but how should I continue bidding with this hand? when I bidded 3c , he passed with a hand of 4 clubs and 6 diamonds.

There is no English word "bidded".

The past tense of bid is also bid.

I bid 1♥ today. I bid 1♥ yesterday.

That was really worth the bandwidth?

The "WRIGGLING" convention says it all.With a poor hand with 5+ suit the responder does not wish to play in 1NTx bids xx requesting ,or rather forcing, opener to bid 2C and if that is actually the responders suit he passes or corrects to D/H/S whichever is his suit.Since this is showing a very weak hand opener has to pass compulsorily.With a good hand with which,(when not playing this convention,)normally have redoubled ,or any 4333 hand even if poor ,PASSES.For example,holding 8+ HCP and balanced hand he does not xx but passes.If openers RHO passes the opener if he does not wish to play in 1NTx redoubles asking responder to pass with 8 or more and bid the 4card suit with less HCP. After1NTx with a poor hand and having no long suit but having two four carder suits ,bids the lower ranking suit e.g.with xx,Jxxx,xxx,xxxx he bids 2C.!and opener passes with at least three cards in clubs and else bids 2D without them.In the e.g.hand respnder bids 2H, his other 4 card suit and opener passes since he must possess at least three cards in H as he has only 2 cards in clubs.The general idea of the convention is "To Wriggle" out.There are less chances now that opponents will double a 2 level suit contract (as there can be even a 4-4 fit ).And when the long suit approach has been used there can be even 5-3 or better fit,Anyhow they may find it difficult to x that contract.Somehow,we may escape playing in 1NTx with a poor hand or even penalize opponents (when the 8+ hand passes and opener redoubles).It is advisable that only regular partnerships use this convention.
As regards what to do in the diagrammed example,it is advisable to pass since one knows nothing about partners hand.It may prove costly if any other competitive bid like 3C is thought of.

At least as much as the response it provoked.

You said that you bid 3C which responder passed holding only 4 Cards and he had 6 Diamond cards.I don't blame him as 3C was taken by your partner ,perhaps,as a 5 card suit and a dislike for diamonds.To show support for both minors you should bid ,if at all,2NT a bid which is easy to understand as no one will bid 2Nt when 1NT itself was doubled and more so when partner has shown a poor hand.He would then have easily bid 3 diamonds.You have solid winners and no wasted honors in both majors.Playing Wriggling,I ,in your position ,would certainly have bid 2NT with the given cards.Good Luck with wriggling.
