copy

问题 Lets say I got two images in VB.NET. Both are 100x100. Then I want to copy a section of the first image and paste it on the second image. For example, lets say I want to pickup the rectangle (25,25,75,75) from the first image, and paste it at (25,25) point of the second image. Sorry, it is hard to explain, so here's an example image: 回答1: This looks like what you are looking for. http://www.vb-helper.com/howto_net_drawimage_copy_part.html 来源： https://stackoverflow.com/questions/4811100/copy-a

问题 In Google Chrome you can retrieve the text of a JavaScript alert/dialog by simply having the dialog open and doing CTRL-C on the dialog. This will put the text in the dialog into the clipboard. I'm trying to use SendMessage to send CTRL-C to perform a copy on the text of a JavaScript dialog. I've already managed to do this using SendInput but unfortunately that could fail if the window doesn't have focus. I have tried using SendMessage with WM_COPY message but that didn't work for my needs.

问题 Is there any way or script to copy layer to all artboards in Photoshop? Thank you in advance, because I could not find a solution 回答1: Artboards are just specialized layer groups, which can be targeted with the document.layerSets property. In this working example (tested and working in Adobe PS CC 2019), I make the assumption that there is 1 layer we are copying and each artboard has 1 layer already in it.

问题 So I've been fussing with the Microsoft Support answer to this question but their code is simply not working. I'm confused about how they do not define x, or maybe x always equals a variable in VBA? Anyway, I am trying to copy all named ranges in one workbook and bring them over to another workbook. I have to do this for 50-odd workbooks and there are 30-40 named ranges in the base workbook. I really do not want to have to copy-paste these buggers manually. Here's the code they gave for this

问题 I have created a Python class with an attribute that is a Swig object (which happens to be a wrapper of a C structure). I want to be able to create copies of that class, e.g., by defining a __copy__ method, that contain independent copies of the Swig object (using the copy modules' copy class just creates a pointer to the original object, and deepcopy fails). Does anyone know if you can just copy chunks of memory in Python, and use this to copy the attribute containing the Swig object? Or,

问题 i've tried to find a solution to my problem using google but failed. there were a lot of snippets that didn't fit my case exactly, although i would think that it's a pretty standard situation. I'll have to transfer several different data arrays to cuda. all of them being simple struct arrays with dynamic size. since i don't want to put everything into the cuda kernel call, i thought, that __device__ variables should be exactly what i need. this is how i tried to copy my host data to the _

问题 All I want to do is copy a worksheet from an excel workbook to another excel workbook in Python. I want to maintain all formatting (coloured cells, tables etc.) I have a number of excel files and I want to copy the first sheet from all of them into one workbook. I also want to be able to update the main workbook if changes are made to any of the individual workbooks. It's a code block that will run every few hours and update the master spreadsheet. I've tried pandas, but it doesn't maintain

问题 I was trying to import a CSV file into a PostgreSQL table using the COPY command. The delimiter of the CSV file is comma (,). However, there's also a text field with a comma in the value.
