c# - Loading embedded resource on Windows 7 -

-

I have an app that works fine on my WinXP machine. However, when I try to run it on my Win7 machine, it still fails when it tries to load an embedded resource. Resources are all (I can see them using reflectors).

The rows that have failed are all forms: 

  splash. Image = new bitmap (ContainerForm) .Assembly.GetManifestResourceStream ("SplashTest.Resources.Logo.gif"));

and they all fail with the same exception: 

  exception = 'System.ArgumentException: parameter is not valid. On the system Drawing Bitmap..cracker (stream stream)

I do not understand why it is not working on my Win7 machine but it is on my normal WinXP dev machine.

Any thoughts?

There are not many possible failure modes: Assembly.GetManifestResourceStream () will receive zero if the resource is not found. This will fail with the exception shown by the Betamap constructor. In a bit of a bug, it was supposed to reduce the argument.

Anyhoo, it seems that for some reason the assembly has not been created with bitmap processing on your XP machine. Double-click on Double-Check Manifestation with Ildasm.exe, you will see .source for your name.

Better mouse trap, project + property, to add resources to the resource tab, click the arrow on the Add resource button, add an existing file, and navigate to the file. You can then reference the bitmap directly through the auto-generated property: 

  Splash.Image = Properties.Resources.Logo;

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
