I am using this snippet in order to create a mf4 file with a value to text table, found in the examples from asammdf's github.
vals = 5
conversion = {
'val_{}'.format(i): i
for i in range(vals)
}
conversion.update(
{
'text_{}'.format(i): 'key_{}'.format(i).encode('ascii')
for i in range(vals)
}
)
sig = Signal(
np.arange(cycles, dtype=np.uint32) % 30,
t,
name='Channel_value_to_text',
conversion=conversion,
comment='Value to text channel',
)
sigs.append(sig)
mdf.append(sigs, comment='arrays', common_timebase=True)
Is there a way to create a table with ##TX blocks and also ##CC blocks?(in order to simulate a scale conversion)
Thank you!
If anyone needs it, I found the answer and it was simpler than expected.
Create another conversion (i.e conversion2) in the same manner as the first one, then reassign the value of one of the references to it.
conversionBlock = from_dict(conversion)
conversionBlock.referenced_blocks["text_4"] = from_dict(conversion2)
I want to retrieve the current element in LibreOffice Impress to apply changes to it.
For example, I'm trying to retrieve this shape to change the text in it with macros.
I tried to find information with the X-ray tool but without success.
To get the currently selected shape:
oSel = ThisComponent.getCurrentController.getSelection()
oShape = oSel.getByIndex(0)
Print oShape.getString()
To iterate through all shapes in the slide, start with ThisComponent.getDrawPages() and then use XrayTool.
You may also find the following snippet of python code helpful:
def iterate_draw_shapes():
oDrawPage = oDrawPages.getByIndex(1)
for oShape in oDrawPage:
if oShape.supportsService("com.sun.star.drawing.TextShape"):
oTexts = oShape.createEnumeration()
while oTexts.hasMoreElements():
oText = oTexts.nextElement()
oTextPortions = oText.createEnumeration()
while oTextPortions.hasMoreElements():
oTextPortion = oTextPortions.nextElement()
I know there are similar questions out there, but this one is a little different (I think).
I used the MATLAB Compiler to convert a .m to an Excel add-in. When I run the add-in on my machine, it works just fine. When I send it to a colleague, they get the "ActiveX component can't create object" error. They have added the add-in no problem.
Is there something going on here that's easily fixed?
MATLAB code:
function mess = createAndRouteOrderWithStyle()
c = startbbrg();
[num,text] = exportToM();
s = emsx('//blp/emapisvc_beta');
order.EMSX_ORDER_TYPE = text(1);
order.EMSX_SIDE = text(2);
order.EMSX_TICKER = text(3);
order.EMSX_AMOUNT = int32(num(1));
%order.EMSX_LIMIT_PRICE = num(2);
order.EMSX_BROKER = text(4);
order.EMSX_HAND_INSTRUCTION = text(5);
order.EMSX_TIF = text(6);
events = createOrderAndRoute(s,order);
mess = events.ERROR_MESSAGE;
close(s);
end
Excel VBA code:
Sub GO()
Cells(10,10).Formula = "=createAndRouteOrderWithStyle()"
End Sub
I am having a model which takes two input & multiplies them & give the output.
output_1 = input_1 * input_2
I have declared my simulink signals as CustomStorageClass= GetSet
input_1 = Simulink.Signal;
input_1.CoderInfo.StorageClass = 'Custom';
input_1.CoderInfo.CustomStorageClass = 'GetSet';
input_1.CoderInfo.CustomAttributes.GetFunction = 'Get_input_1';
input_1.CoderInfo.CustomAttributes.SetFunction = 'Set_input_1';
input_1.CoderInfo.CustomAttributes.HeaderFile = 'signals.h';
input_2 = Simulink.Signal;
input_2.CoderInfo.StorageClass = 'Custom';
input_2.CoderInfo.CustomStorageClass = 'GetSet';
input_2.CoderInfo.CustomAttributes.GetFunction = 'Get_input_2';
input_2.CoderInfo.CustomAttributes.SetFunction = 'Set_input_2';
input_2.CoderInfo.CustomAttributes.HeaderFile = 'signals.h';
output_1 = Simulink.Signal;
output_1.CoderInfo.StorageClass = 'Custom';
output_1.CoderInfo.CustomStorageClass = 'GetSet';
output_1.CoderInfo.CustomAttributes.GetFunction = 'Get_output_1';
output_1.CoderInfo.CustomAttributes.SetFunction = 'Set_output_1';
output_1.CoderInfo.CustomAttributes.HeaderFile = 'signals.h';
Now I am trying to convert my model to code using simulink coder.
In code generation setting of the model i have selected ert.tlc file in the system target file settings.
But the generated code does not have a Get_input_1() or Get_input_2() call like shown in this link.
http://www.mathworks.com/help/ecoder/ug/getset-custom-storage-classes.html
What i have missed in the setting. Please suggest
I know you probably already solved this issue, but I have also seen this behavior before.
Sometimes MATLAB does not update the header files correctly. If you had set a different configuration for your variable and then made a change involving the header files, I would recommend erasing the *_ert_rtw and slprj folders (they will appear again). It is similar to doing a "Make clean" operation, to ensure that everything is brand new.
I'm trying to make an exercise from Udacity's Full Stack Foundations course. I have the do_POST method inside my subclass from BaseHTTPRequestHandler, basically I want to get a post value named message submitted with a multipart form, this is the code for the method:
def do_POST(self):
try:
if self.path.endswith("/Hello"):
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers
ctype, pdict = cgi.parse_header(self.headers['content-type'])
if ctype == 'multipart/form-data':
fields = cgi.parse_multipart(self.rfile, pdict)
messagecontent = fields.get('message')
output = ""
output += "<html><body>"
output += "<h2>Ok, how about this?</h2>"
output += "<h1>{}</h1>".format(messagecontent)
output += "<form method='POST' enctype='multipart/form-data' action='/Hello'>"
output += "<h2>What would you like to say?</h2>"
output += "<input name='message' type='text'/><br/><input type='submit' value='Submit'/>"
output += "</form></body></html>"
self.wfile.write(output.encode('utf-8'))
print(output)
return
except:
self.send_error(404, "{}".format(sys.exc_info()[0]))
print(sys.exc_info() )
The problem is that the cgi.parse_multipart(self.rfile, pdict) is throwing an exception: TypeError: can't concat bytes to str, the implementation was provided in the videos for the course, but they're using Python 2.7 and I'm using python 3, I've looked for a solution all afternoon but I could not find anything useful, what would be the correct way to read data passed from a multipart form in python 3?
I've came across here to solve the same problem like you have.
I found a silly solution for that.
I just convert 'boundary' item in the dictionary from string to bytes with an encoding option.
ctype, pdict = cgi.parse_header(self.headers['content-type'])
pdict['boundary'] = bytes(pdict['boundary'], "utf-8")
if ctype == 'multipart/form-data':
fields = cgi.parse_multipart(self.rfile, pdict)
In my case, It seems work properly.
To change the tutor's code to work for Python 3 there are three error messages you'll have to combat:
If you get these error messages
c_type, p_dict = cgi.parse_header(self.headers.getheader('Content-Type'))
AttributeError: 'HTTPMessage' object has no attribute 'getheader'
or
boundary = pdict['boundary'].decode('ascii')
AttributeError: 'str' object has no attribute 'decode'
or
headers['Content-Length'] = pdict['CONTENT-LENGTH']
KeyError: 'CONTENT-LENGTH'
when running
c_type, p_dict = cgi.parse_header(self.headers.getheader('Content-Type'))
if c_type == 'multipart/form-data':
fields = cgi.parse_multipart(self.rfile, p_dict)
message_content = fields.get('message')
this applies to you.
Solution
First of all change the first line to accommodate Python 3:
- c_type, p_dict = cgi.parse_header(self.headers.getheader('Content-Type'))
+ c_type, p_dict = cgi.parse_header(self.headers.get('Content-Type'))
Secondly, to fix the error of 'str' object not having any attribute 'decode', it's because of the change of strings being turned into unicode strings as of Python 3, instead of being equivalent to byte strings as in Python 3, so add this line just under the above one:
p_dict['boundary'] = bytes(p_dict['boundary'], "utf-8")
Thirdly, to fix the error of not having 'CONTENT-LENGTH' in pdict just add these lines before the if statement:
content_len = int(self.headers.get('Content-length'))
p_dict['CONTENT-LENGTH'] = content_len

I am doing the same course and was running into the same problem. Instead of getting it to work with cgi I am now using the parse library. This was shown in the same course just a few lessons earlier.
from urllib.parse import parse_qs
length = int(self.headers.get('Content-length', 0))
body = self.rfile.read(length).decode()
params = parse_qs(body)
messagecontent = params["message"][0]
And you have to get rid of the enctype='multipart/form-data' in your form.
In my case I used cgi.FieldStorage to extract file and name instead of cgi.parse_multipart
form = cgi.FieldStorage(
fp=self.rfile,
headers=self.headers,
environ={'REQUEST_METHOD':'POST',
'CONTENT_TYPE':self.headers['Content-Type'],
})
print('File', form['file'].file.read())
print('Name', form['name'].value)
Another hack solution is to edit the source of the cgi module.
At the very beginning of the parse_multipart (around the 226th line):
Change the usage of the boundary to str(boundary)
...
boundary = b""
if 'boundary' in pdict:
boundary = pdict['boundary']
if not valid_boundary(boundary):
raise ValueError('Invalid boundary in multipart form: %r'
% (boundary,))
nextpart = b"--" + str(boundary)
lastpart = b"--" + str(boundary) + b"--"
...
