How could this happen? I mean, what's the point of even letting me use this if I can't even add one table to database, and I won't even know about it until I actually need to do it? Are they really serious or is it just some mistake? Is there any way to get around this problem? I need to create just one simple project with one small table in database but it won't let me, but I can't believe they could actually have nerves to make express edition without such a trivial function, so maybe I just made something wrong and there's actually some way to add this table? Sorry for being so whiny but I'm just fed up with this environment.

  • one site or many?

    - by Alex
    I have about 10-12 websites (main site is classic ASP, others are ASP.NET 2). Each site has his own virtual directory. They are related to each other, mainly from main site other sites are calling to perform some service. Each site has from 2 to 5 pages. Does it make sense to unite them and create one bigger site with one virtual directory and one project in VS? Or leave them as they are separately? What are pro and contras?

  • Problem with an application on USB, a tricky one

    - by rajivpradeep
    I have this application on USB built in VS 2008, on win7 , the USb has two partitions one hidden and other normal one, when i run the application on normal part , it has to swap the part to hidden and run the applications present in hidden part. When i run the application in normal part from USB , the memory swaps but the applications in hidden part are not run. but i can see the application running in Task manager. when i copy the application and run it from the desktop, the application works seamlessly, without any glitch. I guess some thing is holding the application process when run from USB, i cannot safe eject the USB too. CAn some one give me a clue as to what can be done to resolve. Also the application works well on Windows 7 as expected. The problem is on XP

  • Android Paypal One time Payment

    - by Ameya
    Hi All, Does any one know, or is it possible to do one time payment, with paypal in android ? Consider the senario. Buyer purchases installs free application. Clicks on paypal module and makes in-app payment, purchases feature successfully. Buyer deletes application. All information including the feature purchase enty in database is deleted. Buyer reinstalls the application. Here is the catch, if he wants to use the feature he will have to do a re-purchase. Which I wann to avoid in my application. This is taken care in iPhoen in-app purchase. That is if a buyer has already purchased an feture or in-app item, and if he trys to repurchase it (item has been set to one time payment) , the in-app purchase transaction will succeed without the user actually having to repay for the item. Is there an solution for this can anyone help.

  • Multiple ASP.Net Controls On One Page

    - by Duracell
    We have created a User Control for ASP.Net. At any one time, a user's profile page could contain between one and infinity of these controls. The Control.ascx file contains quite a bit of javascript. When the control is rendered by .Net to HTML, you notice that it prints the javascript for each control. This was expected. I'd like to reduce the amount of HTML output by the server to increase page load times. Normally, you could just move the javascript to an external file and then you only need one extra HTTP request which will serve for all controls. But what about instances in the javascript where we have something like document.getElementById('<%= txtTextBox.ClientID %'); How would the javascript know which user control work with? Has anyone done something like this, or is the solution staring me in the face?

  • One big call vs. multiple smaller TSQL calls

    - by BrokeMyLegBiking
    I have a ADO.NET/TSQL performance question. We have two options in our application: 1) One big database call with multiple result sets, then in code step through each result set and populate my objects. This results in one round trip to the database. 2) Multiple small database calls. There is much more code reuse with Option 2 which is an advantage of that option. But I would like to get some input on what the performance cost is. Are two small round trips twice as slow as one big round trip to the database, or is it just a small, say 10% performance loss? We are using C# 3.5 and Sql Server 2008 with stored procedures and ADO.NET.

  • SQL - Joining multiple records to one record

    - by ho
    I've got a SQL Server database with the the following tables: Client (ClientID, ClientName) SalesAgent (AgentID, AgentName) Item (ItemID, Description) Purchase (PurchaseID, ClientID, Price) PurchaseSalesAgent (PurchaseID, AgentID) Each purchase is only ever one item to one client but there can have been multiple agents involved. I want to return the following list of columns: ClientName, Description, Price, Agents Where Agents is the names of all the agents involved in the purchase. Either as a comma separated list or as multiple columns with one agent in each. I'm looking for a way that's compatible with SQL Server 2000 but I'd also be interested in if there's a better way of doing it in SQL Server 2008.

  • How does one SELECT block another?

    - by Krip
    I'm looking at output of SP_WhoIsActive on SQL Server 2005, and it's telling me one session is blocking another - fine. However they both are running a SELECT. How does one SELECT block another? Shouldn't they both be acquiring shared locks (which are compatible with one another)? Some more details: Neither session has an open transaction count - so they are stand-alone. The queries join a view with a table. They are complex queries which join lots of tables and results in 10,000 or so reads. Any insight much appreciated.

  • Update Manager got stuck (but not frozen) while installing downloaded updates. What should I do?

    - by WarriorIng64
    I have just gotten my Ubuntu 12.04 LTS desktop computer reassembled after a trip back home and connected it to my parent's wireless Internet connection. The connection seems quite shaky (disconnects half the time, likely an ongoing issue with the wireless card I have installed), and it struggled to download updates because of the constant interruptions. Eventually, it managed to download the updated packages and started installing them. I got up and left it to do its work. When I came back, I saw it was still having trouble staying connected to the wireless (no surprise there), but then I noticed that it seemed like Update Manager had stopped making progress on the installation. I opened the Details pane to see what it was last doing: My guess was that the installation script for flashplugin-installer couldn't complete the download until I stabilized the Internet connection. I hooked my Ubuntu laptop up to my desktop via Ethernet and shared its wireless connection using this guide, and as I am typing this now from my desktop you can see that the connection issue was successfully worked around. However, even with a stable connection established, Update Manager seems "stuck" at its current position and won't go any further. It's not totally frozen, but I can't do anything beyond open/close the Details pane as the Cancel button is grayed out. I know it can cause big problems if updates are stopped during installation, but I'm at a loss as to how this situation should be handled. I'm sure it should finish normally if I can just find a way to restart Update Manager, but the question is how this should be approached. How can I safely get my updates to finish installing?

  • Return popupmenu selection in MATLAB using one line of code

    - by Doresoom
    I have a GUI which uses a selection from a popupmenu in another callback. Is there a way to return the selected value of the popupmenu in only one line without creating any temporary variables? I've tried several solutions, but I've only managed two lines with one temporary variable: Three lines: list=get(handles.popupmenu1,'String'); val=get(handles.popupmenu1,'Value'); str=list{val}; Two lines: temp=get(handles.popupmenu1,{'String','Value'}); str=temp{1}{temp{2}}; Can anyone shave it down to one? PS, It's a dynamic menu, so I can't just use get(handles.popupmenu1,'Value') and ignore the string component altogether.)

  • Horizontally Flip a One Bit Bitmap Line

    - by roygbiv
    I'm looking for an algorithm to flip a 1 Bit Bitmap line horizontally. Remember these lines are DWORD aligned! I'm currently unencoding an RLE stream to an 8 bit-per-pixel buffer, then re-encoding to a 1 bit line, however, I would like to try and keep it all in the 1 bit space in an effort to increase its speed. Profiling indicates this portion of the program to be relatively slow compared to the rest. Example line (Before Flip): FF FF FF FF 77 AE F0 00 Example line (After Flip): F7 5E EF FF FF FF F0 00

  • Managing multiple blogs (wordpress) from one control panel

    - by thisMayhem
    This is the deal: I have more than one blog (not running yet) that I want to install in subfolders for one of my domains. Each blog will obviously have its own look and feel and content. I could just have a set of control panels and administer them individually or I could somehow manage them form a single control panel. Issues I've come across are: Some plugins offer this functionality while suppressing other features like auto draf saving, in-post category and tag creation, image upload etc. I'm not necessarily looking for a ready solution, more like some guidance on how to approach this particular problem in the best possible manner. I'm looking for a fully working scenario, not some plugin that allows me to more or less simulate the one-blog-administration experience.

  • Active MQ showing more than one (ghost) consumer

    - by Shoey
    We have a system that uses ActiveMQ (Queues) - and have exactly one producer and one consumer (implemented as a Windows Service in .NET). Over the weekend, the infrastructure team had a reboot of the servers on the network, and from then on we noticed that there are more than one ghost consumer appearing that listens to the queue and we also suspect reads and deletes the messages. My questions are: is there any way from the Active MQ management console to find out what the consumers are (hostnames, etc). and Are there any scenarios in which inadvertent consumers get 'created'? For instance, there were suggestions about the active MQ journal folders getting corrupted after a reboot, or there is another suggestion that another machine with Active MQ broker automatically makes itself a consumer of all the queues on the main/live active mq server.

  • Query to get row from one table, else random row from another

    - by Jimmy
    tblUserProfile - I have a table which holds all the Profile Info (too many fields) tblMonthlyProfiles - Another table which has just the ProfileID in it (the idea is that this table holds 2 profileids which sometimes become monthly profiles (on selection)) Now when I need to show monthly profiles, I simply do a select from this tblMonthlyProfiles and Join with tblUserProfile to get all valid info. If there are no rows in tblMonthlyProfile, then monthly profile section is not displayed. Now the requirement is to ALWAYS show Monthly Profiles. If there are no rows in monthlyProfiles, it should pick up 2 random profiles from tblUserProfile. If there is only one row in monthlyProfiles, it should pick up only one random row from tblUserProfile. What is the best way to do all this in one single query ? I thought something like this select top 2 * from tblUserProfile P LEFT OUTER JOIN tblMonthlyProfiles M on M.profileid = P.profileid ORder by NEWID() But this always gives me 2 random rows from tblProfile. How can I solve this ?
