问题 I am using Rotativa to generate a pdf of my view. on my local computer this works. On my online server, it says cannot locate file or directory. It is probably a permission problem. Any idea how to fix it? Thanx in advance 回答1: Rotativa uses wkhtmltopdf at its' core, which starting from >0.12.0.0 relies on distributable VC++ lib (msvcp120.dll) You may need to download the installer from here rather than just copy dll over to the server http://wkhtmltopdf.org/downloads.html Simple test if

问题 I'm wondering if its possible to write a javascript program and have it compiled and linked into an executable? If so would it be possible to create a libjs that would be the equivalent of libc for the c/c++ world? wouldn't creating something like this make javascript a full fledged language that could then be compiled and run directly on the target hardware? If you had a compiler for javascript, couldn't you write a new compiler in javascript? 回答1: Yes, you could write a js compiler. Not

问题 I am trying to launch a PuTTY window that establishes a serial connection, and then have the main cmd window (the one that launched my Python script) control the PuTTY window. The PuTTY window will still be open and showing everything, but I want to disable the stdin on it and just have it get the input from the cmd shell. So I have it successfully launching the PuTTY window, just cant seem to pipe my outputs and inputs like I want. Any help would be greatly appreciated! Code for launching

问题 I would like to wait until a for loop is finished to continue with my function. I can't seem to get it to work. Hello is always logged before the for loop finishes. Why is this, and what would be a way to run only when the for loop has finished. I need to wait for the for loop to finish before continuing within the function, but outside the for loop. I want to know how to wait until a for loop is finished, and then execute code. Not set timeouts within the for loop. function doMergeAnimations

问题 I am using this to determine if Office is 32-bit or 64-bit. I am calling it from a C# app. GetBinaryType(location, out bt) The exact same code, calling this on winword.exe, returns either 32-bit or 64-bit, matching the bitness of my C# app. Is there something I need to do when running in 64-bit mode that it still returns 32-bit for Office? I've put a very simple sample program here. The output running in x86 mode (on 64-bit Windows is): Running in 32-bit mode. GetBinaryType() returns SCS

问题 I run automation that installs a preset OS /w Drivers and configuration. I inherited the automation second hand and there's a lot to it. I have a system with hybrid graphics and it hands on verifying the display drivers. Now, I can walk over to the machine, open device manager, right click on one of the graphics devices, click uninstall (i do not delete the driver files) and then the automation continues. Once its done, the system restarts and both device drivers are back. I am wondering if

问题 I am developing a Spring Batch App - How to understand or write code for ? Identify which chunk has failed in chunk based step? How to identify if reader query taking how much time? 回答1: Identify which chunk has failed in chunk based step? A ChunkListener allows you to achieve that.

ItemReadListener is called around each read operation

问题 Good afternoon I have selected stackoverflow for this question because probably mainly programmers are confronted with this question: This is the issue: If we call Get-AzADUser to get all AAD Users in the Azure Automation Runbook, then we get: Error 'Insufficient privileges' We do it like this: We have an Automation Account with an "Azure Run As Account" In the PowerShell Runbook we call: # Connect to AAD $Conn = Get-AutomationConnection -Name AzureRunAsConnection $account = Connect-AzAccount

问题 I have a bit question i couldnt solve. I wanna implement CNN model with fully-connected MLP to my protein database which has 2589 proteins. Each protein has 1287 rows and 69 columns as input and and 1287 rows and 8 columns as output. Actually there was 1287x1 output, but i used one hot encoding for class labels to use crossentropy loss in my model. Also i want if we consider as image i have an 3d matrix ** X_train = (2589, 1287, 69) for input** and y_train =(2589, 1287, 8) output , i mean

问题 I need to implement following behavior: when server starts, it should check for existing servers using broadcast. Then it waits for answer. But, how to set any timeout for waiting? int optval = 1; char buff[BUFF_SIZE]; SOCKADDR_IN addr; int length = sizeof(addr); if (setsockopt(s, SOL_SOCKET, SO_BROADCAST, (char*)&optval, sizeof(optval)) == SOCKET_ERROR) throw(errors::SETSOCKOPT); addr->sin_family = AF_INET; addr->sin_port = htons(this->serverPort); addr->sin_addr.s_addr = INADDR_ANY; sendto
