  1. Same trick can solve flickering of the cursors of a graph when the graph data is updated. However, it can result in seemingy unrelated errors, for example triggering an autoscale on an axis with property-node doesn't work the same way as without the transplarent overlay, so far as I remember. This is obviously just a simptom of some updating (order) thing. So if you have any "special" behaviour of your control/idicator, you better test everything (which is close to impossible), or try to recall this hack if something that once worked stops working as expected.
  2. Hi, Do you have specific examples of the data you want to process? How do you get zero pulse width? Do you want to ptocess the whole data or just a portion of it "real time"? If your data is that special, why don't you do the anlysis yourself? It's clear how you define pulse width of a rectangle, but how do you define it for a smoother data? If you always have special data (rectangular or triangluar), then I think your best bet is to calculate everything by yourself, or detect whether the data is special or normal "waveformable" data and handle the two kind separately. Also, have yo
  3. If I want to have lossless data for processing but also want to display data on the GUI then I simply have a processor loop with a queue and a display loop with notifier and the producer loop feeds both. This means copying some of the data, but usually the not the huge part of it that has to be processed. If the GUI state depends on processing the data, some GUI updates go into the data processor loop, so it's not an unstained arcitecture.... But I try to keep the number of GUI elements updated from the processor loop as low as possible, and also I try to use the terminals of the indicators in
  4. Note to codes: I'm am only a hobbyist tinker, and I don't know how nice LV code is written. And I hope I posted every relevant things. You don't have to care much about the "alive_clients" thing. It's there to make sure the reply buffer doesn't overflow if a client gets lost before the server' reply gets forwarded to the client by the webservice. The server program that reads the request queue and writes the reply buffer is too complicated to be useful. And to point out again: The client ip is sent by the client itself. Then you have to keep track of the ips in the server program log
  5. ImageMagick has command line interface so you can use "System Exec.vi". ImageMagick works with files (at least the command line thing). So you have to save the picture, call "System Exec.vi" with the proper command and parameters, this will make another file (or overwrite), then you have to load this file to Labview. For not high resolutions, this will probably fit the 0.5 second time (and based on the picture you posted, the resolution in pretty low). I have to ask the usual question though: what is your final goal? Maybe you could go the other way around and barrel-distort the whateve
  6. Some other constrains of my use case, so we can see if it's really similar to yours: a client always waits for a proper reply (be it success or error) before issuing other commands to the server a few dozens of clients at a time stable communication is much more important that speed, so it's accepteable for the client to wait even for fours for a "success" reply (in case the server restarts due to an update and the IT's asdfg...), but usually reply comes in a few seconds. writing is even rarer, since a client has to reserve the machine first (reservation is handled by
  7. I'm not sure I understand the problem correctly, but I had a seemingly similar situation. The clients send two request types: "write xyz" and "status?" The server side has two layers: a thin webservice: for "write" requests: queues the requests (write queue) with client ip and immediately responses with "acknowledged" for "status?" requests: immediately responses with the last message for that client from the reply buffer, or empty string if no replies for the client are available the main server program: sequentially write the e
  8. Hello, If it's okay to use 3rd party free tools, you could look into ImageMagick. It has command line interface. L.
  9. It can be solved with a fairly simple macro. Sub ReplaceTextWithImage(findText as string, imagePath As String) If Selection.Find.Execute(FindText:=findText, MatchWholeWord:=True, Forward:=True, Wrap:=wdFindContinue) = True Then Selection.InlineShapes.AddPicture FileName:=imagePath, LinkToFile:=False, SaveWithDocument:=True End If End Sub EDIT: added checking if text found and MatchWholeWord and continue search if out of selection range. Other checks should be added to the labview code (image file exists and findText not empty). Note, that the Selection.
  10. Hi all! How do you implement mouse capture for controls? This is more of a philosophical question about your solutions, you did you learn to live without it etc. By mouse capture I mean mouse capture: A control receives mouse events even if the pointer is not above the control. It's useful for dragging among controls, or for a graphical user interface (mousedown>mousemove>mouseup event chain). Without mouse capture if the user accidentally leaves the drawing area during a drag-like operation and mouseup occurs outside, the drawing area gets stuck in dragging mode (mostly). Th
  11. Hi all, I'm trying to insert images at specific texts in a Word document with the Report Generation Toolkit. Kind of like search and replace, but with an image as replacement. All I found that inserting a picture can be either done at bookmarks or into table cells. I want to avoid Bookmarks because it's easier to add some hashtags than editing bookmarks if there are dozens of images to be inserted. I didn't find any way to either set the cursor or add bookmarks programmatically. Actually, I don't find any usage of the cursor in the built-in RGT functions… I thought it's a basic
  12. Hi again! I'm having a hard time to get the position of a found text in a Word file. I'm able to use the Report Generation toolkit to search+replace text, but I want to highlight the replaced text one way or another. Using the "track changes" option of MS Word would be the best, but changing the font of the replacement and leaving the original text too would also suffice. The reason I'm struggling with it is that there are several text to search for and replace and the texts are sometimes contain other search text (so for example I want to replace X01 with Y but X01.01 with Z). This
  13. Hi again! This time I have the following problem: I want to do simple queries on a small .accdb as a part of a simple tool application. Labview's connectivity toolkit method works fine as far as every user is on the same Office bitness (32 vs 64 bit). But in our case, some machines have 64 bit Office and some 32 bit. This results in driver compatibility issues and our IT policies are so strict that in the near future our local admin rights might vanish too, making driver install requests for a simple tool is too tedious. This 32-64 bit transitional state can last for several months a
  14. Thanks for the replies! As usual, I did things wrong. This time it was with the testing. When I started I tried with the actual property names with the illegal characters. But the tested files (which were chosen randomly) were probably all files that was once re-saved with Diadem. Then I tried with the underscores, this time probably on totally different files which were never re-saved in DiAdem. Funny thing is that I tested multiple times with the underscore, seeminly always on non re-saved files... Anyways, Now I look for both the original property and the fixed property. Thanks An
