Hope I did understood what you are trying to ask. First of all you are initializing two variables, in your case i and j that are going to help you iterate through the cells.

i and j will replace in the sum formula the first, second, third and so on row and column. So, instead of =SUM(R" & j & "C:R" & i & "C) you will have =SUM(R1 & "C:R" & 4C).

The difference in between A1 and R1C1 is the way you look at it and reference to it. Using R1C1 notation can help you to iterate easier through the cells. Going to the next cell (to the right) to A1 will be something like: R1C2.

It looks like it used wrong encoding - MacRoman - instead of UTF-8. Probably it is MacOS system.

If I encode it (to bytes) using MacRoman and then decode it back to string using utf-8 then I get correct text

TFS on premise can't restore nuget packages from private feed

Asked 2018-Aug-30 at 15:48

We have TFS Version 16.122.27409.2 and a build server hosted on premise. We are experiencing an issue with our automated build system when the build tries to restore packages from the TFS feed:

Unable to load the service index for source http://ngt-tfs:8080/tfs/NGT-Collection-01/_packaging/ad100c06-9a78-4ff2-b37a-23518a33370b/nuget/v3/index.json.

Response status code does not indicate success: 401 (Unauthorized).

Things I have tried so far:

Turn off automatic proxy detection on build server
Disable anti-virus/firewalls on build server
Add windows account of the build server as the owner on TFS Nuget Feed permissions
Update VS 2017 to the latest version
Try using a nuget.config file in the build definition, instead of picking the feed from the drop-down list

ANSWER

Answered 2018-May-27 at 09:04

How about using a lookahead?

Just to check whether an uppercase character is following it.
But without actually consuming that uppercase character.

And that way the replace string only needs 1 capture group.

deserialize json with children items

Asked 2017-Jan-12 at 16:20

Having to deserialize JSON from an API call. Posting the JSON steam below. Have to get each "area" node. Notice that some have children of children in it (this were I'm having trouble). Didn't even know what JSON was before this time yesterday (said I've been out a while).

What I've figured out: Have Netwonsoft.Json reference added Converted it to XML to see if that helped but thinking staying JSON will have better performance.

vb.net class has the following properties: Area_Name as string ("ID" in JSON) Area_ID as string ("Name" in JSON) Parent_ID as string (Parent "ID" in JSON)

So, need idea where to start to pull all nodes out of the following JSON. -----JSON Stream-----

You need to have one more class "AreaModel" with one property "Areas" in it. So your classes should looks as following.

The index can be placed in shared memory with memory mapped files. Using shared memory can reduce the amount of memory needed when multiple processes are using the same index. In addition, it can not only handle an index with a large number of objects that cannot be loaded into memory, but also reduce time to open it. Since changes become necessary at build time, please add the following parameter when executing "cmake" in order to use shared memory. Note: Since there is no lock function, the index should be used only for reference when multiple processes are using the same index. When you insert more than about 5 million objects, please add the following parameter to improve the search time.
