"CONVERT not working for VARCHAR to DATETIME",
"I've tried everything I can find (CAST, CONVERT, converting on import, checking default language settings) but I cannot find a working solution to convert my VARCHAR values to DATETIME. I'd like to insert a conversion of this field into a new table where that column is set up as DATETIME. \n\nWhen I run: \n\nSELECT CONVERT(VARCHAR, [first air date], 121) \nFROM mytable\n\n\nthe results are returned fine and error free. However, when I run:\n\nINSERT INTO newtable\n SELECT ID, column1, column2, \n CONVERT(VARCHAR, [first air date], 121) \n FROM mytable\n\n\nI get this error:\n\n\n Msg 242, Level 16, State 3, Line 1\n The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. The statement has been terminated.\n\n\nWhy am I getting results (as in the first query) but it won't insert them into another table?\n\nThe data looks like this: '2004-02-23 00:00:00.000' (I know the dashes aren't best practice but I have no wiggle room on that because this format has been determined by other colleagues).\n\nI'm importing the data via .csv and this column is set as date format in Excel.\n\nCorrection\nI now realise it should be CONVERT(DATETIME, [first air date], 121). However, this does not solve the actual problem at hand, which is converting to DATETIME from VARCHAR without the 'out of range' error."

"How can I prevent external MSBuild files from being cached (by Visual Studio) during a project build?",
"I have a project in my solution which started life as a C# library project. It's got nothing of any interest in it in terms of code, it is merely used as a dependency in the other projects in my solution in order to ensure that it is built first. One of the side-effects of building this project is that a shared AssemblyInfo.cs is created which contains the version number in use by the other projects.\n\nI have done this by adding the following to the .csproj file:\n\n<ItemGroup>\n <None Include=\"Properties\\AssemblyInfo.Shared.cs.in\" />\n <Compile Include=\"Properties\\AssemblyInfo.Shared.cs\" />\n <None Include=\"VersionInfo.targets\" />\n</ItemGroup>\n<Import Project=\"$(ProjectDir)VersionInfo.targets\" />\n<Target Name=\"BeforeBuild\" DependsOnTargets=\"UpdateSharedAssemblyInfo\" />\n\n\nThe referenced file, VersionInfo.targets, contains the following:\n\n<Project ToolsVersion=\"4.0\" DefaultTargets=\"Build\" xmlns=\"http://schemas.microsoft.com/developer/msbuild/2003\">\n <PropertyGroup>\n <!--\n Some properties defining tool locations and the name of the\n AssemblyInfo.Shared.cs.in file etc.\n -->\n </PropertyGroup>\n <Target Name=\"UpdateSharedAssemblyInfo\">\n <!--\n Uses the Exec task to run one of the tools to generate\n AssemblyInfo.Shared.cs based on the location of AssemblyInfo.Shared.cs.in\n and some of the other properties.\n -->\n </Target>\n</Project>\n\n\nThe contents of the VersionInfo.targets file could simply be embedded within the .csproj file but it is external because I am trying to turn all of this into a project template. I want the users of the template to be able to add the new project to the solution, edit the VersionInfo.targets file, and run the build.\n\nThe problem is that modifying and saving the VersionInfo.targets file and rebuilding the solution has no effect - the project file uses the values from the .targets file as they were when the project was opened. Even unloading and reloading the project has no effect. In order to get the new values, I need to close Visual Studio and reopen it (or reload the solution).\n\nHow can I set this up so that the configuration is external to the .csproj file and not cached between builds?"

"SPI fails to read first 6 bytes",
"I'm having a lot of issues with SPI module on my STM32F051 MCU. I've got it configured as a master to drive a slave flash memory module (that doesn't really matter).\n\nI'm trying to read 8 bytes from memory, this is how the 'read data' message is structured:\n\nFirst 4 bytes of the message are transmitted, next 8 are received.\nFirst byte is 'read data' opcode, three following are data address and equal 0 in this case.\n\nCode:\n\nmemset(out, 0x00, 256);\nmemset(in, 0x00, 256);\nout[0] = OPCODE_READ;\nout[1] = 0x00;\nout[2] = 0x00;\nout[3] = 0x00;\nuint32_t len = 4 + size; // size == 8\n\nspi_select(M25P80);\nHAL_SPI_TransmitReceive(&hspi1, out, in, len, TIMEOUT);\ndelay_ms(BYTE_SPEED_MS * 5); // Needed because ^ finishes before physically \n // transmitting the data. Nevermind the 5, it \n // was picked experimentally \nspi_deselect(M25P80);\n\n\nSignal (yellow - clock, red - miso):\n\n\n\nAt 488 bits/s transmitting 4 bytes takes 4 * 1E3 / (488 / 8) = 65.5 ms. Then the reception starts. Memory starts transmitting [0xFF...0xFF] right away, but contents of the 'in' buffer are:\n\n[0x00 0x00 0x00 0x00] [0x00 0x00 0x00 0x00 0x00] 0xFF 0xFF 0x00...0x00\n^ zero because this ^ should be 0xFF ^ correct data\n is the part where\n data was being sent\n to the memory\n\n\nSo first six bytes of data are just lost. Am I the only one who's having such a hard time with STM's SPI module?\n\nEDIT:\n\nI've gotten myself a different eval board with a slightly different MCU (STM32F030) and it gets even weirder:\n\n[0x02 0x02 0x02 0x02] \n0x00 0x02 0x00 0x00 0xFF 0x00 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0x00...0x00\n\n\nAlthough I must mention that I'm using a different compiler with this MCU.\n\nEDIT 2:\n\nThe way I partially got it to work is using 16-bit mode with SPI. This fixed this particular bug, but there are more similar oddities with STM32's SPI.\n\nEDIT 3:\n\nSPI initialisation code:\n\nvoid MX_SPI1_Init(void)\n{\n\n hspi1.Instance = SPI1;\n hspi1.Init.Mode = SPI_MODE_MASTER;\n hspi1.Init.Direction = SPI_DIRECTION_2LINES;\n hspi1.Init.DataSize = SPI_DATASIZE_16BIT;\n hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;\n hspi1.Init.CLKPhase = SPI_PHASE_1EDGE;\n hspi1.Init.NSS = SPI_NSS_SOFT;\n hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_2;\n hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;\n hspi1.Init.TIMode = SPI_TIMODE_DISABLED;\n hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLED;\n hspi1.Init.NSSPMode = SPI_NSS_PULSE_DISABLED;\n HAL_SPI_Init(&hspi1);\n\n}"

Access method 1 works but Access method 2 doesn't when I try to build the comparison dataframe.\nAccess method 1:\nX_data = df_scores[['Hours']]\ny_data = df_scores['Scores']\nX_train, X_test, y_train, y_test = train_test_split(X_data, y_data, test_size=0.20, random_state=0)\nlm = LinearRegression()\nlm.fit(X_train, y_train)\ny_hat = lm.predict(X_test)\n\nThis dataframe works:\ndf_scores_comp = pd.DataFrame({'Actual':y_test, 'Predicted':y_hat})\ndf_scores_comp\n\nAccess method 2:\nBut if I want to use the following way to access X_data and y_data ...\nX_data = df_scores.loc[:, ['Hours']]\ny_data = df_scores.loc[:, ['Scores']]\n\nI get the following error ...\nIf using all scalar values, you must pass an index\n\nWhen using either access method, y_hat is an array and X_data is a dataframe. But y_data is a series using the first access method and a dataframe in the second access method. I thought the clue might be in there somewhere with lm.predict but I can't figure it out.\nWhen I tried the solution offered here (Constructing pandas dataframes...) by wrapping the dictionary in a list, I don't get an error. But the result isn't right: the y_hat (predicted) elements are in the correct column, but are squeezed into one row. And the y_test (Actual) elements and the index values are mixed up in the wrong columns and are squeezed into one row as well. Something like this:\n Actual Predicted\n0 Scores 5 20 2 27 19 69 16... [[16.884144762398048], [33.73226077948985], [7...\n\nIt should look like this (which is does using the first access method):\nActual Predicted\n5 20 16.884145\n2 27 33.732261\n19 69 75.357018\n16 30 26.794801\n11 62 60.491033"

"How to check within an app if the device is connected to a power supply?",
"I see many reasons why an app should behave different if the device is connected to a power supply, via USB cable ore otherwise.\nFor example, with power on and effectively charging, it could be used as an image viewer, which would be prohibitive if running on battery.\nSo, how to let an app check if power supply is on, and, if the battery is charging or still running low (due to other power consuming processes or perhaps just because it's old and leaking).\nEdit: in view of the comment that points to a method to get noticed of changes of power supply:\nThis is valuable, maybe for other applications, but I'm asking for actual power supply minus battery need for recharging."

"What are reasons for Durandal/Hot Towel template setting body max-width to 1100px when using Bootstrap fluid styles?",
"It's noticeable when using the \"Hot Towel\" SPA template with Durandal that the views sit in a middle window that's 1100 pixels in width rather than using all the available space.\n\nAnd yet all the views within the applicationHost are set to use the Bootstrap from Twitter \"fluid\" styles. Effectively a hard-coded max-width set on the body tag is making all these fluid styles redundant and rather meaningless.\n\nIt's easy enough to over-ride the body style set in app.css (assumming there will be no side effects to setting it to a ridiculously high value) but I was just wondering if anybody knew the reason for setting it this way in the template, given that it's undoing all the good work of trying to implement a responsive design that all those Bootstrap \"*-fluid\"styles are trying to implement."

"I made a JPanel and JSlider for zooming the JPanel in java .\n\nNow What my problem is zooming has to be done similar to the MS Office power point Slide Screen zooming\n\nThe JSlider is outside of the JScrollPane that holds the JPanel. As the JSlider is moved to the right, the JPanel expands in size. As the JSlider is moved to the left, the JPanel reduces in size. At any zoom size, the contents of the JPanel have to remain editable.\n\nI am little bit weak in using paint method or affine transform in Java.\n\nPlease help me."

"How can I make the CSS attribut of a Div to change when there is a text overflow on another Div?",
"I'm building a Div with column-count = 2, column-fill = auto, and a height = 100%.\n\nThis Div will contain some other Div with text inside.\nHowever, I want my page to be fluid and adapt automatically when the window get shorter in order that overflowing text could be read on the 2 columns by using the browser scrollbar.\n\nSo I need my Div to remove height = 100% and replace it with min-height = 100% in order that a scrollbar appear on the browser to allow to read below the overflowing text on 2 column instead of having the overflowing text appearing on third column (despite column-count = 2).\n\nIs there a way to achieve this with CSS only or should I need Javascript, and how ?\n\nMany Thanks"
